Abstract :
A new electronics for precise clock generation and distribution has been designed for the CBM ToF-wall. The main card (CBM-CLOCK-SYTEM) is based on a frequency synthesizer chip to create two independent output frequencies that are phase coupled. An additionally downstream fast CPLD creates a synchronization signal, which is needed as a periodically epoch marker for the system.
