This pin is DC coupled
and matched to 50 Ohms.
This pin is DC coupled. For applications not requiring opera-
tion to DC, this port should be DC blocked externally using a
series capacitor whose value has been chosen to pass the
9
IF
necessary IF frequency range. For operation to DC, this pin
must not source or sink more than 2 mA of current or part
non-function and possible part failure will result.
