LOW SKEW, 1-TO-9
DIFFERENTIAL-TO-3.3V LVPECL/ECL FANOUT BUFFER
SCHEMATIC EXAMPLE
This application note provides general design guide using
ICS853111-01 LVPECL buffer. Figure 4 shows a schematic
example of the ICS853111-01 LVPECL clock buffer. In this
example, the input is driven by an LVPECL driver.
