Product Summary

The AD1890JPZ is a SamplePort Stereo Asynchronous Sample Rate Converter that solves sample rate interfacing and compatibility problems in digital audio equipment.Conceptually, the AD1890JPZ interpolates the input data up to a very high internal sample rate with a time resolution of 300 ps, then decimate down to the desired output sample rate. The AD1890JPZ is intended for 18- and 20-bit professional applications The typical applications of AD1890JPZ include: (1)Digital Mixing Consoles and Digital Audio Workstations; (2)CD-R, DAT, DCC and MD Recorders; (3)Multitrack Digital Audio and Video Tape Recorders; (4)Studio to Transmitter Links; (5)Digital Audio Signal Routers/Switches; (6)Digital Audio Broadcast Equipment; (7)High Quality D/A Converters; (8)Digital Tape Recorder Varispeed Applications; (9)Computer Communication and Multimedia Systems.
