Description
The SL23EP04 is a low skew, low jitter and low power
Zero Delay Buffer (ZDB) designed to produce up to four
(4) clock outputs from one (1) reference input clock, for
high speed clock distribution applications.
The product has an on-chip PLL and a feedback pin
(FBK) which can be used to obtain feedback from any
one of the 4 output clocks. The SL23EP04 offers X/2,1X
and 2X frequency options at the output with respect to
input reference clock. Refer to the “Product Configuration
Table” for the details of these options.
The SL23EP04-1H and -2H High Drive version operates
up to 220 MHz and 200MHz at 3.3 and 2.5V power
supplies respectively. The standard versions -1 and -2
operate up to 167MHz and 135MHz at 3.3V and 2.5V
power supplies respectively with CL=15pF output load.
The SL23EP04 enter into Power Down (PD) mode if the
input at CLKIN is DC (GND to VDD). In this state all 4
output clocks are tri-stated and the PLL is turned off,
leading to 8 A-typ power supply current draw.
Applications
Printers, MFPs and Digital Copiers
PCs and Work Stations
Routers, Switchers and Servers
Datacom and Telecom
High-Speed Digital Embeded Systems
Benefits
Up to four (4) distribution of input clock
Standard and High-Drive levels to control
impedance level, frequency range and EMI
Low skew, jitter and power dissipation
