CY2509 Datasheet, PDF (1/6 Pages) Cypress Semiconductor – Spread Aware, Ten/Eleven Output Zero Delay Buffer

9/10
CY2509/10
Spread Aware™, Ten/Eleven Output Zero Delay Buffer
Features
• Spread Aware^TM—designed to work with SSFTG refer-
ence signals
• Well suited to both 100- and 133-MHz designs
• Ten (CY2509) or eleven (CY2510) LVCMOS/LVTTL
outputs
• 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 25Ω damping resistors
• Available in 24-pin TSSOP package
• Improved tracking skew, but narrower frequency sup-
port limit when compared to W132-09B/10B
