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, with amplitudes 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.
