ML7204-001 - OKI Semiconductor

ML7204-001 VoIP Codec

The ML7204-001 is a speech CODEC for VoIP. As a speech CODEC, this LSI allows selection of G.729.A/G711 and supports the PLC (Packet Loss Concealment) function. With an echo canceler that handles 32 ms-delay and FSK detection/generation, DTMF detection/generation, and tone detection/generation functions, the ML7204-001 is the most suitable LSI for adding the.
