FEMTOCLOCK CRYSTAL-TO-3.3V, 2.5V LVPECL FREQUENCY SYNTHESIZER
Termination for 2.5V LVPECL Outputs
Figure 5A and Figure 5B show examples of termination for 2.5V
LVPECL driver. These terminations are equivalent to terminating 50
to VCC – 2V. For VCC= 2.5V, the VCC– 2V is very close to ground level.
The R3 in Figure 5B can be eliminated and the termination is shown
in Figure 5C.
