The AD1896 is a sample rate converter; it is second generation and 24-bit, high-performance, single-chip, and asynchronous. Based upon Analog Devices experience with its first asynchronous sample rate converter, the AD1890, the AD1896 offers improved performance and additional features.
This improved performance includes a minimum THD+N of 117dB for all input frequencies and sample rates, 142 dB dynamic range, 192 kHz 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 TDM mode to cascade multiple AD1896, a bypass mode, better interfacing to digital signal processors and a matched phase mode.
