gsm phone calibration

Is there someone who can share some documents about the TCXO and crystal calibration theory for GSM phone? thanks

i hope someone can help me ,thanks

There isn't much theory there. The TCXO needs to be centered after reflow. The implementation detail's vary depending on how you are tuning. Is there a more specific question you have?

i hope i could get some document detail about it , could you help me?

If you have specific questions, then ask them. I'm sure if you have specific questions, then you could get answers.
