AD1895

192 kHz立体声异步采样速率转换器 192 kHz Stereo Asynchronous Sample Rate Converter

Product Details

The is a 24-bit, high-performance, single-chip, second-generation asynchronous sample rate converter. Based upon Analog Devices experience with its first family of asynchronous sample rate converters the AD1890 to AD1893, the AD1895 offers improved performance and additional features.

This improved performance includes a minimum THD+N of -115 dB for all input frequencies and sample rates, 128 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 a TDM mode to cascade multiple AD1895, more serial formats for better interfacing to digital signal processors and a bypass mode.
