LCGT Timing System

The LCGT timing system will be a dead copy of the advanced LIGO timing system

Functions

• Provides accurate time information to all the stations in the LCGT.
• The system provides 2^N Hz clock signals synchronized with the GPS seconds.
• The system also distributes the absolute time information to the DAQ hardwares so that

each sample recorded will be unambiguously associated with an absolute GPS second.
