Note 1. Power-saving alternative to Thevenin termination.
Note 2. Placeterminationresistorsasclosetodestinationinputsaspossible.
Note 3. Rb resistor sets the DC bias voltage, equal to VT.
For +2.5V systems Rb = 19.
For +3.3V systems Rb = 46 to 50.
Note 4. C1 is an optional bypass capacitor intended to compensate for any
tr/tf mismatches.

Figure 7. Terminating Unused I/O
Note 1. Unused output (/Q) must be terminated to balance the output.
Note 2. For +2.5V systems: R1 = 250, R2 = 62.5, R3 = 1.25k,
R4 = 1.2k.
For +3.3V systems: R1 = 130, R2 = 82, R3 = 1k, R4 = 1.6k.
Note 3. Unused output pairs (Q and /Q) may be left floating.
LVPECL output have 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
in terminating the LVPECL output, as shown in Figures 5
through 7.
