# # Combined Data (TTC + ROD Back-Channel Data) Distribution # # Hub Module Key In Components File # ------------------------------------- # # # Original Rev. 16-Apr-2015 # Most Recent Rev. 28-Oct-2016 # # # This Comps file holds all of the components for the # Combined Data Distribution. # # The Combined Data is the data that arrives on the TCC # plus any ROD Back-Channel data aka the ROD Readout Control. # # The Combined Data is distributed to all 12 FEX Cards # to the Other Hub Module, and to the ROD on This Hub # where it is called just "TTC" in Ed's MegArray pinout # document. # # The Combined Data is distributed as a Xilinx MGT serial link. # # It is distributed on ATCA Port 1 Tx. # # # # # The AC Coupling capacitors for the Combined Data # MGT links are located on the Hub Module, i.e. at # the sending end of the link. These Combined Data # links run to the 12 FEX Cards, to the Other Hub # and to the ROD on This Hub. # # Combined Data Caps to: # # to ROD: C1697, C1698 # # to FEX_14: C1695, C1696 # ... ... ... # # to FEX_08: C1683, C1684 # ... ... ... # # to FEX_03: C1673, C1674 # # Other Hub: C1671, C1672 # # # # For now the Combined Data Coupling Caps to the ROD # are just placed at the top of the stackof coupling # caps for Combined Data to the Backplane. # # Initially all of these caps were in a vertical column. # # - Initially the center of this vertical column was # at about a Y of 124.1 mm i.e. FEX_08 C1683, C1684, # to be about in the center. # # 12-Apr-16 the center of the column was moved up to # Y of 130.00 mm. # # Y deltas 1.0 mm between the capacitors in a diff pair # 3.4 mm unit cell # # Note that this allows a Ground Rivet between # capacitor pairs. # # During routing it became clear that the one column # scheme would not work and the Combined Data # AC Coupling capacitors were moved to various # locations on the back side of the Hub card. # # # to ROD on This Hub # C1698 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 153.50 183.90 2 180 C1697 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 153.50 184.90 2 180 # to FEX_14 C1696 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 154.00 176.40 2 180 C1695 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 154.00 175.40 2 180 # to FEX_13 C1694 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 158.00 174.40 2 180 C1693 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 158.00 173.40 2 180 # to FEX_12 C1692 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 162.00 172.40 2 180 C1691 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 162.00 171.40 2 180 # to FEX_11 C1690 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 163.00 160.10 2 180 C1689 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 163.00 159.10 2 180 # to FEX_10 C1688 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 159.00 158.10 2 180 C1687 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 159.00 157.10 2 180 # to FEX_09 C1686 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 163.00 156.10 2 180 C1685 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 163.00 155.10 2 180 # to FEX_08 C1684 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 173.00 128.10 2 180 C1683 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 173.00 127.10 2 180 # to FEX_07 C1682 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 177.00 126.00 2 180 C1681 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 177.00 125.00 2 180 # to FEX_06 C1680 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 175.00 111.70 2 180 C1679 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 175.00 110.70 2 180 # to FEX_05 C1678 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 171.00 109.50 2 180 C1677 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 171.00 108.50 2 180 # to FEX_04 C1676 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 175.00 103.70 2 180 C1675 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 175.00 102.70 2 180 # to FEX_03 C1674 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 167.00 101.70 2 180 C1673 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 167.00 100.70 2 180 # to Other HUB C1672 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 171.00 99.70 2 180 C1671 Cap_100_nFd_0201 SY_JUNK cap_0201_bot 171.00 98.70 2 180
