Termination for 2.5V LVPECL Outputs

Figure 4A and Figure 4B show examples of termination for 2.5V

LVPECL driver. These terminations are equivalent to terminating

Ω 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 4C.
