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
