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)
