ALTGX transceiver operates in Lock-to-Reference mode?

Hi, Can the ALTGX transceiver be succesfully operated in lock-to-reference mode? Or does it have to be switched into lock-to-data mode before data can be recovered?

Certainly you can operate the transceiver in LTR mode. As I mentioned, oversampling in one instance where you want to do this.

However, in your case you have the problem that you stated. You can lock to the refernce clock and be sure that your frequency is correct but your phase may not (and most likely will not) match the phase of the data. I don't know the altgx transceiver well enough to know if you have some manual method available for then changing the sampling phase of the receiver.
