LVDS interconnection
Posted: Mon Oct 20, 2014 11:51 am
Hey,
I have a little trouble in gathering information about how to connect board-to-board by LVDS (GPIO).
I need to connect one parallella 7010 (24 gpio) to another parallella 7010 (24 gpio). by my understanding ,it will leave me with 12 signals.
I'm new to LVDS so I have a noob questions:
1. What is the Bandwidth of that connection?
2. Do I just connect the GPIO pines by pure LVDS cable or do I need to use some kind of LVDS serializer/deserializer ?
As I said I'm new to LVDS, when using single ended I know what to do with the input/output signal. differential gets it's input by GPIOx_N_P.
3. How do I read/write the values while programming the parallella FPGA/Board.
Thanks!
