DESCRIPTION
The GENLINX? GS9009A is a bipolar integrated circuit
designed to drive four 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.
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 V
SET
voltage with respect to an internal bandgap reference
voltage V
REF
.
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.
