Abstract: An experiment to measure an invariant mass of {\phi} mesons in nuclear medium is planned as the J-PARC E16 experiment. A trigger merging module (TRG-MRG) has been developed to detect leading-edges from 256 channels of discriminator-output signals and transmit those serialized hit data to trigger decision module with four optical links. The result of the test shows enough performance of the TRG-MRG as 1 ns TDC and data multiplexer with four 6.25 Gbps transceivers.<br />Comment: 6 pages, 17 figures, conference record for the 21st IEEE Real Time Conference
