DESCRIPTION
The GENLINX? GS9008A is a bipolar integrated circuit
designed to drive two 75 ? co-axial cables at data rates
exceeding 400Mb/s. 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.
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 600mV and 1000mV.
The gain of the output stages is varied by adjusting the V

voltage with respect to an internal band gap reference

.
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.
