WHAT IS THE HV2916 ANALOG SWITCH EVALUATION BOARD?
The HV2916 Analog Switch Evaluation Board can control the HV2916 device and
built-in pulsers that are connected to the two 2:1 MUX switches for demonstration using
the HV MUX Controller Board and GUI. Four switch outputs (SWT pins) from two 2:1
MUXes have SMA connectors which can be connected to four transducer elements.
The other side of the 2:1 MUX (SWS pins) is connected to the outputs of two built-in
MD1822 and TC6320 pulsers. The HV2916 Analog Switch Evaluation Board can drive
four transducer elements with 5 MHz, ±100V pulse signals.
The HV2916 Analog Switch Evaluation Board features one HV2916/AJA
10 x 10 x 1.1 mm 121-Ball TFBGA packaged integrated circuit, two MD1822K6-G
3 x 3 x 1 mm 16-Lead QFN packaged integrated circuits and four TC6320K6-G
4 x 4 x 1 mm 8-Lead DFN packaged NMOS and PMOS paired integrated circuits.
The HV2916 Analog Switch Evaluation Board uses two high-speed 20-signal pairs,
carrying capable right-angle backplane connectors, which are designed to work with
the HV MUX Controller Board 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 using
a Microsoft
®
Windows
®
-operated PC and the GUI software, the user can control the
HV2916 device and two built-in pulsers on the HV2916 Analog Switch Evaluation
Board.
Four switch terminals, consisting of two 2:1 MUX configurations on the PCB, have SMA
connectors to which the user can connect loads. The jumpers close to the SMA
connectors are for connecting the on-board dummy R-C load (330 pF//2.5 k
)
optionally to the switch outputs.
