SL23EP04NZ
Low Jitter and Skew DC to 220 MHz Clock Buffer
Key Features
• DC to 220 MHz operating frequency range
• Low output clock skew: 60ps-typ
• Low part-to-part output skew: 80 ps-typ
• 3.3V to 2.5V operation supply voltage range
• Low power dissipation:
• - 10 mA-typ at 66MHz at VDD=3.3V
• - 9 mA-typ at 66MHz at VDD=2.5V
• One input to four output fanout buffer drivers
• Output Enable (OE) control function
• Available in 8-pin TSSOP package
• Available in Commercial and Industrial grades
• Available in Lead (Pb) free package
Applications
• General Purpose PCI/PCI-X Clock Buffer
• Printers, MFPs and Digital Copiers
• PCs and Work Stations
• Routers, Switchers and Servers
• Datacom and Telecom
• High-Speed Digital Embeded Systems
Description
The SL23EP04NZ is a low skew, jitter and power fanout
buffer designed to produce up to four (4) clock outputs
from one (1) reference input clock, for high speed clock
distribution, including PCI/PCI-X applications.
The SL23EP04NZ products operate from DC to 220MHz.
The only difference between SL23EP04-1 and
SL23EP04NZ-1Z is the OE logic implementation. Refer to
the Available OE Logic Configuration Table. 1
Benefits
• Up to four (4) distribution of input clock
• Low propagation delay
• Low output-to-output skew
• Low output jitter
• Low power dissipation
