AD1890 Datasheet (Analog Devices) - SamplePort Stereo Asynchronous Sample Rate Converters

AD1890, SamplePort Stereo Asynchronous Sample Rate Converters

The lowpass filter has been designed so that full 20 kHz bandwidth is maintained when the input and output sample clock frequencies are as low as 44.1 kHz.

If the output sample rate drops below the input sample rate, the bandwidth of the input signal is (continued on Page 4) The AD1890 and AD1891

AD1890 Features

* Automatically Sense Sample Frequencies

* No Programming Required Tolerant of Sample Clock Jitter Smooth Transition When Sample Clock Frequencies Cross Accommodate Dynamically Changing Asynchronous Sample Clocks 8 kHz to 56 kHz Sample Clock Frequency Range 1:2 to 2:1 Ratio Between Sample Clocks
