Consumer Microcircuits Limited CMX7261
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 (both rates) back to analogue voice.| Part No. | CMX7261 |
