Hi all.Did any body try to connect altera LVDS i/o to sub-LVDS i/o standard device? What adaptation did you use? Thanks in advance
I'm planning to connect a sensor via Sub-LVDS interface to an Arria 10 FPGA. Just a receiver is needed.
Has anyone had experience with it?
When looking in the device datasheet Arria 10 supports only LVDS. But the voltage levels are similar to Cyclone 5 devices
which supports both LVDS and Sub-LVDS.
The Sub-LVDS interface of the sensor provides a common mode voltage of 0.9V, the differential output voltage is 150 mV.
It looks like it works with Arria 10 for data rates below 700 Mbps. But it is not clear what is the minimum VID when VCM = 0.9V?
The question is can Arria 10 used as a Sub-LVDS receiver?
Where are the differences between Cyclone 5 Sub-LVDS and Arria 10 LVDS interface (accept the data rate limitation)?
