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.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 transfer
Allows selection of Frame/DMA (slave) interface
• Echo canceler for handling 32 ms delay
• DTMF detection
• DTMF generation (the tone generation function enables generation of DTMF
signals)

ports)
• General-purpose I/O ports
64-pin package: Equipped with 7 ports (with some of them having secondary
function allocation)
100-pin package: Equipped with 21 ports (with some of them having secondary
function allocation)
• Two types of built-in linear PCM CODEC (CODEC_A and CODEC_B)
