Datasheet

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).
