3.6 Digital Baseband(MSM8255)
3.6.1 General Description
A. Features (MSM8255)
-Higher integration to reduce PCB surface area, power consumption, time-to-market, and BOM osts while adding
capabilities and processing power.
ଝ
Baseband functions, including multiple hardware cores.
ଝ
radioOne® RF transceiver functions (Rx and Tx, both eliminating their intermediate requency [IF] components).
ଝ
Wireless connectivity and analog functions – Bluetooth®, FM radio, audio codec, and ouchscreen ADC support.
ଝ
Rx inter-stage SAW filters are not required.
-Integrated hardware cores eliminate multimedia coprocessors, providing superior image quality and resolution
for mobile devices while extending application times.
