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