GTH / GTX tranceiver compatibility

Hi,

 

I'm interested in interfacing a Virtex-6 GTH transceiver operating at 3Gbps (PLL div=4) with a Virtex-5 GTX transceiver. I don't see any reason they shouldn't interoperate, but I don't see explicit mention that they will, either. Will these two transceivers play nice with each other?

 

Thanks,

Nick

Yes, they will play nice with each other and with any other transceiver operating at 3 Gbps and AC coupled.

• 2.48 Gb/s to 2.795 Gb/s
• 4.96 Gb/s to 5.591 Gb/s

If you need to transmit 3.0 Gb/s then it is not possible to interface with GTH as this line rate is not supported.  You must use line rates that are compatible between both ends of the link.
