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 V
CC – 2V. For VCC = 2.5V, the VCC – 2V is very close to
ground level. The R3 in Figure 4B can be eliminated and the
termination is shown in Figure 5C.
