PRODUCTION DATA
Use a termination resistor which best matches the differential impedance or your transmission line. The resistor should be between 90 ? and 110 ?. Remember that the current mode outputs need the termination resistor to generate the differential voltage. LVDS will not work correctly without resistor termination. Typically, connecting a single resistor across the pair at the receiver end will suffice.
Surface mount 1% resistors are the best. PCB stubs, component lead, and the distance from the termination to the receiver inputs should be minimized. The distance between the termination resistor and the receiver should be < 10 mm (12 mm MAX).
