Overview

The WM8804GEDS/V is a high performance consumer mode S/PDIF transceiver with support for 1 received channel and 1 transmitted channel. A crystal derived, or externally provided high quality master clock is used to allow low jitter recovery of S/PDIF supplied master clocks. Generation of all typically used audio clocks is possible using the high performance internal PLL. A dedicated CLKOUT pin provides a high drive clock output. A pass through option is provided which allows the device simply to be used to clean up (de-jitter) the received digital audio signals. The device may be used under software control or stand alone hardware control modes. In software control mode, both two-wire with read back and three-wire interface modes are supported. Status and error monitoring is built-in and results can be read back over the control interface, on the GPO pins or streamed over the audio data interface in ‘With Flags’ mode (audio data with status flags appended). The audio data interface supports I²S, left justified, right justified and DSP audio formats of 16-24 bit word length, with sample rates from 32 to 192ks/s. The device is supplied in a 20-lead Pb-free SSOP package.
