Document #: 38-07230 Rev. *C
Revised July 01, 2005
Features
• Spread Aware™—designed to work with SSFTG
reference signals
• Well suited to both 100- and 133-MHz designs
• Ten (CY2509) or eleven (CY2510) LVCMOS/LVTTL
outputs
• 50 ps typical peak cycle-to-cycle jitter
• Single output enable pin for CY2510 version, dual pins
on CY2509 devices allow shutting down a portion of the
outputs
• 3.3V power supply
• On board 25
Ω damping resistors
• Available in 24-pin TSSOP package
• Improved tracking skew, but narrower frequency
support limit when compared to W132-09B/10B
