Product Summary

The WM8805GEDS is a high performance consumer mode S/PDIF transceiver with support for 8 received Channels 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. The WM8805GEDS may be used under software control or stand alone hardware control modes. In software control mode, both 2-wire with read back and 3-wire interface modes are supported. The applications of the WM8805GEDS include: Surround Sound AV processors and Hi-Fi systems, Music industry applications, DVD-P/DVD-RW, Digital TV.
