CS493105-CLZ

Overview

The CS493105-CLZ is a member of the Cirrus Logic CS493XX family, specifically designed for broadcast audio applications. It functions as a multi-standard audio decoder DSP capable of processing compressed digital audio formats including Dolby Digital (AC-3), MPEG-2 AAC, and MPEG-1 stereo. The device supports PES layer decoding for A/V synchronization and features an 8-channel output architecture with dual-zone capability. It accommodates sample rates up to 192 kHz at 24-bit resolution and includes dynamic channel remapping. The component utilizes a CMOS process and is housed in a lead-free plastic LCC-44 package.

Feature Summary

• Supports Dolby Digital, MPEG-2 AAC, and MPEG-1 stereo decoding standards
• Provides 8-channel output with dual-zone functionality
• Enables dynamic channel remapping for flexible speaker configurations
• Includes PES layer decode for precise audio/video synchronization

Applications

• Broadcast receivers and transmitters
• Digital television sets
• Satellite and cable set-top boxes
• Audio processing modules for media players

Procurement Notes

Verify the specific suffix CLZ indicates lead-free compliance and plastic packaging. Confirm the exact functional subset against the CS4931X broadcast sub-family documentation. Ensure firmware licensing requirements are met for the targeted decoder algorithms before procurement.

Selection Notes

Select this part when broadcast-specific decoding such as MPEG-1/2 and AC-3 is required without DVD Audio MLP support. Compare against the CS4930X series if lossless audio decoding is needed. Evaluate memory interface requirements for external RAM expansion if larger buffer delays are necessary for the application.

Part Context

This component belongs to the CS493XX Multi-Standard Audio Decoder Family, which superseded the earlier CS4923 through CS4929 series. The family is segmented into distinct market-oriented parts, with the CS4931X line dedicated to broadcast applications requiring robust handling of standard compressed audio streams.

Replacement Considerations

Direct replacements within the same family include CS493112-CL or CS493115-CL. Verify pin compatibility and firmware configuration files, as different suffixes may imply variations in boot modes or package types.
