WM8805GEDS/R Datasheet PDF - Wolfson Microelectronics

●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.

●APPLICATIONS
