The differential output can be DC-coupled to Semtech’s

reclockers and cable drivers, as well as industry-standard

+1.2V, +1.8V and +2.5V CML logic by changing the voltage

applied to the VCC_O pin.

The GS3140 also features programmable output

de-emphasis with eight user-selectable operating levels to

support long PCB traces at the output of the device. The

output swing can be programmed, via the user interface,

The device comes in a 16-pin, 4mm x 4mm QFN–COL

package.

Power consumption of the GS3140 is typically 84mW when

DC-coupled to a +1.2V termination voltage with

The GS3140 is Pb-free, and the encapsulation compound

does not contain halogenated flame retardant.

This component and all homogeneous subcomponents are

RoHS compliant.
