DESCRIPTION
The GS1508 is a first generation very high speed bipolar
integrated circuit designed to drive two 75? co-axial
cables. The GS1508 is a SMPTE 292M compliant cable
driver that directly interfaces with other Gennum HDTV
devices and can also be used as a general purpose high
speed cable driver.
The GS1508 features two complementary outputs whose
amplitude is controlled within a precise ±7% variation. The
output amplitude can be varied by adjusting the R
SET
resistor value.
The serial inputs can be AC coupled. The GS1508 is a low
power device that does not require external pull down
resistors. The GS1508 is packaged in an 8 pin SOIC and
operates from a single 5V power supply.
