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).
