The CMX7261 is capable of encoding analogue voice into PCM (linear, -law or A-law), CVSD or G.729A data formats. It is capable of decoding PCM, CVSD and G.729A back to analogue voice. It can also transcode data between PCM, CVSD and G.729A. Input and output signals may be passed through the C-BUS interface, the PCM port or the on-chip convertors (ADC/DAC). The device utilises CMLs 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 C 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. Note that text shown in pale grey indicates features that will be supported in future versions of the device.
