# # Distributed ByPass Capacitor Comps # # Key In Components File for the # HUB-0 ATLAS L1Calo Hub Module # ---=====----------------------------- # # Original Rev. 20-Jan-2016 # Most Recent Rev. 9-Nov-2016 # # # This file holds all of the "Distributed" bypass capacitors. # # These are the bypass capacitors that are placed # opportunistically during routing or that are placed # because during routing it looks like the circuit could # benefit from an additional bypass capacitor, e.g. for # symmetry of the layout. # # These bypass capacitors can be on any of the power nets. # # # # Neither the: SWCH_1V2 (DCDC5) or the # FAN_1V8 (DCDC7) or the # BULK_3V3 (DCDC8) # # converters have large Tantalum capacitors as part of # their Output Filters in their main comps and nets files. # # All of the other DCDC Converters pick up Output Filter # Tantalum Capacitors as part of their supply to the FPGA. # # So here place some large Tantalum capacitors for each # of these 3 supplies. Note that BULK_3V3 must use # the 330 uFd 6.3V "V" case T520 part and the two lower # voltage converters use the similar 470 uFd 2.5V part. # # # For the SWCH_1V2 converter. # C251 Cap_470_uFd_Tant_V SY_JUNK Tant_V_Case 69.00 44.00 2 0 C252 Cap_470_uFd_Tant_V SY_JUNK Tant_V_Case 119.00 44.00 2 0 C267 Cap_470_uFd_Tant_V SY_JUNK Tant_V_Case 168.00 37.60 2 0 C269 Cap_10_uFd_10_V_0805 SY_JUNK cap_0805 51.00 48.00 2 0 C270 Cap_10_uFd_10_V_0805 SY_JUNK cap_0805 102.00 45.00 2 0 C271 Cap_10_uFd_10_V_0805 SY_JUNK cap_0805 180.00 43.10 2 0 # # For the FAN_1V8 converter. # C253 Cap_470_uFd_Tant_V SY_JUNK Tant_V_Case 251.00 207.50 1 90 C254 Cap_470_uFd_Tant_V SY_JUNK Tant_V_Case 212.50 196.00 2 180 C255 Cap_470_uFd_Tant_V SY_JUNK Tant_V_Case 253.50 170.50 1 270 C256 Cap_470_uFd_Tant_V SY_JUNK Tant_V_Case 209.50 72.30 2 0 C259 Cap_10_uFd_10_V_0805 SY_JUNK cap_0805 252.10 188.70 2 180 C260 Cap_10_uFd_10_V_0805 SY_JUNK cap_0805 217.60 187.70 2 180 C261 Cap_10_uFd_10_V_0805 SY_JUNK cap_0805 215.60 189.20 1 180 C262 Cap_10_uFd_10_V_0805 SY_JUNK cap_0805 232.00 71.20 1 0 C263 Cap_2.2_uFd_0603 SY_JUNK cap_0603 254.40 192.60 2 180 C264 Cap_2.2_uFd_0603 SY_JUNK cap_0603 255.50 185.50 1 0 C265 Cap_2.2_uFd_0603 SY_JUNK cap_0603 242.70 172.40 1 180 C266 Cap_2.2_uFd_0603 SY_JUNK cap_0603 242.70 159.80 1 180 C277 Cap_2.2_uFd_0603 SY_JUNK cap_0603 242.70 84.20 1 180 C278 Cap_2.2_uFd_0603 SY_JUNK cap_0603 226.00 70.90 2 180 # # For the BULK_3V3 converter. # C257 Cap_330_uFd_Tant_V SY_JUNK Tant_V_Case 202.00 305.00 2 0 C258 Cap_330_uFd_Tant_V SY_JUNK Tant_V_Case 135.50 44.00 2 0 C268 Cap_330_uFd_Tant_V SY_JUNK Tant_V_Case 50.00 44.00 2 0 C279 Cap_330_uFd_Tant_V SY_JUNK Tant_V_Case 51.60 232.50 2 90 C272 Cap_10_uFd_10_V_0805 SY_JUNK cap_0805 205.00 313.00 2 0 C273 Cap_2.2_uFd_0603 SY_JUNK cap_0603 189.00 313.00 2 0 # # For the BULK_1V8 converter. # C274 Cap_10_uFd_10_V_0805 SY_JUNK cap_0805 197.00 313.00 2 0 C275 Cap_2.2_uFd_0603 SY_JUNK cap_0603 181.00 313.00 2 0 C276 Cap_470_uFd_Tant_V SY_JUNK Tant_V_Case 202.00 298.00 2 0
