The DS110DF410 datasheet references support for Fibre Channel in several places. However, standard Fibre Channel cabling is 150 Ohms and the DS110DF410 uses 100 Ohm termination at both the input and output and doesn't appear to have any ability to disable or change this termination. We would like to use the part in a Fibre Channel application with 150 Ohm cabling. Is there a recommended way to do this?
Our application is operating at 1.0625 Gbps. Using a 25 Ohm series resistor for the each of the two RX inputs would probably make a reasonable approach for a providing 150 RX termination. Placing a 300 ohm resistor in parallel with the 150 ohm characteristic differential impedance output traces should present a 100 ohm impedance to the driver, but would have some impact due to differing from 150 receiver load. Is there a recommended way to address Fibre Channel 150 cables using this part?
