LVPECL Output Termination
LVPECL output has very low output impedance (open
emitter), and small signal swing which results in low
EMI. LVPECL is ideal for driving 50Ω and 100Ω-
controlled impedance transmission lines. There are
several techniques in terminating the LVPECL output,
as shown in Figures 5a and 5b.
