WM8804GEDS/V

Overview

The WM8804GEDS/V is a high-performance consumer mode S/PDIF transceiver manufactured by Cirrus Logic (formerly Wolfson Microelectronics). It supports one received channel and one transmitted channel, utilizing an advanced jitter-attenuating PLL with low intrinsic period jitter of 50 ps RMS. The device operates on a 2.7V to 3.6V supply voltage and functions within a temperature range of -40°C to +85°C. It accepts sample rates from 32kHz to 192kHz and interfaces via I2S, Left Justified, Right Justified, or DSP formats. Packaged in a 20-lead SSOP, it provides de-jittered digital audio signal processing for professional audio applications.

Feature Summary

• IEC-60958-3 compliant S/PDIF transceiver with 1 Rx and 1 Tx channel
• Advanced PLL with 50 ps RMS intrinsic period jitter
• Supports I2S, Left/Right Justified, and DSP audio data formats
• Configurable 2-wire or 3-wire serial control interface

Applications

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

Procurement Notes

Verify the ordering suffix 'GEDS/V' corresponds to the 20-lead SSOP package with a -40 to +85°C temperature range and Pb-free construction. Confirm Moisture Sensitivity Level (MSL) 3 requirements for storage conditions prior to assembly. Ensure the specific revision matches the design documentation, as register maps may vary between hardware revisions.

Selection Notes

Select this component when a dedicated S/PDIF transceiver with low-jitter clock recovery is required. The internal PLL allows for clean clock generation from crystal inputs or recovered S/PDIF clocks. Ensure the system supports the 2.7V–3.6V supply range and that the 20-SSOP package fits the PCB layout constraints. Verify compatibility with the desired control interface (2-wire vs. 3-wire) based on host controller capabilities.

Part Context

This part is produced by Cirrus Logic Inc., having originated from Wolfson Microelectronics plc. The datasheet indicates production data status as of March 2009, Revision 4.5. The 'WM8804' designation identifies the core functional block, while 'GEDS/V' specifies the commercial grade, SSOP package, and lead-free finish.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult manufacturer obsolescence notices or contact the supplier directly for current alternative recommendations if end-of-life status applies.
