Description
The SL23EP05 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 SL23EP05 is available with two (2) drive strength
versions called -1 and -1H. The -1 is the standard-drive
version and -1H is the high-drive version.
The SL23EP05 high-drive version operates up to 220MHz
and 200MHz at 3.3V and 2.5V power supplies respectively.
The standard drive version -1 operates up to 167MHz and
133MHz at 3.3V and 2.5V respectively.
The SL23EP05 enter into Power Down (PD) mode if the
input at CLKIN is less then 2.0MHz or there is no rising
edge. In this state all five (5) outputs are tri-stated and the
PLL is turned off leading to less than 10 A of power supply
current draw.
Applications
