SRC4190IDBR 3 Description

The SRC4190 device is an asynchronous sampleandratebroadcastSRC4190applications.combines a wide input-to-output sampling ratio withoutstanding dynamic range and low distortion. Inputand output serial ports support standard audioformats, as well as a Time Division Multiplexed(TDM) mode. Flexible audio interfaces allow theSRC4190 to connect to a wide range of audio dataconverters, digital audio receivers and transmitters,and digital signal processors.TheThe SRC4190 is a standalone pin-programmeddevice, with control pins for mode, data format, mute,bypass, and low group delay functions.The SRC4190 may be operated from a single 3.3-Vpower supply. A separate digitalI/O supply (VIO)operates with a 1.65-V to 3.6-V supply, allowingflexibility when interfacing to current andgreaterfuture generation signal processors and logic devices.The SRC4190 is available in a 28-pin SSOPpackage.Device Information(1)Simplified Application Diagram
