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.
