Description

AI+

AI-

Differential input

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.

AOa+

AOa-

Differential pass-through

input

Differential analog pass-through output. Signal from AI+

and AI- is passed through AOa+ and AOa- respectively

when SEL=0.

AOb+

AOb-

Differential pass-through

input

Differential analog pass-through output. Signal from AI+

and AI- is passed through AOa+ and AOa- respectively

when SEL=1.

BI+

BI-

Differential input

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.

BOa+

BOa-

Differential pass-through

input

Differential analog pass-through output. Signal from BI+

and BI- is passed through BOa+ and BOa- respectively

when SEL=0.

BOb+

BOb-

Differential pass-through

input

Differential analog pass-through output. Signal from BI+

and BI- is passed through BOb+ and BOb- respectively

when SEL=1.
