1 / 15 page  GS2978 HD-LINX® III Multi-Rate Dual Slew-Rate Cable Driver 1 of 15 GS2978 HD-LINX® III Multi-Rate Dual Slew-Rate Cable Driver Data Sheet 37186 - 7 March 2009 www.gennum.com Features • SMPTE 424M, 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® III family products • Single 3.3V power supply operation • Operating temperature range: 0°C to 70°C Applications • SMPTE 424M, SMPTE 292M, SMPTE 344M and SMPTE 259M Coaxial Cable Serial Digital Interfaces. Description The GS2978 is a high-speed BiCMOS integrated circuit designed to drive one or two 75Ω co-axial cables. The GS2978 may drive data rates up to 2.97Gb/s and provides two selectable slew rates in order to achieve compliance to SMPTE 424M, SMPTE 259M, SMPTE 344M and SMPTE 292M. The GS2978 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 GS2978 is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous subcomponents are RoHS compliant.
