Features
• Spread Spectrum, VCXO, and Frequency Select
• Input frequency range:
— Crystal: 8–30 MHz
— CLKIN: 0.5–100 MHz
• Output frequency:
— LVCMOS: 1–200 MHz
• Integrated phase-locked loop
• Low jitter, high accuracy outputs
• 3.3V operation
• 8-pin SOIC package
Benefits
• Make inventory of only one device, CY22800, to use in
various applications such as HDTV, STB, DVDR, etc.
• Multiple predefined configurations that can be programmed
into a single chip
• Eliminates the need for expensive and difficult to use
higher-order crystal
• High-performance PLL tailored for multiple applications
• Meets critical timing requirements in complex system
designs
• Enables application compatibility
• Allows up to three different frequency selects
