Part Number: MT6625L, MT6625LN
Function : 4-in-1 Connectivity RF Chip
Package: 40-pin QFN Type
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 lowspeed 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.
1. MT6625L is a 4-in-1 connectivity RF chip which contains front-ends of a 2.4GHz Wi-Fi and Bluetooth transceiver, a 5GHz Wi-Fi transceiver, a GPS receiver and an FM receiver.
2. MT6625L supports integrated passive device to save footprint on PCB and cost due to Wi-
Fi/Bluetooth/GPS external BoM (bill of materials) in a 40-pin QFN package.
3. Supports GPS external LNA.
4. Option of IPD: MT6625L offers front-end components flexibility for various filtering / rejection requirements, multiple antenna configurations (e.g., 2-antenna and 3-antenna). Its sister product MT6625 offers higher integration level by integrating a 2.4G/5G diplexer.
