DESCRIPTION
The SRC4190 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 (V_IO) operates
over the 1.65-V to 3.6-V supply range, allowing greater flexibility when interfacing to current and future
generation signal processors and logic devices. The SRC4190 is available in an SSOP-28 package.
