www.DataSheet4U.com GS1578A HD-LINX® II Multi-Rate Dual Slew-Rate Cable Driver GS1578A Data Sheet Features SMPTE 292M, SMPTE 344M and SMPTE 259M compliant Dual coaxial cable driving outputs with selectable slew rate 50Ω differential PECL input Pb-free and RoHS compliant Seamless interface to other HD-LINX® II family products Single 3.3V power supply operation Operating temperature range: 0°C to 70°C Description The GS1578A is a second generation high-speed BiCMOS integrated circuit designed to drive one or two 75Ω co-axial cables. The GS1578A may drive data rates up to 1.485Gb/s and provides two selectable slew rates in order to achieve compliance to SMPTE 259M, SMPTE 344M and SMPTE 292M. The GS1578A accepts a LVPECL level differential input that may be AC coupled. External biasing resistors at the inputs are not required. Power consumption is typically 168mW using a 3.3V power supply. The GS1578A is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous subcomponents are RoHS compliant. Applications SMPTE 292M, SMPTE 344M and SMPTE 259M Coaxial Cable Serial Digital Interfaces.
