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

• 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

• Available in 8-pin SOIC and TSSOP packages

• Commercial and industrial temperature ranges
