abstract = {{We developed a MicroTCA.4 (MTCA.4) module to generate and distribute trigger timing signals. This module has 16 LVDS inputs and 16 LVDS outputs each on the front panel and the Zone 3 connector, and 8 M-LVDS I/O’s for MTCA.4 backplane. The trigger timing of each output can be precisely adjusted with the interval of 238 MHz or 509 MHz clocks by a 24-bit counter. The timing can also be fine-tuned by ~80 ps tap delay. This module has additional 5 optical transceivers, one for receiving trigger signals from upstream and four for fanouts to downstream. A master module distributes trigger signals, trigger counts, and event data through optical links. Slave modules generate trigger output signals with appropriate delays based on the event data and the local setting for each output channel. The timing jitter was measured to be 40 ps std, which is significantly smaller than the clock period of 238 MHz or 509 MHz. This system can also distribute an alarm signal received by a slave module to take data at a faulty situation. Trigger systems with this module have been utilized in SPring-8, SACLA, and NewSUBARU and stably synchronize various accelerator components with sufficient timing accuracy.}},
