CML Microcircuits CMX7261 multi-transcoder IC
CML Microcircuits has launched the single chip G.711/G.729A/CVSD (speech compression) full duplex multi-transcoder device, the CMX7261.
Suitable for software-defined radio, voice-over IP applications, wireless private branch exchange and privacy-type digital voice communications, it has built-in G.711, G.729A and CVSD algorithms and is a flexible IC that creates toll quality speech for many applications without sacrificing performance.
Providing analog to digital and digital to analog conversion and with no additional DSP or programming, the device is built on CML’s FirmASIC technology.
The function of speech compression is to produce a compact representation of speech sounds that when reconstructed sound as close to the original as possible.
Other key features include voice activity detection, C-Bus host serial control/data interface, multiple choice of input and output sources, streaming transfers, four GPIO and encoder/decoder test mode support which allows verification of bit exactness and high audio quality for various supported codecs.
It operates from a 3.3 V supply and includes selectable power saving modes.
