CMOD225-10-100 PLL Module

Crystek's CMOD225-10-100 is a 10 MHz to 100 MHz frequency translation, jitter attenuator

Image of Crystek's CMOD225-10-100 PLL ModuleCrystek's CMOD225-10-100 is a phase-locked loop (PLL) module that phase locks an internal ultra-low phase noise 100 MHz VCXO to an external 10 MHz input frequency reference. If no input reference is detected, the module locks to its internal 10 MHz TCXO reference automatically. The CMOD225-10-100 has two separate optocouplers to indicate lock condition and lack of input reference.
