73M1966B Demo Board User Manual
4 Connecting the Demo Board Directly to a PCM Test Set
The 73M1966B Demo Motherboard conveniently provides a power connector, a power switch, PCM
interface connectors, and clock connectors. However, it is not necessary to utilize the Motherboard when
evaluating the device set. In some applications, it might be better to directly connect the 73M1966B
Demo Board to the PCM channel test set. Even without the Motherboard, the 73M1966B can be used
with the GUI and a channel test set.
If only the 73M1966B Demo Board is used, the two-row J1 connector has all the necessary signals to
connect to the digital signals of the channel test set and 3.3 V power as shown in Figure 2. Other PCM
highway test sets should also require only the 73M1966B Demo Board to perform similar tests.
