ML7029中文资料冲电线数据手册PDF规格书

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)
