SRC4192 and SRC4193 are asynchronous sample rate converters designed for professional and broadcast audio applications. They 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 SRC4192 and SRC4193 to connect to a wide range of audio data converters, digital audio receivers and transmitters, and digital signal processors. SRC4192 is a standalone pin programmed device, with control pins for mode, data format, mute, bypass, and low group delay functions. SRC4193 is a software-controlled device featuring a serial peripheral interface (SPI) port, which is utilized to program all functions via internal control registers. SRC4192 and SRC4193 may be operated from a single +3.3V power supply. A separate digital I/O supply (VIO) operates over the +1.65V to +3.6V supply range, allowing greater flexibility when interfacing to current and future generation signal processors and logic devices. Both the SRC4192 and SRC4193 are available in a 28-lead SSOP package.
