9173B-01CS08LFT

Application Specific Clock/Timing Overview

The Renesas ICS9173B-01CS08LFT is a video genlock PLL and frequency multiplier IC housed in an 8-SOIC package. It operates on a single 5V supply (4.75V to 5.25V) and supports output frequencies ranging from 1.25 MHz to 75 MHz. The device features one LVCMOS output and accepts reference clock inputs between 12 kHz and 1 MHz. Designed for phase-detector and VCO circuit implementation, it enables precise frequency multiplication for synchronization applications.

Application Specific Clock/Timing Feature Summary

• Integrates phase-detector and VCO circuit blocks for analog PLL frequency multiplication
• Optimized for genlock system synchronization requirements
• Supports wide reference clock input range for flexible full output clock coverage

Application Specific Clock/Timing Applications

• Video genlock systems requiring precise clock synchronization
• Frequency multiplier circuits for video signal processing
• Reference clock distribution in professional video equipment

Application Specific Clock/Timing Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verify availability through authorized distributors or secondary markets. Confirm lot dates and storage conditions carefully due to end-of-life status. Ensure compatibility with existing design specifications before procurement. No new production units are expected.

Application Specific Clock/Timing Selection Notes

Select this part when a dedicated video genlock PLL with integrated VCO is required. It suits designs needing 5V operation and LVCMOS outputs up to 75 MHz. Consider pinout compatibility and thermal performance within the SOIC package. Evaluate alternative active parts if long-term supply stability is critical for the product lifecycle.

Application Specific Clock/Timing Part Context

The ICS9173B series belongs to Renesas' video timing and synchronization family. It provides analog PLL functionality for generating stable clocks from lower-frequency references. The device simplifies board design by integrating essential PLL components into a compact surface-mount package suitable for consumer and professional video electronics.

Application Specific Clock/Timing Replacement Considerations

No public confirmed substitute part numbers are available. The component is marked as obsolete. Designers should evaluate newer Renesas video PLL families or generic frequency synthesizers that match the voltage, package, and frequency specifications.
