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.
