CEP2224 Overview

CEP2224 thumbnail
  • SUMMARY - The CEP2224 is the lowest cost 24-bit, 48kHz option for implementing CobraNet connectivity. The module provides 2 digital audio inputs and 2 digital audio outputs, fully bi-directional. In addition, the CEP2224 supplies high quality stereo differential analog outputs.
  • uC HOST OPTIONS - The CEP2224 has an asynchronous serial host interface, so it may be easily controlled by any host uC with a UART.
  • DAC - The CEP2224 includes a high quality differential outout DAC for direct interface to products which have analog inputs. The DAC is 24 bits, 48kHz sampling rate, and achieves a 105dB S/N ratio.
