Theory of Operation The RFFC5071A and RFFC5072A are wideband RF frequency converter chips which include a fractional-N synthesizer and a low noise VCO core. The RFFC5071A has an LO signal multiplexer, two LO buffer circuits, and two RF mixers. The RFFC5072A has a single LO buffer circuit and one RF mixer. Both devices have an integrated voltage reference and low drop out regulators supplying critical circuit blocks such as the VCOs and synthesi zer. Synthesizer programming, device configuration and control are achieved through a mixture of hardware and software cont rols. All on-chip registers are programmed through a simple 3- wire serial interface. VCO The VCO core in the RFFC5071A and RFFC5072A consists of three VCOs which, in conjunction with the integrated LO dividers of /2 to /32, cover the LO range of 85MHz to 4200MHz. Each VCO has 128 overlapping bands which are used to achieve low VCO gain and optimal phase noise performance across the whole tuning range. The chip automatically selects the correct VCO (VCO auto-select) and VCO band (VCO coarse tuning) to generate the desired LO frequency based on the values programmed into the PLL1 and PLL2 registers banks. The VCO auto-select and VCO coarse tuning are triggered every time ENBL is taken high, or if the PLL re-lock self clearing bit is programmed high. Once the correct VCO and band have been selected the PLL will lock onto the correct frequency. During the band selection process, fixed capacitance elements are progressively connected to the VCO resonant circuit until the VCO is oscillating approximately at the correct frequency. The output of this band selection, CT_CAL, is made available in the read- back register. A value of 127 or 0 in this register indicates th at the coarse tuning was unsucce ssful, and this will also be in di- cated by the CT_FAILED flag also available in the read-back register. A CT_CAL value between 1 and 126 indicates a success- ful calibration, the actual value being dependent on the desired frequency as well as process variation for a particular device. The band select process will center the VCO tuning voltage at about 0.8V, compensating for manufacturing tolerances and pro- cess variation as well as environmental fa ctors including temperature. The VCOs have temperature compensation circuits so the PLL will hold lock over the entire operating temperature range of -40°C to +85°C. This is true regardless of the tempera- ture at which the VCO band selection is performed. The VCO gain is also held stable across te mperature, maintaining consis- tent loop bandwidth and synthesizer phase noise. The RFFC5071A and RFFC5072A feature a differential LO input to allow the mixer to be driven from an external LO source. The fractional-N PLL can be used wi th an external VCO driven into this LO input, which may be useful to reduce phase noise in some applications. This may also require an external op-amp, dependant on the tuning voltage required by the external VCO. In the RFFC5071A the LO signal is routed to mixer 1, mixer 2, or both mixers depending on the state of the MODE pin (or MODE bit if under software control) and the value of the FULLD bit. Setting FULLD high puts the device into Full Duplex mode and both mixers are enabled. Fractional-N PLL The RFFC5071A and RFFC5072A contain a charge pump-based frac tional-N phase locked loop (PLL) for controlling the three VCOs. The PLL includes automati c calibration systems to counteract the effe cts of process and envi ronmental variations, ensuring repeatable loop response and phase noise performance. As well as the VCO auto-select and coarse tuning, there is a loop filter calibration mechanism which can be enabled if required. This operates by adjusting the charge pump current to maintain loop bandwidth. This can be useful for applications where the LO is tuned over a wide frequency range. The PLL has been designed to use a reference frequency of between 10MHz and 104MHz from an external source, which is typically a temperature controlled crystal oscillator (TCXO). A re ference divider (divide by 1 to divide by 7) is supplied and should be programmed to limit the frequency at the phase detector to a maximum of 52MHz. Two PLL programming banks are provided, the first bank is preceded by the label PLL1 and the second bank is preceded by the label PLL2. For the RFFC5071A these banks are used to program mixer 1 and mixer 2 respectively, and are selected automati- cally as the mixer is selected using MODE. For the RFFC5072A mixer 2 and register bank PLL2 are normally used.

The output of this high frequency prescalar then enters the N divider, which is a fractional divider containing a dual-modulus prescaler and a digitally spur-compensated fractional sequence generator. This allows very fine frequency steps and minimizes fractional spurs. The fractional energy is randomized and appears as fractional noise at frequency offsets above 100kHz which will be attenuated by the loop filter. An external loop filter is used, giving flexibility in setting loop bandwidth for optimizing phase noise and lock time, for example. The synthesizer step size is typically 1.5Hz when using a 26MHz reference frequency. The exact step size for any reference and LO frequency can be calculated using the following formula: (FREF * P) / (R * 224 * LO_DIV) Where FREF is the reference frequency, R is the reference division rati o, P is the prescalar division ratio, and LO_DIV is the LO divider value. Pin 26 (GPO4) can be configured as a lock detect pin. The lock status is also available in the read-back register. The lock detect function is a window detector on the VCO tuning voltage. The lock flag will be high to show PLL lock which corresponds to the VCO tuning voltage being within the specified range, typically 0.30V to 1.25V. The lock time of the PLL will depend on a number of factors; including the loop bandwidth and the reference frequency at the phase detector. This clock frequency determines the speed at which the state machine and internal calibrations run. A 52MHz phase detector frequency will give fastest lock times, of typically <50secs when using the PLL re-lock bit. Phase Detector and Charge Pump The phase detector provides a current output to drive an active loop filter. The charge pump output current is set by the value contained in the P1_CP_DEF and P2_CP_DEF fields in the loop filter configuration register. The charge pump current is given by approximately 3 A/bit, and the fields are 6 bits long . This gives default value (31) of 93 A and maximum value (63) of 189A. If the automatic loop bandwidth calibration is enabled the charge pump current is set by the calibration algorithm based upon the VCO gain. The phase detector will operate with a maximum input frequency of 52MHz. Loop Filter The active loop filter is implemented using the on-chip low no ise op-amp with external resistors and capacitors. The internal configuration of the chip is shown below with the recommended active loop filter. The op-amp gives a tuning voltage range of typically +0.1V to +2.4V. The recommended loop filter shown is designed to give the lowest integrated phase noise for refer- ence frequencies of between 26MHz and 52MHz. The external loop fi lter gives the flexibility to optimize the loop response for any particular application and combination of reference and VCO frequencies.

The typical input will be a 0.8Vp-p clipped sine wave, which should be AC-coupled into the reference input. When the PLL is not in use, it may be desir- able to turn off the internal reference circuits, by setting the REFSTBY bit low, to minimize current draw while in standby mode. On cold start, or if REFSTBY is programmed low, the reference circuits will need a warm-up period. This is set by the SU_WAIT bits. This will allow the clock to be stable and immediately avai lable when the ENBL bit is asserted high, allowing the PLL to assume normal operation. If the current consumption of the reference circuits in standby mode, typically 2mA, is not critical, then the REFSTBY bit can be set high. This allows the fastest startup and lock time after ENBL is taken high. Wideband Mixer The mixers are wideband, double-balanced Gilbert cells. They support RF/IF frequencies from 30MHz up to 6000MHz. Each mixer has an input port and an output port that can be used for either IF or RF (in other words, for up- or down-conversion). The mixer current can be programmed to between about 15mA and 45mA depending on linearity requirements. The majority of the mixer current is sourced through the output pins via either a ce nter-tapped balun or an RF choke in the external matching cir- cuitry to the supply. The RF mixer input and output ports are differential and require baluns and simple matching circuits optimized to the specific application frequencies. A conversion gain of approximatel y -2dB (not including balun losses) is achieved with 100 differen- tial input impedance, and the outputs driving 200 differential load impedance. Increasing the mixer output load increases the conversion gain. The mixer has a broadband common gate input. The input impe dance is dominated by the resistance set by the mixer 1/gm term, which is inversely proportional to the mixer current setting. The resistance will be approximately 85 at the default mixer current setting (100). There is also some shunt capacitance at the mixer input, and the inductance of the bond wires (about 0.5nH on each pin) to consider at higher frequencies. The following diagram is a simple model of the mixer input impedance: The mixer output is high impedance, consisting of approximately 2k resistance in parallel with some capacitance, approxi- mately 1pF dependent on PCB layout. The mixer output does not require a conjugate matching network. It is a constant current output which will drive a real differential load of between 50Ω and 500Ω, typically 200Ω. Since the mixer output is a constant current source, a higher resistance load will give higher output voltage and gain. A shunt inductor can be used to resonate with the mixer output capacitance at the frequency of interest. This inductor may not be required at lower frequencies where the impedance of the output capacitance is less significant. At hi gher output frequencies the inductance of the bond wires (about 0.5nH on each pin) becomes more significant. Above about 4500MHz, it is beneficial to lower the output load to 50 to mini- mize the effect of the ouput capacitance. The following diagram is a simple model of the mixer output: RFFC507xA Mixer Input 0.5nH 0.5nH Rin Typ 850.5pF RFFC507xA Mixer Output 0.5nH 0.5nH 1K 1pF 1K

The mixers can be set up to operate in half duplex mode (1 mixer active) or full duplex mode (both mixers active). This selection i s done via control of MODE and by setting the FULLD bit. When in full duplex mode, either PLL register bank can be used, the LO signal is routed to both mixers. Serial Interface All on-chip registers in the RFFC5071A and RFFC5072A are programmed using a proprietary 3-wire serial bus which supports both write and read operations. Synthesizer programming, device configuration, and control are achieved through a mixture of hardware and software controls. Certain functions and operations require the use of hardware controls via the ENBL, MODE, and RESETB pins in addition to programming via the serial bus. Alternatively there is the option to control the chip completely via the serial bus. The serial data interface can be configured for 4-wire operation by setting the 4WIR E bit in the SDI_CTRL register high. Then pin 26 is used as the data out pin, and pin 32 is the serial data in pin. Hardware Control Three hardware control pins are provided: ENBL, MODE, and RESETB. The ENBL pin has two functions: to enable the analog circuits in the chip and to trigger the VCO auto-selection and coarse tun- ing mechanisms. The VCO auto-selection and coarse tuning is in itiated when the ENBL pin is taken high. Every time the fre- quency of the synthesizer is reprogrammed, ENBL has to be asserted high to initiate these mechanisms and then to initiate the PLL locking. Alternatively following the programming of a new frequency the PLL re-lock self clearing bit could be used. The RESETB pin is a hardware reset control that will reset all digital circuits to their startup state when asserted low. The device includes a power-on-reset function, so this pin should not normal ly be required, in which case it should be connected to the positive supply. The MODE pin controls which mixer(s) and PLL programming register bank is active. Serial Data Interface Control The normal mode of operation uses the 3-wire serial data inte rface to program the device registers, and three extra hardware control lines: MODE, ENBL and RESETB. When the device is under software control, achieved by setting the SIPIN bit in the SDI_CTRL register high, then the hardware can be controlled via the SDI_CTRL register . When this is the case, the three hardware control lines are not required. If the device is under software control, pins 1 and 9 can be configured as general purpose outputs (GPO).

The device address pins (15 and 16) ADD1 and ADD2 are used to set the address of each part. On power up, and after a reset, the devices ignore the address pins ADD1 and ADD2 and any data presented to the serial bus will be programmed into all the devices. However, once the ADDR bit in the SDI_CTRL register is set, each device then adopts an address according to the state of the address pins on the device. General Purpose Outputs The general purpose outputs (GPOs) can be controlled via the GPO register and will depend on the state of MODE since they can be set in different states corresponding to either mixer path 1 or 2. For example, the GPOs can be used to drive LEDs or to control external circuitry such as switches or low power LNAs. Each GPO pin can supply approximately 20mA load current. The output voltage of the GPO high state will drop with increased current drive by approximately 25mV/mA. Similarly the output voltage of the GPO low state will rise with increased current, again by approximately 25mV/mA. External Modulation The RFFC5071A and RFFC5072A fractional-N synthesizer can be used to modulate the frequency of the VCO. There are two dedicated registers, EXT_MOD and FMOD, which can be used to configure the device as a modulator. It is possible to modulate the VCO in two ways: 1.Binary FSK The MODSETUP bits in the EXT_MOD register are set to 11. GPO3 is then configured as an input and used to control the signal frequency. The frequency deviation is set by the MODSTEP and MODULATION bits in the EXT_MOD and FMOD registers respec- tively. The modulation frequency is calculated according to the following formula: Where MODULATION is a 2's complement number and FPD is the phase detector frequency. 2.Continuous Modulation The MODSETUP bits in the EXT_MOD register are set to 01. The frequency deviation is set by the MODSTEP and MODULATION bits in the EXT_MOD and FMOD registers respectively. The VCO frequency is then changed by writing a new value into the MOD- ULATION bits, the VCO frequency is instantly updated. An arbi trary frequency modulation can then be performed dependant only on the rate at which values are written into the FMOD register.
