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

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