Primary selector sub matrix unit encoder doublet in triplet in 6 to 2 selector sub matrix unit Selecting highest 2 hits If the same pT, ASIC chooses upper one. Selecting the highest pT hit corresponding to centered one 6 to 2 sel H/L selector H/L Selector H has 1 st priority, pT is 2 nd priority. HHLL=HH HLL=HL LL=LL From HpT From LpT
