The evaluation board features one HV2903/AHA 12x12x1.2 mm 132-lead TFBGA
packaged integrated circuit, two MD1822K6-G 3x3x1 mm 16-lead QFN packaged inte-
grated circuits and four TC6320K6-G 4x4x1 mm 8-lead DFN packaged NMOS and
PMOS pair integrated circuits.
The board uses two high-speed 20 signal pair carrying capable right-angle backplane
connector, which is designed to work with Microchip HV MUX Controller Board
(ADM00825) as a control signal source.
The HV MUX Controller Board has an FPGA that generates pulser waveform and
logic control signals and a USB-bridge IC that connects the control board to a PC. By
means of a Microsoft Windows
® driver and GUI, the user can control the HV2903 and
two built-in pulsers.
Four switch terminals consisting two MUX configuration on the PCB have SMA
connectors to which user can connect loads. Jumpers close to SMA connectors are
for connecting the on-board dummy R-C load (330 pF//2.5 K
Ω ) optionally to the pulser
output.
WARNING
Risk warning of electrical shock . This board uses multiple hazardous high
voltages . Disconnect all high voltage supplies before working on it. Electrical
safety precautions must be taken when working on or using this board.
