DESCRIPTION

The WM8805 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.

FEATURES

• S/PDIF (IEC60958-3) compliant.

• Advanced jitter attenuating PLL with low intrinsic period jitter of 50 ps RMS.

• S/PDIF recovered clock using PLL, or stand alone crystal derived clock generation.

• Supports 10 – 27MHz crystal clock frequencies.

• 2-wire / 3-Wire serial or hardware control interface.

• Programmable Audio data interface modes:

  - I2S, Left, Right Justified or DSP

  -  16/20/24 bit word lengths

• 8 channel receiver input and 1 channel transmit output.

• Auto frequency detection / synchronisation.

• Selectable output status data bits.

• Up to 8 configurable GPO pins.

• De-emphasis flag output.

• Non-audio detection including DOLBY™ and DTS™.

• Channel status changed flag.

• Configurable clock distribution with selectable output MCLK rate of 512fs, 256fs, 128fs and 64fs.

• 2.7 to 3.6V digital and PLL supply voltages.

•28-lead SSOP package.
