Open Source SPM Controller & PLL

Model Mk3-PLL

The Open Source SPM Controller & PLL can be used as:

a SPM controller

a controller with an embedded PLL, or

a stand alone PLL

This MK3-PLL model is fully compatible with the SPM control software

developed by the GXSM Group. This model has more computational power and

memory than the MK2-A810 model for further developments and improvements

of the next generation of the GXSM control code.

One of the great innovation of this model is an embedded PLL function.

KEY FEATURES OF THE PLL MODULE

This highly optimized software PLL module is based on an innovative

phase/amplitude detector. This module is embedded in the SPM controller

firmware code.

The analog I/O board of this SPM controller Mk3-PLL model also includes a TCXO (temperature compensated crystal

oscillator), which greatly improves the PLL’s thermal stability and reduces its noise at low frequencies.
