Honored ContributorStratix GX transceiver usage.
As described in new stratix IV device datasheet, the rate of transceiver can support data rate between 600Mbps and 8.5Gbps, I wonder what's the refrence clock frequency? and what's the resolution of...

Honored ContributorThanks , RedSavina!
The most important reason that I plan to use x2 8.5Gbps(actually, 2 times of 3.75G)transceivers to carry 10Gbps traffic is I want to use lesser transceivers. For example, I use StratixIV with 8 transceivers to implement 40Gbps capacity packet processor, etc. If it is reasonable that I used x2 7.5Gbps transceivers rather than x4 3.75Gbps transceivers? Another thinking, if I want to implement 50Gbps capacity packet processor, I use device with 16 transceivers, each group of x3 6.375Gbps transceivers will carry 10Gbps traffic, does it mean we can combine any number of transceivers(x2, x3, x4.....) to carry higher bandwidth traffic?
