Analog Devices AN-291 Application Note Asynchronous Clock Interfacing with the AD7878
The document discusses timing constraints for the AD7878, a 12-bit A/D converter with a FIFO memory. It explains that while synchronous clock interfacing is recommended in the data sheet, it is not suitable for every microprocessor and may reduce throughput. An alternative asynchronous method is presented that allows operation at any sampling frequency up to 100 kHz.
