Description
Differential input pair from PCIE signal source. Signal is
passed through to the AOa+, AOa- pin respectively when
SEL=0. Signal is passed through to the AOb+, AOb- pin
respectively when SEL = 1.
Differential analog pass-through output. Signal from AI+
and AI- is passed through AOa+ and AOa- respectively
when SEL=0.
Differential analog pass-through output. Signal from AI+
and AI- is passed through AOa+ and AOa- respectively
when SEL=1.
Differential input pair from PCIE signal source. Signal is
passed through to the BOa+, BOa- pin respectively when
SEL=0. Signal is passed through to the BOb+, BOb- pin
respectively when SEL = 1.
Differential analog pass-through output. Signal from BI+
and BI- is passed through BOa+ and BOa- respectively
when SEL=0.
Differential analog pass-through output. Signal from BI+
and BI- is passed through BOb+ and BOb- respectively
when SEL=1.
Ground
No Connect - Reserved, do not connect
SEL controls the mux through a flow-through latch.
