In ADF7030-1 data sheet,
EV-ADF70301-868BZ uses TCXO,
EV-ADF70301-915AZ uses XTAL,
and others also have different type of 26 MHz part.
Please advise which type should be chosen in which condition.
Please also advise more documentations regarding this issue.
From UG-957 (ADF7030-1 Hardware Reference Manual),
"Generally a TCXO is used for applications that demand high RF frequency accuracy, such as narrow-band systems where the RF channel width is less than 25 kHz."
TCXO is more accurate than XTAL however, it has higher power consumption since it requires a supply and thus, power needs to be removed from it when the ADF7030-1 is brought to sleep to achieve low power on the board.
You may look into UG-957 and UG-1002 for more details
There's a lot of resources in the internet regarding XTAL vs TCXO such as:
Bottomline is, depending on how much you can relax your RF specs, antenna design, or design considerations(i.e. environment), you can use XTAL for a more cost effective option.
Thanks, guys. very appreciate all quick answers.
