using stratix II GX transceiver on low data rate..

The specs of startix II GX transceiver development kit says that it can operate from 600Mbps~6Gbps. Does that mean there is no way it can operate on lower speeds like 100Mbps? (Im talking about...

Hi,

If you are talking about transceivers then they must have bit rate restrictions due to CDR circuitry(PLL can only accept a range of input clock frequency). You can prove that by instantiating an LVDS and entering your rates then check the input clock frequency to PLL.

If you are talking about using the lvds pins only then they should accept any data rate up to an allowed maximum. I certainly don't need transceivers for 100 Mbps
