DESCRIPTION
The GS9028 is a second generation bipolar integrated circuit designed to drive two 75Ω 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 adjusting the RSET resistor value.
FEATURES
• SMPTE 259M compliant
• two complementary outputs, adjustable from 50 to 1000mVp-p into 75Ω loads
• 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
• operational down to 80mV input amplitude
• operates from a single +5 or -5 volt supply
• 8 pin SOIC
• Pb-free and Green
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.
