LVPECL Output Interface Applications
LVPECL has high input impedance, very low output
(open emitter) impedance, and small signal swing,
which result in low EMI. LVPECL is ideal for driving
50Ω and 100Ω controlled impedance transmission
lines. There are several techniques for terminating

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.
