For use in DSP-, FPGA-, and MCU-based systems, the CMX7861 analog front end combines codec, embedded signal processing, and auxiliary system support for interfacing between analog and digital systems. Features include programmable digital filters, a four-channel SAR ADC, four DACs, GPIO sub-systems, two synthesized clock generators, and a C-BUS/SPI master interface. The device supports two general operating modes: codec and modem. Codec mode is for applications requiring a general-purpose codec and modem mode suits scenarios where the CMX7861 transmits and receives modulated data. CML MICROCIRCUITS INC., Winston-Salem, NC.
