36 Signal Connections
3.12 High Speed High Current Digital Output HSOUT
There are 4 channels of high speed high current digital outputs on
cPCI-8168. They are available on CN3 and CN4. Connections of
these outputs are shown in the following diagram. When the iso-
lated digital output goes to high, the sink current will come from
the external HSOUT supplied voltage. The time delay from
HSDOx to HSOUT is within 15ns. Maximum current output ability
is limited by the wire of cPCI-8168 to be 1 ampere. Each transistor
on IRF7303 is OFF when reset.
