  • Page 20: System Overview

    3.1.1 System Overview MT6223D is an entry level chipset solution with class 12 GPRS/GSM modem. It integrates not only analog baseband but also power management blocks into one chip and can greatly reduce the component count and make smaller PCB size. Besides, MT6223D is capable of SAIC (Single Antenna Interference Cancellation) and AMR speech.
  • Page 21 Radio MT6223D integrates a mixed-signal Baseband front-end in order to provide a well-organized radio interface with flexibility for efficient customization. It contains gain and offset calibration mechanisms, and filters with programmable coefficients for comprehensive compatibility control on RF modules. This approach also allows the usage of a high resolution D/A Converter for controlling VCXO or crystal, thus reducing the need for expensive TCVCXO.
