Description
The SL2305 is a low skew, low jitter and low power Zero
Delay Buffer (ZDB) designed to produce up to five (5) clock
outputs from one (1) reference input clock for high speed
clock distribution applications. The product has an on-chip
PLL which locks to the input clock at CLKIN and receives its
feedback internally from the CLKOUT pin.
The SL2305 is available with two (2) drive strength versions.
The -1 is the standard-drive version and -1H is the high-
drive version.
The SL2305 high-drive version operates up to 140MHz and
the standard drive version -1 operates up to 100.
The SL2305 enter into Power-Down (PD) mode if the input
at CLKIN is DC (0 to VDD). In this power-down state all five
(5) outputs are tri-stated and the PLL is turned off leading to
less than 12 A-max of power supply current draw.
Applications
Printers and MFPs
Digital Copiers
PCs and Work Stations
DTV
Routers, Switchers and Servers
Digital Embeded Systems
Benefits
Up to five (5) distribution of input clock
Standard and High-Dirive levels to control impedance
level, frequency range and EMI
Low jitter and skew
Low power dissipation
Low cost
