662M-03LFT

Overview

The Renesas ICS662M-03LFT is a video clock generator designed for high-definition television (HDTV) audio and video applications. It generates synchronous clocks derived from HDTV streams, specifically supporting audio sampling rates of 256x and 384x. The device provides a 27 MHz output clock for video MPEG applications. It utilizes phase-locked loop (PLL) technology to achieve low phase noise and precise multiplication ratios with zero ppm error. The component operates on a single 3.3V power supply and is housed in an 8-pin SOIC package.

Feature Summary

• Generates synchronous clocks from HDTV reference inputs for audio and video synchronization
• Provides dedicated 27 MHz output clock for video MPEG processing applications
• Supports multiple audio sampling rate multipliers including 256x and 384x configurations
• Delivers low phase noise and long-term jitter performance via PLL technology

Applications

• High-definition television (HDTV) audio systems
• Video MPEG application clocking
• Consumer video equipment timing generation

Procurement Notes

Verify the specific suffix LFT indicates lead-free RoHS compliance compared to non-LFT variants. Confirm current availability status as the base model has been marked obsolete in some distributor records. Ensure the 8-SOIC package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing HDTV systems requiring precise derivation of audio sampling clocks from video reference signals. It is suitable for applications needing stable 27 MHz outputs for MPEG video processing. Consider the 8-SOIC package constraints and 3.3V operating voltage during board layout and power supply design phases.

Part Context

This part belongs to the ICS662 series of video clock generators manufactured by Renesas Electronics. The series focuses on providing synchronized timing solutions for consumer video electronics. The 662M variant specifically addresses the needs of HDTV signal processing chains where accurate frequency multiplication from standard video references is required.

Replacement Considerations

Renesas recommends the 5P35021B-000NDGI as a manufacturer-recommended alternative. Verify functional compatibility and pinout alignment before substitution.
