AD1895AYRSZ Datasheet PDF - ADI

The AD1895AYRSZ is a 24-bit high performance single-chip second generation asynchronous Sample Rate Converter offers improved performance and additional features. This improved performance includes a THD + N range of -115 to -122dB depending on sample rate and input frequency, 128dB (A-Weighted) dynamic range, 192kHz sampling frequencies for both input and output sample rates, improved jitter rejection and 1:8 up-sampling and 7.75:1 down sampling ratios. Additional features include more serial formats, a bypass mode and better interfacing to digital signal processors. It has a 3-wire interface for the serial input and output ports that supports left-justified and I²S interface. Additionally, the serial output port supports TDM Mode for daisy-chaining multiple AD1895s to a digital signal processor. The AD1895 sample rate converts the data from the serial input port to the sample rate of the serial output port.
