3901 North First Street
San Jose
,
CA 95134
408-943-2600
Revised December 22, 2003
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
Low power dissipation:
— 3.3V = 52 mW-typ @ 6MHz
— 3.3V = 60 mW-typ @ 12MHz
— 3.3V = 72 mW-typ @ 24MHz
Low cycle-to cycle jitter:
— 8 MHz = 450 ps-max
— 16 MHz = 225 ps-max
— 32 MHz = 150 ps-max
