• Supports specific HDTV frequencies including 74.25 MHz and 74.175824 MHz
• Delivers low jitter performance suitable for sensitive clock generation

Applications

• Set-top boxes
• HDTV receivers

Procurement Notes

Verify the exact ordering suffix against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required frequency standards and voltage levels before procurement. Cross-reference datasheet revisions to confirm pinout and electrical characteristics match system requirements.

Selection Notes

Select this component for applications requiring precise clock synthesis with low jitter in compact form factors. The integrated VCXO functionality reduces external component count. Verify that the supported HDTV frequencies align with target display or receiver standards.

Part Context

This part belongs to Renesas' family of clock generators and frequency synthesizers. It combines VCXO and PLL capabilities in a single IC, targeting consumer electronics where space and cost efficiency are critical while maintaining signal integrity for digital video interfaces.
