DESCRIPTION
The GS1508 is a first generation very high speed bipolar integrated circuit designed to drive two 75Ω 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 RSET 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.
