WM8805GEDS/RV

Overview

The WM8805GEDS/RV is a high-performance S/PDIF transceiver supporting eight received channels and one transmitted channel. It complies with IEC60958-3 standards and features an advanced jitter-attenuating PLL with 50 ps RMS intrinsic period jitter. The device accepts digital audio interfaces in I2S, Left Justified, Right Justified, or DSP formats with 16/20/24-bit word lengths at sample rates from 32kHz to 192kHz. Operating on a 2.7V to 3.6V supply within a -40°C to +85°C range, it utilizes a 28-lead SSOP package.

Feature Summary

• Supports 8-channel S/PDIF reception and 1-channel transmission
• Advanced PLL with 50 ps RMS intrinsic period jitter
• Programmable audio interface modes: I2S, Left/Right Justified, DSP (16-24 bit)
• Configurable clock distribution with MCLK outputs of 64fs, 128fs, 256fs, and 512fs

Applications

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

Procurement Notes

Verify the 'RV' suffix indicates Tape & Reel packaging with a reel quantity of 2,000 units. Confirm Moisture Sensitivity Level (MSL) 3 compliance for storage conditions prior to assembly. Ensure the component matches the Pb-free specification and 28-lead SSOP physical dimensions.

Selection Notes

Select this model when eight independent S/PDIF inputs are required alongside a single output. The internal PLL allows for low-jitter clock recovery from S/PDIF streams or standalone crystal generation between 10MHz and 27MHz. Verify compatibility with 2-wire or 3-wire serial control interfaces based on system design constraints.

Part Context

This component belongs to the WM8805 series of digital interface transceivers manufactured by Cirrus Logic (formerly Wolfson Microelectronics). The GEDS designation identifies the 28-lead SSOP package variant, while RV specifies the tape and reel delivery format. It serves as a bridge between consumer S/PDIF sources and digital audio processing cores.

Replacement Considerations

The WM8804GEDS/V is a compatible alternative offering identical electrical characteristics but limited to one receiver channel and one transmitter channel. Both devices share the same package type and control interface protocols.
