1 System Overview
1.1 Functional Block Diagram
MT6625L is a 4-in-1 connectivity chip which contains a 2.4GHz Wi-Fi/Bluetooth transceiver front-end, a 5GHz Wi-Fi transceiver front-end, a GPS receiver front-end and a complete FM receiver, along with Integrated Passive Device (IPD) in a QFN40 pacakge. Simplified block diagram and how MT6625L is used are shown in Error! Reference source not found.. An always-on low-dropout regulator (ALDO) provides supply voltage to top control logics in MT6625L. The top control logics controls each subsystem independently. Each subsystem also has dedicated LDOs. A thermal sensor and a low - speed ADC (Analog-to-Digital Converter) is provided to monitor MT6625L’s temperature variation. MT6625L does not have its dedicated crystal oscillator. It uses either an external (maybe temperature compensated) oscillator or clock source from companion chips in the platform such as MT6166. For Wi-Fi and Bluetooth, MT6625L provides an advanced switching mechanism which allows fast switching between Wi-Fi and BT modes. Hardware sharing and reuse is maximized. The transceiver front-ends are on MT6625L while the ADC/DAC (Analog-to-Digital Converter/Digital-to-Analog Converter) are in the companion modem chip. The interface driver/receiver buffer is designed to drive PCB trace loading. The GPS IP in MT6625L is similar to Wi-Fi/Bluetooth such that the ADC/DAC is in the companion modem chip. In contrast, the FM system integrates the modem and ADC in MT6625L, and no interface drivers/buffers are required. The IPD of MT6625L integrates 2.4G WiFi/BT balun and its matching network; and a GPS matching network (Figure 1-1). MEDIATEK CONFIDENTIAL FOR rong.xiang@ hymost.com USE ONLY

3.4 Power-on/off Sequence
MT6625L uses three supply voltages, 1.8V, 2.8V and 3.3V. Specific power-on/off sequence must be followed as described below. 1.8V IO and internal control logic use 1.8V, and this supply voltage needs to be powered on prior to 2.8V and 3.3V for functioning properly. The functionality of MT6625L will not be guaranteed if 2.8V or 3.3V power is supplied prior to this 1.8V supply. 2.8V and 3.3V MEDIATEK CONFIDENTIAL FOR rong.xiang@ hymost.com USE ONLY

3.5.3 Protocals
There are 3 main interfaces for MT6625L. 3-wire SPI: Generally used for all systems (BT/Wi-Fi/FM/GPS) 6-wire bus: High-speed interface, especially for BT and Wi-Fi FM 2-wire: Utilized as a simplified interface modified from I2S. This interface also defines MT6625L strap-pin modes. Do not add pull-up/pull-down to this interface. Failing to follow this recommendation will lead to unexpected MT6625L operation. 3.5.3.1 3-Wire The 3-wire SPI protocol of MT6625L is the main interface to access Wi-Fi/BT/FM/GPS/efuse command registers. The bit number of SDATA depends on different operating conditions , as shown in Figure 3-3. SEN SCLK SDATA 25/33/49-bit data Figure 3-3. 3-wire SPI timing diagram 3.5.3.2 6-bit Bus MT6625L has a dedicated 6-bit bus to control Wi-Fi and BT radios. The related control definitions depend on operating modes and conditions. One example BT operation scenario is shown in Figure 3-4. MEDIATEK CONFIDENTIAL FOR rong.xiang@ hymost.com USE ONLY

3.5.3.3 FM 2-wire Bus
A modified 2-wire interface instead of standard I2S protocol for FM audio data stream is used in MT6625L, as shown in Figure 3-5. F2W_CLK F2W_DATA 64-bit data Figure 3-5. FM 2-wire interface
3.6 MT6625L TOP Building Blocks
3.6.1 Reference Clock
The reference clock source needs to satisify 0.8 Vpp with rising/falling time of 5 nsec and phase noise of －149 dBc/Hz at 100-kHz offset frequency. The clock buffers draw 90 μA. The first stage buffer employs ac-coupled architecture to ensure proper amplification even with weak input clock whose swing is less than thresh voltage of transistors. There is a tie-low switch in the buffer to each block (i.e. WBT, GPS, FM, THADC and DIG) to guarantee well-defined voltage for input ports of blocks mentioned above.
3.6.2 Thermal ADC
A low-speed ADC converts the output of thermal sensor to 8-cycle-average or 16-cycle-average ADC code which represents the current chip temperature near the THADC. The temperature coverage range is between -40 and 120 degree Celsius. The chip top control may do corresponding adjustment (such as PA/TX gain switching) based on such temperature information.

3.6.3 Always-on LDO
A low-power bandgap reference provides biasing currents for internal LDO as well as reference voltages for THADC’s temperature sensing. An always-on LDO provides an internal 1.2V voltage to digital circuits from an external supply of 1.8V. In normal operation, the BG circuit generates the reference voltage for the LDO. In sleep mode, the BG+LDO consumes a small quiescent current of ~25uA. The LDO output voltage and driving capability are programmable.
3.7 Wi-Fi/BT
MT6625L Wi-Fi/BT is a high performance and highly-integrated dual-band RF transceiver fully front-end topology is implemented to achieve maximum hardware sharing between 2.4GHz/5GHz Wi- Fi and Bluetooth with integrated TR-switches. MT6625L also features a self calibration scheme to compensate the process and temperature variation to maintain high performance. The calibration is performed automatically right after the system boot-up.
3.7.1 Wi-Fi/BT Specifications
The WLAN/BT radio characteristics are described in this section. Unless otherwise specified, all specifications are measured at the RF port which is depicted in the following figure. Unlike most devices available today which requires matching network or filters between antenna port and RF ports (defined in Figure 3-), due to the integration of integrated passive device (IPD), the RF port and antenna port of MT6625L can be directly connected by a 50Ohm trace.

The power amplifier is capable of transmitting 20dBm CCK power and 8dBm BDR power for Bluetooth class 1 operation. 3.7.3 2.4GHz Wi-Fi/BT Rx For Bluetooth, MT6625L uses a low IF receiver architecture. An image-rejecting mixer down-converts the RF signal to the IF with the LO from the synthesizer, which supports different clock frequencies. The mixer output is then converted to digital signal, down-converted to baseband for demodulation. A fast AGC enables the effective discovery of device within the dynamic range of the receiver. For Wi-Fi, a direct down-conversion receiver architecture is used, which includes a high linearity and low noise figure LNA, and a quadrature passive mixer and a bandwidth-programmable low-pass filter with DC offset cancellation embedded. 3.7.4 2.4GHz Wi-Fi/BT Sx A fractional-N frequency synthesizer is implemented to support both Wi-Fi and Bluetooth LO signal. The frequency synthesizer is capable of supporting various crystal clock frequencies. VCO operates at 2.5 times of RF frequency to avoid any coupling with RF front-end circuitry. An LO generation is employed to divide the VCO signal by 2.5 and generate I/Q quadrature signals. 3.7.5 5GHz WiFi Tx The 5G transmitter utilizes the most cost efficient direct up architecture and integrates a high performance PA with on-chip balun. The data are digitally modulated in the baseband processor from the companion baseband chip, then up-converted to 5GHz RF channels through the DA converter, low-pass filter, IQ up-converter and power amplifier. The power amplifier is capable of transmitting 17dBm OFDM power. 3.7.6 5GHz WiFi Rx A direct down-conversion receiver architecture is also used in 5G WiFi Rx, which consists of a high linearity, low noise figure single-ended LNA with on-chip integrated T/R switch, a quadrature passive mixer and a bandwidth-programmable low-pass filter with DC offset cancellation embedded. 3.7.7 5GHz WiFi Sx A-band Sx is an independent RF-PLL for a-band Wi-Fi RF use. It adopts 8/5xLO architecture while VCO frequency is RF frequency x 8/5 to avoid xX pulling. Thus, it is composed of PLL, offset LO mixer and a repeater. Its integrated PN from 100kHz to 10MHz is less than 0.45 degree to ensure good Tx low-power EVM. It supports multi-frequency XTAL frequency from 19.2MHz to 52MHz. Typical application is 26MHz reference clock input. In MT6625L application, typical Sx supply voltage MEDIATEK CONFIDENTIAL FOR rong.xiang@ hymost.com USE ONLY

Sx output frequency is 2xLO frequency (~11GHz), and after IQ DIV2 of Tx and RX, it generates I/Q quadrature phase to TRX mixer. 3.8 FM
3.8.1 FM Radio Descriptions
FM radio subsystem integrates complete receiver supporting 65-108 MHz bands with 50kHz tuning step. MT6625L performs fast channel seek/scan algorithm to validate 206 carrier frequencies (87.5 ~ 108MHz) in 6 seconds. In addition to receiving FM audio broadcasting, the digital RDS/RBDS data system is supported as well. The integrated FM receiver utilizes state-of-the-art digital demodulation/modulation technique to achieve excellent performance. In order to achieve high SINAD, good sensitivity and excellent noise suppression, the FM receiver adopts adaptive demodulation scheme to optimize the Rx system performance in all ranges of signal quality by referring to the Channel Quality Index (CQI). When receiving poor signals, MT6625L not only enhances the ACI rejection capability but also soft-mutes annoying noise to provide good perception quality. The FM radio subsystem supports long antenna, which is usually in the earphone on the mobile device and short antenna, which is usually a FPC short antenna or shared antenna with GSM. Figure 3-6.

3.9 GPS
3.9.1 GPS Radio Descriptions
The GPS RF consists of a low-IF receiver and a fractional-N frequency synthesizer. GPS LO is set to 1571.42MHz resulting in an IF frequency of 4.0MHz, with the baseband filter configured as complex BPF. All RF/analog blocks operate under a 1.3V supply voltage. The radio architecture allows for configurations of GPS/Galileo-only, GPS/Galileo-Glonass or GPS/Galileo-Beidou modes, which are set by LO and baseband filter configurations. In the case of GPS/Galileo-only reception, LO (fLO_GPS) is set to 1571.328MHz resulting in an IF frequency of 4.092MHz, with the baseband filter configured as complex BPF. On the other hand, for simultaneous GPS/Galileo and Glonass dual reception, LO (fLO_GG) is set to 1588.608MHz. As a result, the GPS/Galileo signal becomes the image of the Glonass satellite signal with an IF frequency of 13.1MHz, and the baseband filter in this case is configured as real LPF. The Glonass signal is separated from the GPS/Galileo image signal in digital baseband. Similarly, with LO (fLO_GB) set to 1568.256MHz, the resulting IF frequency is about 7.1MHz for GPS/Galileo and Beidou dual reception. Only one synthesizer is needed to support this architecture. All RF/analog blocks operate under a 1.3V supply voltage.
3.9.1.1 GPS Mode Definition
The receiver sets LO to 1571.42MHz and IF filter to complex BPF with center frequency of 4MHz and bandwidth of 2MHz. GPS/GALILEO mode The receiver sets LO to 1571.42MHz and IF filter to complex BPF with center frequency of 4MHz and bandwidth of 4MHz. GPS/GLONASS mode The receiver sets LO to 1588.608MHz and IF filter to LPF with bandwidth of 15MHz. GPS/BEIDOU mode The receiver sets LO to 1568.256MHz and IF filter to LPF with bandwidth of 9MHz.
