描述 Description

GENERAL DESCRIPTION
The ML7029 is a single channel ADPCM CODEC IC which performs mutual transcoding between the analog voice band signal and 32 kbps ADPCM serial data.FEATURES
• Single 3 V Power Supply Operation       (VDD: 2.7 to 3.6 V)
• ADPCM Algorithm: ITU-T G.726      (32 kbps, 24 kbps, 16 kbps)
• Full-Duplex Transmit/Receive Operation
• Transmit/Receive Synchronous Mode Only
• PCM Data Format: µ-law
• Serial PCM/ADPCM Transmission Data Rate: 64 kbps to 2048 kbps (when SYNC = 8 kHz)
• Low Power Consumption
   Operating Mode: 18 mW Typ. (VDD = 3.0 V, SYNC = 8 kHz)
   Power-Down Mode: 0.03 mW Typ. (VDD = 3.0 V, SYNC = 8 kHz)
• Sampling Frequency: 6 kHz to 21 kHz selectable (However, there are limitations to 16 kHz or higher frequencies)
• Master Clock Frequency: Sampling frequency × 1296
                                     When SYNC = 8 kHz: 10.368 MHz
• Transmit/Receive Mute, Transmit/Receive Programmable Gain Control
• Side Tone Path with Programmable Attenuation (8-Step Level Adjustment)
• Serial MCU Interface Control
• Package:
   30-pin plastic SSOP (SSOP30-P-56-0.65-K) (ML7029)
