LVPECL Output Interface Applications
LVPECL has a high input impedance, a very low
output impedance (open emitter), and a small signal
swing which results in low EMI. LVPECL is ideal for
driving

transmission lines. There are several techniques for
terminating the LVPECL output including: Parallel
Termination-Thevenin
Termination
(3-resistor),
Termination. Unused output pairs may be left
floating. However, single-ended outputs must be
terminated, or balanced.

Power-saving alternative to Thevenin termination.
Place termination resistors as close to destination inputs as
possible.
Rb resistor sets the DC bias voltage, equal to V
