The SRC4192 and SRC4193 devices are asynchronous, sample-rate converters designed for professional and broadcast audio applications. The SRC4192 and SRC4193 devices combine a wide input-to-output sampling ratio with outstanding dynamic range and ultra-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 SRC4192 and SRC4193 devices to connect to a wide range of audio data converters, digital audio receivers and transmitters, and digital signal processors.
The SRC4192 device is a standalone, pin-programmed device, with control pins for mode, data format, mute, bypass, and low group-delay functions. The SRC4193 device is a software-controlled device featuring a serial peripheral interface (SPI) port, which is utilized to program all functions through the internal control registers.
The SRC4192 and SRC4193 devices can operate from a single 3.3-V power supply. A separate digital I/O supply (VIO) 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. Both devices are available in a 28-pin SSOP package.
