Description
The SL23EP05 is a low skew, low jitter, and low power Zero Delay Buffer
(ZDB) designed to produce up to five clock outputs from one 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 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 220 MHz and 180 MHz at
3.3 V and 2.5 V power supplies, respectively. The standard drive version –1
operates up to 200 MHz and 167 MHz at 3.3 V and 2.5 V, respectively.
The SL23EP05 enter into Power Down (PD) mode if the input at CLKIN is
less then 2.0 MHz or there is no rising edge. In this state all five outputs are
tri-stated and the PLL is turned off leading to less than 10 A of power
supply current draw.
