CMX7261, Voice Multi-transcoder

The CMX7261 Multi-transcoder IC is a device supporting multiple speech codecs in a single chip.

When loaded with FI-2.x the CMX7261 is capable of encoding analogue voice into PCM (linear, µ-law or A-law) or G.723.1 data formats at either 5.3kbps or 6.3kbps.

It is capable of decoding PCM or G.723.1 (
