Power Supply and Ground Connector: Pin 2 VPOS, and Pins 1 and 3 Ground.
Input termination: Provide Termination for Input Sources.
VREF Output Load: This load is optional and is meant to allow
the user to simulate their circuit loading of the device.

Input AC-Coupling Capacitors
Video Filtering: C2 and C8 limit the video bandwidth of the Gain and Phase
output respectively.
Offset Feedback: These set the high-pass corner of the offset cancellation loop,
and thus with the input AC-coupling capacitors the minimum operating frequency. C4 = C6 = 1 nF (Size 0603)
GSET Signal Source: When SW1 is in the position shown, the device is in gain
measure mode, when switched it operates in comparator mode and a signal
must be applied to GSET.
PSET signal source: When SW2 is in the position shown, the device is in phase
measure mode, when switched it operates in comparator mode and a signal
must be applied to PSET.
