I am using a MAX 10 to drive another chip using LVDS. I am using the true LVDS driver. I would like tobe able to Tri-State the LVDS driver when the power to the chip that I am driving is not enabled. If I use BLVDS, will I need to use any external resistors?

Refer to AN-522 - "Implementing Bus LVDS Interface in Supported Altera Device Families".
Yes - this suggests the use of series termination resistors as well as termination resistors for each end of the bus. For MAX 10 use the "GPIO Lite IP" core. Cheers, Alex- Mark as New

In a first step I would check if the LVDS receiver has any problems with LVDS input being driven while the device is unpowered.
Any LVDS receiver or complex chip with LVDS inputs that I know won't. You might be solving a non-existing problem.
