Manufacturer: OKI Electric

Overview: E2U0018-28-81 ¡ Semiconductor MSM7702-01/02/03 ¡ Semiconductor Single Rail CODEC This version: Aug. 1998 MSM7702-01/02/03 Previous version: Nov.

General Description

The MSM7702 is a single-channel CODEC CMOS IC for voice signals ranging from 300 to 3400 Hz with filters for A/D and D/A conversion.

Designed especially for a single-power supply and low-power applications, the device is optimized for telephone terminals in digital wireless systems or ISDN systems.

The MSM7702 utilizes low-voltage operational amplifiers (Op-amps) to provide low-power consumption.

Key Features

  • Single power supply: +2.7 V to +3.8 V.
  • Low power consumption Operating mode: 15 mW Typ. VDD = 3 V Power save mode: 3.6 mW Typ. VDD = 3 V Power down mode: 0.05 mW Typ. VDD = 3 V.
  • ITU-T Companding law MSM7702-01: m/A-law pin selectable MSM7702-02: m-law MSM7702-03: A-law.
  • Built-in PLL eliminates a master clock.
  • Serial data rate: 64/128/256/512/1024/2048 kHz 96/192/384/768/1536/1544/200 kHz.
  • Adjustable transmit gain.
  • Built-in reference.
