DEVICE DESCRIPTION
The GENLINX™ GS9009 is a bipolar integrated circuit
designed to drive four 75 Ω co-axial cables at data rates
exceeding 400 Mb/s. 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 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
bandgap reference voltage VREF.
Pinout is compatible with the GS9007 by interchanging
pins 3,4,5,6,9,10,11,12 on the GS9009 with pins 1,2,3,4,5,6,7,8
on the GS9007. In this way, a layout can be made for either
device depending on whether adjustability is desired or
not.
The GS9009 is packaged in a 14 pin SOIC, and operates
from a single +5 or -5 volt supply consuming typically only
250 mW of power.
