Document Number: 38-07449 Rev. *M Revised December 7, 2017
Three-PLL General -Purpose EPROM- Programmable Clo ck Generator
Features
■ Three integrated phase locked loops (PLLs)
■ Erasable programmable read only memory (EPROM)
programmability
■ Factory programmable (CY2292) or field programmable
(CY2292F) device options
■ Low-skew, low-jitter, high accuracy outputs
■ Power management options (shutdown, OE, suspend)
■ Frequency select option
■ Smooth slewing on CPUCLK
■ Configurable 3.3 V or 5 V operation
■ 16-pin small-outline integrated circuit (SOIC) package
(CY2292F also in TSSOP)
Benefits
■ Generates up to three custom frequencies from one external
source
■ Easy customization and fast turnaround
■ Programming support available for all opportunities
■ Supports low power applications
■ Eight user selectable frequencies on CPU PLL
■ Allows downstream PLLs to stay locked on CPUCLK output
■ Industry standard packaging saves on board space
