The WM8804 is a high performance consumer mode S/PDIF transceiver with support for 1 received channel and 1 transmitted channel.

The device is supplied in a 20-lead Pb-free SSOP package.

The WM8804 is an IEC-60958 compatible S/PDIF transceiver with support for one received S/PDIF data stream and one transmitted S/PDIF data stream.

The receiver performs data and clock recovery, and transmits recovered data from the chip either through the digital audio interface or, alternatively, the device can loop the received S/PDIF data back out through the S/PDIF transmitter producing a de-jittered S/PDIF transmit data stream. The recovered clock may be routed to a high drive output pin for external use. If there is no S/PDIF input data stream the PLL can be configured to output all standard MCLK frequencies or it can be configured to maintain the frequency of the last received S/PDIF data stream.
