Introduction
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. It can also transcode data between PCM formats and G.723.1. Input and output signals may be passed through the C-BUS interface, the PCM port or the on-chip converters (ADC/DAC). The device utilises CML’s proprietary FirmASIC component technology. On-chip sub-systems are configured by a Function Image data file that is uploaded during device initialisation and defines the device's function and feature set. The Function Image can be loaded automatically from a host μc over the C-BUS serial interface or from an external memory device. The device's functions and features can be enhanced by subsequent Function Image releases, facilitating in-the-field upgrades. The CMX7261 operates from a 3.3V supply and includes selectable powersaving modes. It is available in a 64-VQFN (Q1) or a 64-LQFP (L9) package.
Features
- Half-duplex operation
- Full-duplex operation
- Codec support:
