The GS9029 is a second generation bipolar integrated circuit designed to drive four 75ohm co-axial cables.
The GS9029 features two pairs of complementary outputs whose amplitude is controlled within ±7.5%. The output signal levels are also adjustable from 50mVp-p up to 1000mVp-p with little change in other performance parameters. The amplitude of the output stage is varied by adjusting the RSET resistor value. The patented current mode outputs ensure superior output return loss and minimal over shoot. The rise/fall time circuitry allows wide range operation and provides symmetrical balanced outputs to reject power supply noise. In addition high output isolation ensures that the cable driver outputs are not affected by the performance or status of other outputs. Operational with input amplitudes as low as 80mV, the GS9029 provides a robust serial interface.
The GS9029 is packaged in a 16 pin narrow SOIC and operates from a single +5 or -5 volt supply. Typical system power consumption is 320mW which is 40% less than the GS9007.
