Description
The combination of the CS5381 Analog-to-Digital Converter and CS8421 Asynchronous Sample Rate Converter creates an analog-to-digital conversion system with an asynchronous digital decimation filter that is virtually immune to interface or network jitter. In addition, the CS8421 adds a multi-channel Time Division Multiplexed (TDM) output format option....
