GSM/GPRS Baseband Processor Data Sheet
Confidential A
MediaTek Confidential Release forMT6252integratesa mixed-signal basebandfront-end
in order to provide a radio interface with flexibility for
efficient customization. It builds in gain /offset
calibration mechanisms and filters with programmable
coefficients for comprehensive compatibility control on
RF modules. MT6252 achieves great MODEM
performance by utilizing a high resolution A/D
converter in the RF downlink path.
MT6252 RF is a low current transceiver to support a
Cenon_WCXtrue quad-band GSM/GPRS cellular system. The
highly integrated RF system implements the high
sensitivity and channel selection receiver, high
using the advanced low leakage CMOS process, in
order to provide an ultra low leakage solution.
Power Management
MT6252 integrates all regulators that a voice-centric
phone needs, including thirteen LDOs optimized for
specific GSM/GPRS baseband sub-systems. In addition
to Li-Ion battery charge function, MT6252 are
equipped with a SIM-level shifter interface, one
open-drain output switch controlling the KPLED and
one LDO specifically driving the vibrator motor.
MT6252’s power management schemes also cover
precision transmission modulator, low phase noise
thermal overload protection, Under-voltage Lock-out
frequency synthesizer, and the digitally controlled
protection (UVLO), over-voltage protection, and the
crystal oscillator. The external components required for
power-on reset/start-up timer, etc.
a GPRS radio design include the Rx SAWs, PA,
switchplexer, X’TAL, and a few passives.
Package
Debug Function
The MT6252 device is offered in an 11.6 mm×12.1 mm,
The JTAG interface enables in-circuit debugging of
305-ball, 0.5 mm staggered pin pitch TFBGA package.
software program with the ARM7EJ-STM core. With
this standardized debugging interface, MT6252
provides developers with a wide set of options in
MediaTek Confidential Release forchoosingARM development kitsfromdifferentthird
party vendors.
Low Power Features
MT6252 offers various low power features to reduce
system power consumption. Features include Pause
Mode of 32 kHz clocking at Standby State, Power
Down Mode for individual peripherals, and Processor
Sleep Mode. In addition, MT6252 is also fabricated
