How to receive slow bit stream data using GXB

Hi, Is there a way to use the GXB in Stratix IV to recover data/clock from a bit stream slower than 600Mbps? I know Xilinx transceivers can do this using oversampling. Thanks, Hua

Hi Dave,

Thank you for your reply. You are right, Xilinx only do data in this scenario. We have a product using this feature from Xilinx right now, I don't know the details but Xilinx transceiver picks the sample point close to the middle automatically based on statistics.

Do you mind point me to the Altera documentation you mentioned about using over-sampling to receive data? Is the phase picking process automated on Altera side?

Thanks,

Hua
