WM8805GEDS/V

Overview

The WM8805GEDS/V is a high-performance consumer mode 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 operates on a 2.7V to 3.6V supply within a -40°C to +85°C temperature range. It supports sample rates from 32kHz to 192kHz and offers programmable audio data interfaces including I2S, Left Justified, Right Justified, and DSP formats with 16/20/24 bit word lengths. The component is housed in a 28-lead SSOP package.

Feature Summary

• Advanced jitter attenuating PLL with low intrinsic period jitter of 50 ps RMS
• Supports 8 channel receiver inputs and 1 channel transmit output
• Programmable audio data interface modes: I2S, Left, Right Justified, or DSP
• Compatible with 2-wire or 3-wire serial control interfaces

Applications

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

Procurement Notes

Verify the specific ordering suffix for packaging requirements. The /V suffix indicates tube packaging, while /RV denotes tape and reel quantities of 2,000 units. Confirm moisture sensitivity level MSL3 compliance and peak soldering temperature limits of 260°C during assembly planning.

Selection Notes

Select this component when designing systems requiring multi-channel S/PDIF reception with clock recovery capabilities. Ensure the design accommodates separate digital (DVDD) and PLL (PVDD) supplies maintained within 0.3V of each other. Verify that the host controller supports either 2-wire or 3-wire serial protocols for configuration.

Part Context

Manufactured by Cirrus Logic Inc., this device belongs to the Wolfson Microelectronics legacy product line. It serves as a digital interface solution for converting between S/PDIF streams and standard digital audio interfaces like I2S. The part is designed for high-fidelity audio processing where low jitter performance is critical.

Replacement Considerations

The WM8804GEDS/V is a compatible alternative offering similar functionality but with only one receiver input channel instead of eight. Both parts share identical pinouts, electrical characteristics, and package types, facilitating direct substitution in single-channel designs.
