APPLICATIONS
4ƒsc, 4:2:2 and 4:4:4:4 serial digital video co-axial
transmission interfaces from 143 to 540Mb/s; General
purpose cable driving applications (co-axial cable or UTP).
DESCRIPTION
DATA SHEET
The GS9029 is a second generation bipolar integrated
circuit designed to drive four 75co-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.
