Notes:
1. Power saving alternative to Thevenin termination.
2. Place termination resistors as close to destination inputs as possible.

Figure 5. Parallel Termination (3-Resistor)
LVPECL has high input impedance, and very low output
impedance (open emitter), and small signal swing which
results in low electromagnetic interference (EMI). LVPECL
is ideal for driving 50
and 100
controlled impedance
transmission lines. There are several techniques in
terminating the LVPECL output, which are the Parallel
Termination-Thevenin Equivalent, the Parallel Termination
(3-Resistor), and the AC-Coupled Termination. Unused
output pairs may be left floating. However, single-ended
outputs must be terminated, or balanced.
