The SRC4392IPFB is a 2-channel high-performance asynchronous Sample Rate Converter with a digital audio interface receiver (DIR) and transmitter (DIT), two audio serial ports and flexible distribution logic for interconnection of the function block data and clocks. The DIR and DIT are compatible with the AES3, S/PDIF, IEC 60958 and EIAJ CP-1201 interface standards. The audio serial ports, DIT and SRC may be operated at sampling rates up to 216kHz. The DIR lock range includes sampling rates from 20 to 216kHz. The SRC4392 is configured using on-chip control registers and data buffers, which are accessed through either a 4-wire serial peripheral interface (SPI) port, or a 2-wire Philips I²C bus interface. Status registers provide access to a variety of flag and error bits, which are derived from the various function blocks. An open drain interrupt output pin is provided and is supported by flexible interrupt reporting and mask options via control register settings.
