CSIP Level 1 Theory of Operation: Physical Structure
• 4X multiplexer for array data, clock, control signals, and power signals from the NAIM to
transducer connectors or to no connection if no transducer connector is selected
• 3X multiplexer for transducer temperature sensing lines to NAIM and sensors for trans-
ducer 3D position data and plane selection data.
• 3X multiplexer for Motor Controller signals from the NAIM to the transducer
• Signal path from CW/PW connector to the NAIM for CW personality signals
• Decoupling filters for all power supply input buses
• Transducer-disconnect interrupt signal to the NAIM from each transducer connector
• I
2
C interface and flash EEPROM for board-level identification
• Provides a path from the NAIM for VX1, VX2, VX3+, VX3-, HV+, HV-, and DC_BIAS1 volt-
ages to the transducers. Uses VRELAY (+12 V), and SS_+5V power buses.
