# # CMX Backplane Connector #4 Net-to-Pin File # ------------------------------------------------ # # # Original Rev. 07-Sep-2011 # Rev: 11-Apr-2012 (added backplane linear rank "bxxx") # Rev: 06-Sep-2011 remove the linear rank and add comments # Most Recent Rev: 22-July-2013 Until now the pins have # been connected to the GROUND net. Now # connect them to the REAR_CG_GND net. # There are 6 of the pins in connector J4. # # # # # This is the N2P file for Backplane Connector #4 on the CMX card. # This is a 2mm hard metric 5 Column x 19 Row type "B-19" connector # with ground shield. # # This is connector J4 in the CMX card design. # # 'Pxx_yy' are the single ended signals (series terminated at the source) # coming from the JEM or CPM Processor cards in the crate # There are (up to) 16 Processor cards in a crate and xx = 0 to 15 # Each Processor sends 25 signals to the CMX card and yy = 0 to 24 # # 'M_zz_POS' and 'M_zz_NEG' are the LVDS signal used for Cable IO # from a Crate CMX card to a System CMX card. 'M_zz_POS' is the # non-inverted signal and 'M_zz_NEG' is the inverted signal. # There are up to 3 cables used for a given CMX card. # A Crate CMX card uses one cable as output only, while a System CMX # card receives 2 or 3 cables as input. # A Rear Transition Module (RTM) card provides the interface to the # three 34-signal LVDS connectors. # Only 27 signals from each connector are routed on the current RTM cards. # zz=0 to 26 correspond to the first cable, # zz=27 to 53 correspond to the second cable, and # zz=54 to 80 correspond to the third cable. # Additionally, 3 more sets of signals are labelled on the backplane # but are not routed on the RTM: zz= 31 to 83 # NET 'P4_19' J4-A1 NET 'GROUND' J4-B1 NET 'P5_18' J4-C1 NET 'P6_18' J4-D1 NET 'P7_18' J4-E1 NET 'P4_20' J4-A2 NET 'P5_19' J4-B2 NET 'P6_19' J4-C2 NET 'GROUND' J4-D2 NET 'P7_19' J4-E2 NET 'P4_21' J4-A3 NET 'GROUND' J4-B3 NET 'P5_20' J4-C3 NET 'P6_20' J4-D3 NET 'P7_20' J4-E3 NET 'P4_22' J4-A4 NET 'P5_21' J4-B4 NET 'P6_21' J4-C4 NET 'GROUND' J4-D4 NET 'P7_21' J4-E4 NET 'P4_23' J4-A5 NET 'GROUND' J4-B5 NET 'P5_22' J4-C5 NET 'P6_22' J4-D5 NET 'P7_22' J4-E5 NET 'P4_24' J4-A6 NET 'P5_23' J4-B6 NET 'P6_23' J4-C6 NET 'GROUND' J4-D6 NET 'P7_23' J4-E6 NET 'GROUND' J4-A7 NET 'GROUND' J4-B7 NET 'P5_24' J4-C7 NET 'P6_24' J4-D7 NET 'P7_24' J4-E7 NET 'M_00_POS' J4-A8 NET 'M_01_POS' J4-B8 NET 'M_02_POS' J4-C8 NET 'M_03_POS' J4-D8 NET 'M_04_POS' J4-E8 NET 'M_00_NEG' J4-A9 NET 'M_01_NEG' J4-B9 NET 'M_02_NEG' J4-C9 NET 'M_03_NEG' J4-D9 NET 'M_04_NEG' J4-E9 NET 'M_05_POS' J4-A10 NET 'M_06_POS' J4-B10 NET 'M_07_POS' J4-C10 NET 'REAR_CG_GND' J4-D10 # this is a cable ground NET 'M_08_POS' J4-E10 NET 'M_05_NEG' J4-A11 NET 'M_06_NEG' J4-B11 NET 'M_07_NEG' J4-C11 NET 'REAR_CG_GND' J4-D11 # this is a cable ground NET 'M_08_NEG' J4-E11 NET 'M_09_POS' J4-A12 NET 'M_10_POS' J4-B12 NET 'M_11_POS' J4-C12 NET 'M_12_POS' J4-D12 NET 'M_13_POS' J4-E12 NET 'M_09_NEG' J4-A13 NET 'M_10_NEG' J4-B13 NET 'M_11_NEG' J4-C13 NET 'M_12_NEG' J4-D13 NET 'M_13_NEG' J4-E13 NET 'M_14_POS' J4-A14 NET 'REAR_CG_GND' J4-B14 # this is a cable ground NET 'M_15_POS' J4-C14 NET 'M_16_POS' J4-D14 NET 'M_17_POS' J4-E14 NET 'M_14_NEG' J4-A15 NET 'REAR_CG_GND' J4-B15 # this is a cable ground NET 'M_15_NEG' J4-C15 NET 'M_16_NEG' J4-D15 NET 'M_17_NEG' J4-E15 NET 'M_18_POS' J4-A16 NET 'M_19_POS' J4-B16 NET 'M_20_POS' J4-C16 NET 'M_21_POS' J4-D16 NET 'M_22_POS' J4-E16 NET 'M_18_NEG' J4-A17 NET 'M_19_NEG' J4-B17 NET 'M_20_NEG' J4-C17 NET 'M_21_NEG' J4-D17 NET 'M_22_NEG' J4-E17 NET 'M_23_POS' J4-A18 NET 'M_24_POS' J4-B18 NET 'M_25_POS' J4-C18 NET 'REAR_CG_GND' J4-D18 # this is a cable ground NET 'M_26_POS' J4-E18 NET 'M_23_NEG' J4-A19 NET 'M_24_NEG' J4-B19 NET 'M_25_NEG' J4-C19 NET 'REAR_CG_GND' J4-D19 # this is a cable ground NET 'M_26_NEG' J4-E19 NET 'GROUND' J4-F1 NET 'GROUND' J4-F3 NET 'GROUND' J4-F5 NET 'GROUND' J4-F7 NET 'GROUND' J4-F9 NET 'GROUND' J4-F11 NET 'GROUND' J4-F13 NET 'GROUND' J4-F15 NET 'GROUND' J4-F17 NET 'GROUND' J4-F19
