TERMINATION FOR 2.5V LVPECL OUTPUTS
Figure 6A and Figure 6B show examples of termination for 2.5V
LVPECL driver. These terminations are equivalent to terminating
50Ω to V - 2V. For V = 2.5V, the V - 2V is very close to ground

level. The R3 in Figure 6B can be eliminated and the termination
is shown in Figure 6C.
