WM8804GEDS/RV

Overview

The WM8804GEDS/RV is a high-performance consumer mode S/PDIF transceiver supporting one received channel and one transmitted channel. It operates within a digital supply voltage range of 2.7V to 3.6V and an operating temperature range of -40°C to +85°C. The device features an advanced jitter-attenuating PLL with low intrinsic period jitter of 50 ps RMS, enabling low-jitter recovery of S/PDIF master clocks or standalone crystal-derived clock generation. It supports sample rates from 32kHz to 192kHz and accommodates I2S, left justified, right justified, and DSP audio formats with 16/20/24-bit word lengths. Supplied in a 20-lead SSOP package.

Feature Summary

• IEC-60958-3 compliant S/PDIF transceiver with 1-channel receiver and 1-channel transmitter.
• Advanced jitter attenuating PLL with 50 ps RMS intrinsic period jitter.
• Supports programmable audio data interfaces: I2S, Left/Right Justified, DSP (16-24 bit, 32-192 kHz).
• Configurable via 2-wire or 3-wire serial interface, or hardware control mode.

Applications

• AV processors and Hi-Fi systems
• Music industry applications
• DVD-P/DVD-RW drives
• Digital TV

Procurement Notes

Verify the 'RV' suffix indicates tape and reel packaging with a reel quantity of 2,000 units. Confirm the component is Pb-free and meets MSL3 moisture sensitivity standards. Ensure the ordering part number matches the specific temperature range (-40 to +85 °C) required for the application.

Selection Notes

Select this component for designs requiring S/PDIF data recovery and transmission with low jitter performance. Ensure the system provides a master clock between 10 MHz and 27 MHz for the internal PLL. Verify that the available control interface (I2C/SPI compatible 2-wire or 3-wire) aligns with the host controller capabilities.

Part Context

The WM8804GEDS/RV is the tape and reel variant of the WM8804GEDS/V. Both share identical electrical specifications and functionality. The primary distinction lies in the shipping packaging format, with the RV suffix denoting the reel configuration suitable for automated surface mount assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and register maps if considering alternative S/PDIF transceivers from other manufacturers.

FAQ

What is the intrinsic period jitter specification of the WM8804?

The WM8804 features an advanced jitter attenuating PLL with a low intrinsic period jitter of 50 ps RMS.

How is the control mode determined for the WM8804?

The control mode is determined by the state of the SDIN/HWMODE pin during power up or hardware reset. A low state configures hardware control mode, while a high state configures software control mode.

What audio data formats does the WM8804 support?

The device supports I2S, left justified, right justified, and DSP audio formats with word lengths of 16, 20, or 24 bits.
