About Transceiver???

If there was a serial digital data stream whose speed was 1Gbps. Can I recovery these datas by transceiver? If I can, how to realize it? And another question, is the transceiver valid for recoverying...

It may be useful to check the GXB transceiver specification in detail.

The GXB clock recovery unit can be configured to tolerate up to 1000 ppm frequency deviation. If this amount is sufficient for your application, the lock time to phase steps is most likely the most serious issue. I didn't find an explicite CRU lock time specification, but it may be estimated from the maximum receiver PLL bandwidth of 60 MHz.
