GENLINX II GS9028 Cable Driver
with Two Adjustable Outputs
DATA SHEET
FEATURES
DESCRIPTION
• SMPTE 259M compliant
The GS9028 is a second generation bipolar integrated
circuit designed to drive two 75Ω co-axial cables.
• two complementary outputs, adjustable from 50 to
1000mVp-p into 75Ω loads
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
adjusting the RSET resistor value.
• operational from DC to 622Mb/s
• nominal 470ps rise and fall times
• < ±7% output amplitude control
• 45% system power reduction over the GS9008
• no external pulldown resistors required
• input hysteresis
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.
• operational down to 80mV input amplitude
• operates from a single +5 or -5 volt supply
• 8 pin SOIC
• Pb-free and Green
The GS9028 is packaged in an 8 pin SOIC and operates
from a single +5 or -5 volt supply.
APPLICATIONS
4ƒsc, 4:2:2, and 4:4:4:4 serial digital video interfaces from
143Mb/s to 540Mb/s; general purpose high speed cable
driver applications.
