LVPECL Output Interface Applications
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.
