CMS HCAL TIMING CONTROL MODULE(CCM)

• CCM CLOCK CONTROL MONITOR
• CCM - Three Board Module that resides in the
  CMS HCAL Readout Box(RBX)

Interface between Front End Boards and Main
Control System

CMS HCAL TIMING CONTROL MODULE(CCM)

• CLOCK BOARD FUNCTION
• Receive timing information optically from TTC
  system via the TTCrx.
• Distribute timing information to the Front End
  boards that reside in the RBX using LVPECL
  differential technology.
• CONTROL BOARD FUNCTION
• Interface to Main Control System.
• Distribute control signals to Front End boards
  via RBXbus.
• Control Clock and Monitor boards.
• MONITOR BOARD FUNCTION
• Monitor power supply voltages.
• Monitor temperature of Readout modules.
