Functional Description
The Instrument backplane (IB) board distributes the cryostat signals on the 3 or 5 MDM connectors to the circuit boards in the chassis. There are series load resistors for sq1_bias, ssa_fb, sq2_bias, sq2_fb, sq1_fb on the IB card.
There are two different types of IB cards to support 3-MDM or 5-MDM MCE crates.
The 5-MDM circuit board contains nine 96 pin 2mm connectors. Only eight connectors are used as the Clock Card connector has no analog signals. The backplane has 5 gold dot areas for mating to Delphi gold dot flex circuits (MCEv1) or 5 Hirose connectors (MCEv2). The 5 flex sections or Hirose connectors go to 5 pcb-mounted 100 pin MDM connectors.
Some spare signals are connected between the MDM connectors and the Instrument Backplane. These terminate at surface mount pads on the backplane.
