Abstract
The ALICE Central Trigger Processor (CTP) is going to be upgraded for LHC Run 3 with com-
pletely new hardware and a new Trigger and Timing Control (TTC-PON) system based on a
Passive Optical Network (PON) system. The new trigger system has been designed as dead time
free and able to transmit trigger data at 9.6 Gbps. A new universal trigger board has been de-
signed, where by changing the FMC card, it can function as a CTP or as a LTU. It is based on
the Xilinx Kintex Ultrascale FPGA and upgraded TTC-PON. The new trigger system and the
prototype of the trigger board will be presented.
