Cypress Semiconductor Corporation • 3901 North First Street • San Jose, CA 95134 • 408-943-2600
Document #: 38-07112 Rev. *E Revised June 03, 2004
Features
• 4- to 32-MHz input frequency range
• 4- to 128-MHz output frequency range
• Accepts clock, crystal, and resonator inputs
• 1x, 2x, and 4x frequency multiplication:
— CY25811: 1x; CY25812: 2x; CY25814: 4x
• Center and down spread modulation
