ML7202-001

ML7202-001 2-Channel Echo Canceler with Multifunction ADPCM Transcoder FEDL7202-001-01 Issue Date: Sep. 08, 2004 GENERAL DESCRIPTION The ML7202-001 is an LSI supporting 2-channel transmit/receive. Each channel of transmit/receive has a built-in line echo canceler and full-duplex ADPCM transcoder. The ML7202-001, which performs functions such as the DTMF tone and single tone generation, and tone detection, transmit/receive data mute, gain control, and VOX, is ideally suited to applications such as basestations of ADPCM-based cordless telephone systems like Asian-prevailing PHS (Personal Handyphone System). FEATURES  Single 3.3 V power supply (DVDD1, 2, AVDD: 3.0 to 3.6 V)  ADPCM: ITU-T Recommendation G.726 (32 kbps)  PCM interface code format: ITU-T Recommendation G.711 (64 kbps), -law or A-law selectable  Built-in echo canceler Echo attenuation: 30 dB （typ.） white noise Cancelable echo delay time: 64ms （max）  Serial ADPCM and PCM transmission rate: 64 to 204...
