Highly integrated single chip solution
o Voice processor with Hardware Accelerator
o 3 ADC (Analog to Digital Converter)
o 2 DAC (Digital to Analog Converter)
o RAM, ROM
o On-chip microphone amplifier
o SHI, UART interface to external controller
Low power consumption (typically 30mW with all signal processing features on)
High performance
o Powerful AEC (acoustic echo cancellation) (65dB)
o Superior full-duplex
o Supports 1 & 2 microphone modes
o Differential I/O to reduce RF interference and increase noise immunity
o Dynamic range control (DRC) to increase voice intelligibility
o Side tone cancellation of 25 to 35dB
o Acoustic echo tail length coverage: 64 to 100ms
o Mic_in & Line_in PGA (programmable gain amplification) range from
-2dB to +26dB
o Line_out & Spk_out PGA range from -29dB to +2dB
o On the fly switching between various bypass mode to voice processing mode
Extended bypass modes support, configurable main and reference microphone (MIC0 or MIC1)
Main mic to LINE_OUT, LINE_IN to SPK_OUT, no gain or configurable gain
Reference mic to LINE_OUT, LINE_IN to SPK_OUT, no gain or configurable gain
Main mic to SPK_OUT, LINE_IN to LINE_OUT, no gain (Self-loop back)

o Mic_in and Line-in AGC
o Speaker equalization and volume enhancement in noisy environment
Supports 2 types of clock inputs: 4.096MHz or 13MHz
