CS4955-CQZ

Overview

The CS4955-CQZ is a digital video encoder IC manufactured by Cirrus Logic Inc., designed for NTSC and PAL signal encoding. It features a 48-LQFP (7x7) package with surface-mount installation. The device converts digital video and audio signals into standard analog formats. Operating voltage ranges from 3.14V to 5.25V for both analog and digital supplies. It supports serial data interfaces and operates within a temperature range of -10°C to 70°C. The component is classified as an obsolete product.

Feature Summary

Encodes digital video and audio signals into NTSC or PAL analog formats
Integrates high-performance encoding capabilities in a compact LQFP package
Supports dual power supply requirements for analog and digital sections

Applications

NTSC/PAL digital video encoding systems
Video interface circuits requiring analog output conversion
Embedded video processing applications

Procurement Notes

Verify component obsolescence status prior to procurement planning, as the CS4955-CQZ is officially listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market channels, noting that stock may be limited or restricted. Ensure compatibility with existing design infrastructure before sourcing end-of-life components for production or maintenance purposes.

Selection Notes

Select this component only when NTSC or PAL encoding is required alongside integrated audio handling. Evaluate the 48-LQFP footprint against PCB layout constraints. Consider the operating temperature range and supply voltage specifications for system integration. Assess alternative solutions if current supply chain stability is critical for long-term production needs.

Part Context

This part belongs to Cirrus Logic's video encoder family, specifically targeting standard definition video applications. It serves as an interface solution between digital video sources and analog display or transmission systems. The CS4955 series provides dedicated hardware encoding functions distinct from general-purpose DSPs or codecs.
