FMC DEL 1ns 4cha
The FMC DEL 1ns 4cha delay module will take in a TTL trigger signal and will send it out to four different outputs. The delay from the trigger input to each of the outputs can be set independently in a range from 600 ns to 120 seconds. It is implemented using a dedicated time-to-digital converter IC from the European company Acam.

Hardware and VHDL design notes published
An engineer-to-engineer note describing the hardware and VHDL design of the Fine Delay has been published. It provides a lot of information on the internals of the FD card, calibration techniques, White Rabbit implementation, Acam’s TDC and programming the card’s registers.
09-01-2013: 70 Fine Delay FMC cards shipped
INCAA Computers in the Netherlands has produced and tested seventy Fine Delay FMC cards. These cards have a resolution better than 1 ns.
15 V3 boards built
A small series of the Fine Delay module board has been built to be used in tests for CNGS to help in measuring precisely the speed of neutrinos. One board will be reserved to be used in a prototype setup for the LHC kicker magnets. It was V3 that has been built, V4 will have a slightly different output stage.
