Multifunction ADPCM CODEC
FEDL7029-03
Issue Date: Feb. 18, 2004
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)
