CY2292
Three-PLL General-Purpose
EPROM Programmable Clock Generator
Features
• Three integrated phase-locked loops
• EPROM programmability
• Factory-programmable (CY2292) or field-program-
mable (CY2292F) device options
• Low-skew, low-jitter, high-accuracy outputs
• Power-management options (Shutdown, OE, Suspend)
• Frequency select option
• Smooth slewing on CPUCLK
• Configurable 3.3V or 5V operation
• 16-pin SOIC Package (TSSOP: F only)
Benefits
• Generates up to three custom frequencies from
external sources
• Easy customization and fast turnaround
• Programming support available for all opportunities
• Meets critical industry standard timing requirements
• Supports low-power applications
• Eight user-selectable frequencies on CPU PLL
• Allows downstream PLLs to stay locked on CPUCLK
output
• Enables application compatibility
• Industry-standard packaging saves on board space
