DEVICE DESCRIPTION
The GENLINXGS9008 is a bipolar integrated circuit
designed to drive two 75 co-axial cables at data rates
exceeding 400 Mb/s. It directly interfaces with other
GENLINXdevices and can also be used as a general
purpose high speed cable driver.
While there are no plans to discontinue the GS9008, 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 0 mV to as high as 1100 mV 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 band gap reference voltage
VREF.
The GS9008 is packaged in an 8 pin SOIC, and operates
from a single +5 or -5 volt supply consuming typically only
170 mW of power.
