It directly interfaces with other GENLINX™ devices and can also be used as a general purpose high speed cable driver. The differential inputs are AC-coupled and internally DC- restored which allows correct passage of pathological check codes associated with the serial digital standards. Even though the inputs are AC coupled, static protection diodes at each input restrict the DC differential so that if the driving source uses the opposite polarity power supply, external DC blocking capacitors must be used. Correctly terminated output signal levels are adjustable from as low as 0mV to as high as 1100mV with little change in other performance parameters. Performance is guaranteed for output levels between 600 mV and 1000 mV. The gain of the output stages is varied by adjusting the VSET voltage with respect to an internal bandgap reference voltage VREF. Pinout is compatible with the GS9007A by interchanging pins 3,4,5,6,9,10,11,12 on the GS9009A with pins 1,2,3,4,5,6,7,8 on the GS9007A. In this way, a layout can be made for either device depending on whether adjustability is desired or not. The GS9009A is packaged in a 14 pin SOIC, and operates from a single +5 or -5 volt supply consuming typically only 250mW of power.
