LOW SKEW, 1-TO-10, DIFFERENTIAL-TO-LVPECL/ECL FANOUT BUFFER

SCHEMATIC EXAMPLE

This application note provides general design guide using

ICS853111A LVPECL buffer. Figure 7 shows a schematic

example of the ICS853111A LVPECL clock buffer. In this

example, the input is driven by an LVPECL driver. CLK_SEL is

set at logic low to select PCLK0/nPCLK0 input.
