Soft dB Mk3-PLL Open Source SPM Controller & PLL Spec sheet - Manual

Open Source SPM Controller & PLL
Model Mk3-PLL
The Open Source SPM Controller & PLL can be used as:
ü a SPM controller
ü a controller with an embedded PLL, or
ü 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.

of the PLL”
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.
