DESCRIPTION

The GS9028 is a second generation bipolar integrated

circuit designed to drive two 75

Ω co-axial cables.

The GS9028 features two complementary outputs whose

amplitude is controlled within ± 7%. The output signal levels

are also adjustable from as low as 50mV to as high as

1000mV with little change in other performance parameters.

The output amplitude of the output stage is varied by

The GS9028 consumes 45% less system power than the

GS9008 and does not require external pulldown resistors

resulting in a smaller PCB footprint. Operational with input

amplitudes as low as 80mV, the GS9028 is a robust serial

interface device.

The GS9028 is packaged in an 8 pin SOIC and operates

from a single +5 or -5 volt supply.
