	=== VCTCXO ~~tuning~~ ===		=== VCTCXO Tuning ===

	VCTCXO can be tuned by onboard phase detector (IC23, ADF4002) or by DAC (IC22). The onboard phase detector is used to synchronize onboard VCTCXO with external equipment (via J19 U.FL connector) to calibrate frequency error. At the same time only phase detector or DAC can control VCTCXO. DAC and phase detector is controlled by FX3 (USB) and selection between them is done automatically. When board is powered, by default VCTCXO is controlled by DAC.		VCTCXO can be tuned by onboard phase detector (IC23, ADF4002) or by DAC (IC22).

	VCTCXO can be tuned by onboard phase detector (IC23, ADF4002) or by DAC (IC22). If phase detector is configured from LimeSuiteGUI software, then DAC is disabled automatically and VCTCXO tuning voltage is supplied from phase detector. When phase detector controls VCTCXO, FPGA2 LED indicates its lock state: red – not locked, green – locked.		VCTCXO can be tuned by onboard phase detector (IC23, ADF4002) or by DAC (IC22).

	VCTCXO can be tuned by onboard frequency synthesizer (IC16, ADF4002) or by DAC (IC15).

	=== VCTCXO ~~calibration procedure~~ ===		=== VCTCXO Calibration Procedure ===

	Board has VCTCXO DAC factory calibration value that is stored in non-volatile memory. This value is loaded to DAC output after each board power up or reset. This value can be changed manually or by automatic calibration procedure. To perform automatic calibration procedure, connect external reference clock to connector J19, start it from LimeSuiteGUI software and enter Fref frequency (default Fref value 10MHz).
