The 1142-500 TTCcf Clocks Fanout module was designed for the distribution of 40.079 MHz bunch-crossing clocks and 11.2455 kHz orbit signals to electronics equipment such as TTCex and TTCtx transmitters at particle physics experiments at CERN's LHC (Large Hadron Collider). The module comprises two independent 1:9 sections, one of which is normally used for the bunch clock and the other for the orbit clock fanout. Both sections of the TTCcf have DC-coupled ECL inputs and outputs and they can be used interchangeably for either signal.
AC coupling can be used at the bunch clock destinations. For the orbit clock, DC coupling should be maintained from the LHCrx since the signal is unbalanced and has a low repetition rate. The modules can be configured in a tree structure to reduce the cabling required to supply many destinations from a central point. To minimise noise and jitter the TTCcf uses standard 10E ECL and the module draws about 1 A from a -5.2 V power supply.
The TTCcf is a standard 3U 4HP Europa module.The high density of front panel connectors is achieved by the use of special Lemo EPN.00.250.NTN coax connectors which are mounted in pairs on either side of a daughter card that is spaced 5.3 mm from the main pcb. The differential clock drivers are also mounted on both sides of the 4-layer card, which has internal ground and -5.2 V layers.
The TTCcf module was designed by Bruce Taylor and manufactured from 1999 till 2002.
