Hot-selling and scarce AD1896AYRSZ 192 kHz Stereo Asynchronous Sample Rate Converter SSOP28 spot stock

Product Descriptions

The AD1896 is a 24-bit, high performance, single-chip, secondgeneration 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 aTHD + 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.

The AD1896 has a 3-wire interface for the serial input and output ports that supports left-justified, I²S, and right-justified(16 -, 18-, 20-, 24-bit) modes. Additionally, the serial output​ port supports TDM mode for daisy-chaining multiple AD1896s to a digital signal processor.The serial output data is dithered down to 20, 18, or 16 bits when 20-, 18-, or 16-bit output data is selected. The AD 1896 sample rate converts the data from the serial input port to the sample rate of the serial output port. The sample rate at the serial input port can be asynchronous with respect to the output sample rate of the output serial port. The master clock to the AD1896, MCLK, can be asynchronous to both the serial input and output ports.
