Description (Continued)
The GS3441 also features programmable output
de-emphasis with three, user-selectable operating levels to
support long PCB traces at the output of the device.
The device comes in a 24-pin, 4mm x 4mm QFN package
and is footprint compatible with Semtech’s GS2993
equalizer.
Power consumption of the GS3441 is typically 212mW
when DC-coupled at 1.2V.
