CSIP Level 1 Theory of Operation: Physical Structure
Neo Analog Interface Module (NAIM
• Monitors system temperature, voltage, and beamformer pulser power consumption
• Controls Scanhead Select interface (transducer select, personality retrieval, and connectivity
status)
• Transducer personality data identifies which transducer(s) are connected to the system
• Generates TGC1 and TGC2 waveforms
• Supplies TGC voltages to the Channel Boards for non-Matrix transducers or to the beam-
former resident in Matrix transducers
• Pulser regulators (±20-80 Vdc, ±60-120 Vdc) and LV CW regulator with disable support
• HV MUX current limited source voltages
• Regulates acquisition analog supply
• Pulser power monitor source
• High Speed Serial Interface to Scanhead Select
• TGC and HVMUX data demultiplexing and signal conversion
• Contains 320 MHz master oscillator and generates clock signals for all Acquisition hardware
(64 MHz, 40 MHz, 32 MHz and Link_Clk) distributed as differential PECL. Clock_Sync is dis-
tributed as LVCMOS
• A/D data acquisition block for measuring transducer mounted sensors, acquisition system
voltages, pulser supply voltage and current and system temperature transducers
• Power supply regulators and current limits for all voltages supplied to the transducer array
connectors (±12 Vdc, +5 Vdc, +REF, and ±HV MUX bias)
• Local regulation of ±15 V to ±12 V for transducer use
• Local generation of +10 V reference for TGC waveform D/As and transducer use
