Termination Recommendations
Figure 1. Parallel Termination- Thevenin Equivalent
Note:
For 2.5V systems: R1= 250Ω, R2= 62.5Ω
Figure 2. 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
. For 3.3V systems R
=50Ω.

Figure 3. Terminating Unused I/O
Notes:
1. Unused output (/Q) must be terminated to balance the output.
2. Micrel’s differential I/O logic devices include a V
reference pin.
BB
3. Connect unused input through 50Ω to V
. Bypass with a 0.01µF capacitor to V
, not GND.
