This file describes the Master Clock Signals that flow from the two Helper-SCL SFO's to the three Helper Functions: L1_FW_Helper, SCL_Helper, L2_FW_Helper ------------------------------------------------------------------ Original Rev. 14-SEP-1999 Current Rev, 2-AUG-2001 SF0 "A" Connected to a 26 Pin Connector in Rear_PB Location J3 pin 1 to pin 13 ----------------------------------------- Thus this maps to the following MSA_Inputs Depending on which 34 pin Rear-PB Connector You Use. Assuming SFO pins 19,20 Tied to Rear_PB connector pins 31,32 i.e. Standard SF0 1,2 to Rear_PB 13,14 Pin Nums -------------------------- SFO Sequencer Time on the 34 at P2 at P3 Channel Line Selected by pin Rear_PB ---------- ------------- Number this SFO Channel connectors J2 J3 J4 J5 J2 J3 J4 J5 ------- ------------------------- ----------- -- -- -- -- -- -- --- --- Clk not feed to Helpers 3,4 23 87 3 TL_8 SCL Tick Clock 7,8 25 89 2 TL_3 Interaction Marker 11,12 26 91 1 TL_2 Beginning Turn Marker 15,16 29 93 0 TL_7 FW Helper Clock 19,20 31 95 All this assumes SFO pins 19,20 tied to Rear_PB connector pins 31,32 i.e. SF0 1,2 to Rear_PB 13,14. Note: By installing 2 Trompeter connectors on one of our CARMEN_PB's we could then use this SFO to feed 53 MHz to the SCL Hub-End and via this SFO's Channel 3 we could feed SCL Tick Clock to the SCL Hub-End. SF0 "B" Connected to a 26 Pin Connector in Rear_PB Location J5 pin 1 to pin 1 ----------------------------------------- Thus this maps to the following MSA_Inputs Depending on which 34 pin Rear-PB Connector You Use Standard (assuming pin 1 to pin 1) Pin Nums -------------------------- SFO Sequencer Time on the 34 at P2 at P3 Channel Line Selected by pin Rear_PB ---------- ------------- Number this SFO Channel connectors J2 J3 J4 J5 J2 J3 J4 J5 ------- ------------------------- ----------- -- -- -- -- -- -- --- --- Clk not feed to Helpers 3,4 49 113 3 TL_7 FW Helper Clock 7,8 51 115 2 TL_6 Spare Marker 11,12 53 117 1 TL_5 Sync Gap Marker 15,16 55 119 0 TL_4 Cosmic Gap Marker 19,20 57 121 The L1_FW_Helper and L2_FW_Helper will connect to Master Clock through a Rear_PB on their P2. These Master Clock connections will wipe out MSA_Inputs 31:16 and 63:48. This leaves MSA_Inputs 15:0 and 47:32 that these two Helper Functions can use to get additional inputs. The SCL_Helper will connect to the Master Clock through a Rear_PB on its P3. These Master Clock Connections will wipe out MSA_Inputs 95:80 and 127:112. This leaves MSA_Inputs 79:64 and 111:96 that the SCL Helper can use to get additional inputs. Of these inputs the prefered ones to use are 79:71 (9 inputs from Rear_PB connector J2) and 103:101 (3 inputs from Rear_PB connector J4). An FM Card is used to implement the L1 FW Helper. The L1 FW Helper connects via its P2 Paddle Board J5 to SFO Helper "B". As installed this is done via the cable labeled "SF8 P4". The same FM Card is used for the SCL Helper. The SCL Helper connects via its P3 Paddle Board J3 to SFO Helper "A". As installed this is done via the cable labeled "SF8 P6". The SCL Helper connects via its P3 Paddle Board J5 to SFO Helper "B". As installed this is done via the cable labeled "SF8 P5". An FM Card is used to implement the L2 FW Helper. The following is a list of the Input Signals to the L2 Helper. The Input Signals that come from the Master Clock are marked with a "*". Name MSA_In Comment ------------------------------- ------ ---------------- L2_Busy_Answer_Delay(0) 16 L2_Busy_Answer_Delay(1) 17 no connection 19 Global Clock net * Live_Crossing 21 L1_STF_FIFO_Not_Empty 23 L2_Ans_FIFO_Not_Empty 25 Transfer_to_L3_Required 27 L2_Capture_Monitor_Data_Request 29 L2_Global_Answer_Strobe 31 * Helper_Clock 51 Global Clock net The L2 Helper gets Live_Crossing i.e. CMC Time Line 3 from the Helper "A" Selector Fanout. This signal comes from Ch#2 of this SFO and is thus on the 6th pair of a long 26 conductor cable that runs from the Carmen_PB over to a couple of inches from the L2_Helper's P2 Rear_PB. Here there is a short single signal twisted pair that connects the 6th pair in the 26 conductor cable to pins 11&12 on connector J3 of the P2 Rear_PB i.e. MAS_In_21. The L2 Helper gets Helper Tick Clock i.e. CMC Time Line 7 from the Helper "A" Selector Fanout. This signal comes from CH#0 of this SFO and is thus on the 10 pair of a long 26 conductor cable that runs from the Carmen_PB over to a couple of inches from the L2_Helper's P2 Rear_PB. Here there is a short single signal twister pair that connects the 10th pair of the 26 conductor cable to pins 7&8 on connector J5 of the P2 Rear_PB, i.e. MSA_In_51 At the L2_Helper end of the long 26 conductor cable from the Helper "A" SFO there are terminator rresistors on the 2nd, 4th, 8th pairs of this cable to terminate the selected_Clock. CH#1 and CH#3 signals.

We need 6 signals so we clearly need 2 SFO modules. But it would be nice to setup these 2 SFO's so that the "extra" copies of the signals that they select are not arranged in some horible way that makes them into pure slag.

Recall also that the L1_FW_Helper and the L2_FW_Helper will use the FW_Helper Clock signal and must receive this on MSA_Input_51 which is pins 7,8 of the 34 pin connector on the Rear-PB and that the SCL_Helper needs to use the FW_Tick_CLk as its clock signal and that it must receive this signal on MSA_Input_95 which is pins 31,32 of a Rear-PB. So we will need 2 SFO's to feed all these signals from the Master Clock to the 3 Helper Functions.
