3.7 Analog Main Processor

A. Baseband Transmit section

This section generates in-phase and quadrature BB modulated GMSK signals (BT = 0.3) in
accordance with GSM 05.05 Phase 2 specifications.
The transmit channel consists of a digital GMSK modulator, a matched pair of 10-bit DACs and a
matched pair of reconstruction filter.

B. Baseband Receive section

This section consists of two identical ADC channels that process baseband in-phase(I) and
quadrature(Q) input signals.
Each channel consists of a coarse switched capacitor input filter, followed by a high-order sigma-
delta modulator and a lowpass digital filter.

C. Auxiliary section

This section contains two auxiliary DACs(AFC DAC, IDAC) for system control.
This section also contains AUX ADC and Voltage Reference.

AUX ADC: 6 channel 10 bits

AFC DAC: 13 bits

IDAC: 10 bits

D. Voiceband section

Receive audio signal from MIC. LG-510W use differential configuration.
Send audio signal to Speaker. LG-510W use differential configuration.
It interconnect with external device like main microphone, main speaker, ear-phone and Hands free
kit through the VINNORP, VINNORN, VOUTNORP, VOUTNORN, VINAUXP, VINAUXN,
VOUTAUXP, VOUTAUXN and BUZZER port.

VINNORP, VINNORN: Main MIC positive/negative terminal

VOUTNORP, VOUTNORN: Main Speaker positive/negative terminal

VINAUXP, VINAUXN: Hands free kit mike positive/negative terminal

VOUTAUXP, VOUTAUXON: Hands free kit speaker positive/negative terminal

BUZZER: Buzzer Output terminal
