GS1528B HD-LINX® II Multi-Rate Dual Slew-Rate Cable Driver 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 GS1528B is a second generation high-speed BiCMOS integrated circuit designed to drive one or two 75Ω co-axial cables. The GS1528B 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 GS1528B 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 GS1528B is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous subcomponents are RoHS compliant.
