... Stub Length: Stub lengths should be kept to a minimum. The typical tran- sition time of the DS92CK16 BLVDS output is 0.75ns (20% to 80%). The 100 percent time is 0.75/0.6 or 1.25ns. For a general approximation, if the electrical length of a trace is greater than 1/5 of the transition edge, then the trace is con- sidered a transmission line ...

Applications Information Termination: Use a resistor which best matches the differential impedance of your loaded transmission line. Remember that the current mode outputs need the termination resistor to generate the differential voltage. BLVDS will not work without resistor ter- mination. ...
