ML7204-001 - VoIP Codec

General Description

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.

Key Features

  • Power supply voltage Digital power supply voltage (DVDD0, 1, 2): 3.0 to 3.6 V Analog power supply voltage (AVDD): 3.0 to 3.6 V.
  • Speech CODEC: G.729.A (8 kbps)/G.711 (64 kbps) µ-law and A-law (supports individual setting for transmission and reception) Supports ITU-T G.711 Appendix 1 compliant PLC (Packet Loss Concealment) function Supports the 2-channel processing function (for 3-way communication).
  • Built-in FIFO buffer (640 bytes) for transmission/reception data tran.

OKI Semiconductor ML7204-001 VoIP CODEC FEDL7204-001DIGEST-01 Issue Date: Aug. 12, 2004 GENERAL DESCRIPTION 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 VoIP function to TAs and routers. FEATURES • Power supply voltage Digital power supply voltage (DVDD0, 1, 2): 3.0 to 3.6 V Analog power supply voltage (AVDD): 3.0 to 3.6 V • Speech CODEC: G.729.A (8 kbps)/G.711 (64 kbps) µ-law and A-law (supports individual setting for transmission and reception) Supports ITU-T G.
