MSM7731-02GA Product Details

GENERAL DESCRIPTION
The MSM7731 is an IC device developed for portable, handsfree communication with built-in line echo canceler, acoustic echo canceler, and transmission signal noise canceler. Built-in to the voice signal interface is a linear CODEC for the analog interface on the acoustic-side, and a linear CODEC for the analog interface on the line side. On the line-side, in addition to the analog interface, there is also a µ law PCM/16-bit linear digital interface. 
Equipped with gain and mute controls for data transmission and reception, a µ-law PCM/16-bit linear digital interface for memo recording and message output, and transfer clock and sync clock generators for digital communication, this device is ideally suited for a handsfree system.
FEATURES
• Single 3 V Power Supply Operation (2.7 to 3.6 V)
• Built-in 2-channel (line and acoustic) echo canceler
- Echo attenuation : 35 dB (typ.) for white noise
- Cancelable echo delay time :
  Line echo canceler + acoustic echo canceler : Tlined = 27 ms (max.), Tacoud = 59 ms – Tlined (max.)
  Acoustic echo canceler only : Tacoud = 59 ms (max.)
• Built-in transmission signal noise canceler
- Noise attenuation : 17 dB (typ.) for white noise 40 dB (typ.) for single tone
• Built-in 2-channel CODEC
- Synchronous transmission and reception enables full duplex operation
• Built-in analog input gain amp stage (max. gain = 30 dB)
• Analog output configuration : Push-pull drive (can drive a 1.2 kΩ load)
• Built-in transmit slope filter
• Digital interface coding formats : µ-law PCM, 16-bit linear (2's complement)
• Digital interface sync formats : Normal-sync, short-frame-sync
• Built-in digital transmission clock generators
- Sync clock (SYNC) : 8 kHz output
- Transmission clock (BCLK) : 64 kHz output (µ-law PCM)/128 kHz output (16-bit linear)
• Digital transmission rate
- External input : 64 to 2048 kbps
- Internal generation : 64 kbps (µ-law PCM)/128 kbps (16-bit linear)
• Fixed digital interface sync clock (SYNC) enables automatic power-down
• Master clock frequency : 19.2 MHz
- Compatible with crystal oscillator and crystal
• Low power consumption
- Operating mode : typ. 35 mA (when VDD = 3.0 V in a silent mode)
- Power down operation : typ. 0.02 mA (when VDD = 3.0 V in a silent mode)
• Control by both the serial microcomputer interface and parallel port is possible
• Transmit/receive mute function, transmit/receive programmable gain setting
• Package : 64-pin plastic QFP (QFP64-P-1414-0.80-BK)(Product name: MSM7731-02GA)
