Introduction
Phone description
RAP3Gv4 is the main digital baseband ASIC in the device. It contains functionality for both WCDMA and GSM
EDGE. The cellular baseband is constructed around Radio Application Processor (RAP3GS2v4) and mixed signal
ASIC PEARL_J. RAP3GS2v4 is used as a single chip solution, which means that all UI components are connected
to RAP3GS2v4.
N2200 is the main audio and energy management controller for the phone. The mixed-signal functionality
is in one mixed-signal ASIC. N2200 includes blocks for charger control, SMPS power supplies for VCORE, VIO
and LEDs, linear regulators for RF and BB supplies, level shifter functions, A/D converters, audio and RTC.
Bluetooth and FM radio are physically integrated in one single ASIC.
