Hi all,I have a request where I need to drive two different LVDS 7:1 displays (different resolutions/frequencies/data rates) over the same LVDS interface using the same FPGA design. Which display is used is SW programmable. Can I use altlvds_tx with internal PLL, generated with the datarate settings for the faster display, and hope that the slower will work too since they both use serialization factor 7? Or do I have to use external PLL and then reprogram it with new settings depending on which display is used? Or is there a way to reprogram ALTLVDS_TX with the new datarate? Thank you.
