应用功能： SamplePort Stereo Asynchronous Sample Rate Converters The AD1890 and AD1891 SamplePorts™ are fully digital, stereoAsynchronous Sample Rate Converters (ASRCs) that solve samplerate interfacing and compatibility problems in digital audio equipment. Conceptually, these converters interpolate the input data upto a very high internal sample rate with a time resolution of 300 ps,then decimate down to the desired output sample rate.
