Demonstration kit composition

There are essentially 3 methods to drive the STHV748 demo board, for each of them the

user must connect a custom PCB adapter, via the C1 connector, to drive the IC pulser.

6.1

Method 1 (flexible - based on BNC PCB adapter)

In this case, the demo board, described in Section 3, is being connected up, via the C1

connector, to a custom PCB adapter with 8 BNC connectors. A couple of BNC are dedicated

to IN1 and IN2 for each channel and usable for the external waveforms generator. In

addition, 2 switches are dedicated to connecting IN3 and IN4 to 0V or VDD, in accordance

with the truth table (see Table 2 and Figure 8). The composition of the demonstration kit is

shown in Figure 7 and 9.
