3 Description

The SRC4190 device is an asynchronous sample

rate converter designed for professional and

broadcast audio applications. The SRC4190

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 SRC4190 is a standalone pin-programmed

device, with control pins for mode, data format, mute,

bypass, and low group delay functions.

The SRC4190 may be operated from a single 3.3-V

power supply. A separate digital I/O supply (VIO)

operates with a 1.65-V to 3.6-V supply, allowing

greater flexibility when interfacing to current and

future generation signal processors and logic devices.

The SRC4190 is available in a 28-pin SSOP

package.
