It directly interfaces with other GENLINX™ devices and can also be used as a general purpose high speed cable driver. While there are no plans to discontinue the GS9008A, Gennum has developed a successor product with improved features and performance called the GS9028. The GS9028 is recommended for new designs. GS9008A NOT RECOMMENDED FOR NEW DESIGNS The differential inputs are AC-coupled and internally DCrestored 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 600mV and 1000mV. The gain of the output stages is varied by adjusting the VSET voltage with respect to an internal band gap reference voltage VREF. The GS9008A is packaged in an 8 pin SOIC, and operates from a single +5 or -5 volt supply consuming typically only 170mW of power.

VOUT is measured across a correctly terminated load, back matched to the device. The peak to peak voltage of the device itself is 2 x VOUT. 2. VOUT is proportional to VSET and VSET may be an external low impedance, high stability supply. In this case the amplitude temperature coefficient will not be guaranteed. 2 of 4 GENNUM CORPORATION 29781 - 1 INPUT/OUTPUT CIRCUITS VCC VCC VCC 400 400 VCC GS9008A SERIAL INPUTS VREF1 0.5p 400 VREF1 + VREF2 VOUT VCC NOT RECOMMENDED FOR NEW DESIGNS Figure 1 Input Circuit (Pins 6 and 7) VOUT Figure 2 Output Circuit (Pins 1 and 2) +5V OUTPUT LEVEL ADJUST 10k 0.1 1.8p 5 INPUT SIGNAL INPUT SIGNAL 6 7 8 + 10 0.1 150 4 3 1.0 68 OUTPUT -1 (75Ω) GS9008A 2 1.0 1 1.8p 150 68 OUTPUT -1 (75Ω) All resistors in ohms, all capacitors in microfarads unless otherwise stated.
