The SRC4184 bines a wide input-to-output sampling ratio with outstanding dynamic range and ultra low distortion. The input and output serial ports support the most mon audio data formats, as well as a time division multiplexed (TDM) format. This allows the SRC4184 to interface to a wide range of audio data converters, digital audio receivers and transmitters, and...
