PRODUCT OVERVIEW

The AD1896 is a 24-bit, high performance, single-chip, second generation asynchronous sample rate converter. Based on 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 THD + N range of –117 dB to –133 dB depending on the sample rate and input frequency, 142 dB (A-Weighted) dynamic range, 192 kHz sampling frequencies for both input and output sample rates, improved jitter rejection, and 1:8 upsampling and 7.75:1 downsampling ratios. Additional features include more serial formats, a bypass mode, better interfacing to digital signal processors, and a matched-phase mode.
