CMOD225-10-100PLL module
The CMOD225-10-100 is a Phase Locked Loop (PLL) module that phase locks the internal ultra-low phase noise 100 MHz VCXO to an external 10 MHz input frequency reference. If no input reference is detected, the module will automatically lock to its internal 10 MHz TCXO reference. The CMOD225-10-100 has two separate optocouplers to indicate lock status and missing input reference.
