Output Protection Functional Block
The vector data on the OUT-BUS of the Top PCA is connected to diode
packs (BAV99) that are connected to +5 volts and ground to clamp
overvoltage and undervoltage on the outputs. The output connectors (J1
and J2) have 33 ohm resistors in series with the output that provide
high speed serial termination as well as allowing current limiting in
cases of overvoltage, undervoltage, or stuck outputs.
