SRC4190IDB

Product Summary

The SRC4190IDB is a 192kHz Stereo Asynchronous Sample Rate Converter. It is designed for professional and broadcast audio applications. The SRC4190IDB combines a wide input-to-output sampling ratio with outstanding dynamic range and low distortion. Input and output serial ports support standard audio formats, as well as a Time Division Multiplexed (TDM) mode. Flexible audio interfaces allow the SRC4190 to connect to a wide range of audio data converters, digital audio receivers and transmitters, and digital signal processors. The applications of the SRC4190IDB include digital mixing consoles, digital audio workstations, audio distribution systems, broadcast studio equipment, high-end a/v receivers, general digital audio processing.
