TERMINATION RECOMMENDATIONS
For +2.5V systems: R1 = 250Ω, R2 = 62.5Ω
Power-saving alternative to Thevenin termination.
Place termination resistors as close to destination inputs as possible.
R
Unused output (/Q) must be terminated to balance the output.
Micrel's differential I/O logic devices include a V
Connect unused input through 50Ω to V
For +2.5V systems: R1 = 250Ω, R2 = 62.5Ω.
