Figure 4. Parallel Termination–Thevenin Equivalent
Notes:
1. For +2.5V systems: R1 = 250Ω, R2 = 62.5Ω
2. For +3.3V systems: R1 = 130Ω, R2 = 83Ω
Figure 5. Three-Resistor “Y–Termination”
Notes:
1. Power-saving alternative to Thevenin termination.
2. Place termination resistors as close to destination inputs as possible.
3. R
resistor sets the DC bias voltage, equal to V
T
.
For +2.5V systems R
b
= 19Ω.
For +3.3V systems R
= 46Ω to 50Ω.
4. C1 is an optional bypass capacitor intended to compensate for any
t

OUTPUT TERMINATION RECOMMENDATIONS
LVPECL outputs have very low output impedance (open
emitter), and small signal swing which results in low EMI
(electro-magnetic interference). The LVPECL is ideal for
driving 50Ω- and 100Ω-controlled impedance transmission
lines. In addition, LVPECL is compatible for driving standard
PECL inputs since PECL inputs require only 100mV input
swing. Further, there are several techniques in terminating
the LVPECL outputs, as shown in Figure 4 through 6.
Figure 6. Terminating Unused I/O
Notes:
1. Unused output (/Q) must be terminated to balance the output.
2. For +2.5V systems: R1 = 250Ω, R2 = 62.5Ω, R3 = 1.25kΩ,
R4 = 1.2kΩ.
For +3.3V systems: R1 = 130Ω, R2 = 82Ω, R3 = 1kΩ, R4 = 1.6kΩ.
3. Unused output pairs (Q and /Q) may be left floating.
