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

Place the capacitor on the component side of the PCB as close to the VDD pin as possible. The PCB trace to the VDD pin and to the GND via should be kept as short as possible. Do not use vias between the decoupling capacitor and the VDD pin. Package Outline and Package Dimensions
