DPD Demodulator for PA Linearization 1300MHz to 2900MHz IDT Zero-DistortionTM, Glitch-FreeTM DPD Receiver 1 Rev4, January 2014 IDTF1370NBGI Datasheet GENERAL DESCRIPTION This document describes the specification for the IDTF1370 Digital Pre-Distortion Demodulator for PA linearization. This series of devices is offered in 2 variants to cover common UTRA bands. See part number matrix below for additional detail. COMPETITIVE ADVANTAGE In typical basestation transmitters digital pre-distortion is employed to improve the Transmitter performance. The signal coming out of the PA is sampled and the incoming Tx chain I&Q data is pre-distorted to counteract the distortion inherent in the PA. The PA signal is adjusted via a digital step attenuator to a lower level and then sub-sampled at an IF frequency of ~200 MHz which necessitates the need for a highly linear demodulator to downmix to quadrature IF from the Transmit frequency. By sampling IF_I and IF_Q independently and then digitally combining these signals, an effective doubling of the sample rate can be achieved. Any distortion in this path will degrade the performance of the DPD algorithm. By utilizing an ultra-linear demodulator w/integrated DSA such as the IDTF1370, the ACLR and/or power consumption of the full Tx system can be improved significantly.

If the F1370 is programmed after applying DC power, the following power-on sequence is not needed. Note: To use power on sequence, SW_LATCH cannot be grounded permanently. The power-on sequence should be: 1. CSb & SW_LATCH must be set low at power-on 2. Once powered on, first set SW_LATCH high, then set CSb high 3. Proceed with normal programming. The default state after using power-on sequence: Maximum attenuation RF_INX selected Normal operation (not Standby Mode) SERIAL PROGRAMMING The device is programmed via the serial port by asserting Chip Select (CSb).

DPD Demodulator for PA Linearization 1300MHz to 2900MHz IDT Zero-DistortionTM, Glitch-FreeTM DPD Receiver 7 Rev4, January 2014 PRELIMINARY DATASHEET IDTF1370NBGI Datasheet TO PROGRAM THE SERIAL INTERFACE: If CSb is de-asserted (set to high), the serial interface will ignore the CLK line. Once CSb is asserted (set to low), the serial interface will recognize the CLK and any data present on DATA will be clocked into the registers with each rising CLK edge. After the 16th CLK cycle, and before the 17th CLK cycle, CSb must be de-asserted to successfully program the part with the desired bytes. If CSb is de-asserted before the 16th CLK cycle, or after the 17th CLK cycle, there is no guarantee that the correct bytes will be programmed and the user will have to re-program the interface in accordance with the aforementioned procedure. SW_LATCH PROGRAMMING SEQUENCE When SW_LATCH is pinned high during the programming sequence, “RFSW” and “ENb” registers cannot be programmed and therefore will not toggle. If SW_LATCH is pinned low during the programming sequence, the “RFSW” and “ENb” register will toggle. This can be prevented with the “Programming Sequence” below. SEQUENCE FOR PROGRAMMING REGISTERS A<2>:A<0> 1) SW_Latch = 1; CSb = 0 2) CLK in 8- or 16-bit word, do not de-assert (pull high) CSb 3) Set SW_LATCH = 0 while CSb = 0 remains) 4) With SW_Latch = 0, set CSb = 1 5) Set SW_Latch = 1 6) Program complete SPECIAL NOTE REGARDING PHASE OF I & Q: When LO is high-side injected, IF_I leads IF_Q by 90 degrees When LO is low-side injected, IF_Q leads IF_I by 90 degrees SDATA 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 SCLK 0 0 0 0 0 1 0 1 RFSW ENb CSb (solid) SW_LATCH (dashed) RFSW

The device provides an added attenuation range from 0 dB to 25.5 dB in 0.5 dB steps. A “high” or “1” bit corresponds to attenuation stepped IN, while a “low” or “0” bit corresponds to attenuation stepped OUT. Because the first and last bits of the Data Word are not presently used by the F1370, two additional hex character pairs exists for each of those in this table. For example, data words of either H00, H80, or H01 (binary “00000000,” “10000000,” or 00000001) will place the F1370 in its minimum attenuation state. Likewise, data words of either H66, HE6, or H67 (binary “01100110” or “11100110” or “01100111”) will place the F1370 in its maximum attenuation state of 25.5 added attenuation.

1 SW_LATCH
Stand-by latch. Pull Low or Ground for Normal Operation. If left floating, this input will be internally pulled high, disabling SPI writes to ENb (Standby) and RF SW bits (A0, A2). 2, 4, 5, 6, 8, 11,15, 21, 22, 30, 31, 32, 33, 34, 36 GND Ground these Pins. 3 RF_INY Alternate RF Input. Separated from RF_INX by internal SP2T. AC couple to this pin. Internally matched to 50 ohms 9, 16, 25 VCC Power Supply. Bypass to GND with capacitors shown in the Typical Application Circuit as close as possible to pin.
10 LO_ADJ Connect the specified resistor from this pin to ground to set the
LO path ICC. This IS a current setting resistor 12 LO_IN LO Input. AC couple to this pin. Internally matched to 50 ohms Recommended Connection is Ground 14 STBY STBY Mode. Pull this pin high for Standby mode (30mA). Pull low or Ground for normal Operation 17, 18 IF_BIAS_I IF_BIAS_Q Connect the specified resistor from this pin to ground to set the IF amplifier bias reference. This is NOT a current setting resistor 19, 20 IF_I+, IF_I- In-Phase Mixer Differential IF Output. Connect pullup inductors from each of these pins to VCC (see the Typical Application Circuit). 23, 24 IF_Q-, IF_Q+ Quadrature Mixer Differential IF Output. Connect pullup inductors from each of these pins to VCC (see the Typical Application Circuit).
26 CSb
Chip Select Bar. The falling edge initiates a programming cycle and the rising edge latches the programmed shift register data into the active register.
27 DATA Serial Data Input
28 CLK Serial Clock Input
35 RF_INX Main RF Input. Separated from RF_INY by internal SP2T. AC couple to this pin. Internally matched to 50 ohms — EP Exposed Pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses multiple ground vias to provide heat transfer out of the device into the PCB ground planes. These multiple via grounds are also required to achieve the noted RF performance.

26 CSb 1.75 1.6M 27 DATA 1.75 1.6M 28 CLK 1.75 1.6M POWER SUPPLIES All supply pins should be bypassed with external capacitors to minimize noise and fast transients. Supply noise can degrade noise figure and fast transients can trigger ESD clamps and cause them to fail. Supply voltage change or transients should have a slew rate smaller than 1V/20uS. In addition, all control pins should remain at 0V (+/-0.3V) while the supply voltage ramps or while it returns to zero.
