Overview
The Texas Instruments SRC4192IDB is a high-end asynchronous sample-rate converter designed for professional and broadcast audio applications. This device combines a wide input-to-output sampling ratio with outstanding dynamic range and ultra-low distortion. It supports standard audio formats as well as Time Division Multiplexed (TDM) mode, allowing flexible connections to a wide range of audio data converters, digital audio receivers and transmitters, and digital signal processors. The SRC4192 is a standalone, pin-programmed device, operating from a single 3.3-V power supply and available in a 28-pin SSOP package.
