GS2978 HD-LINX® III Multi-Rate Dual Slew-Rate Cable Driver Features - SMPTE 424M, SMPTE 292M, SMPTE 344M and SMPTE 259M pliant - Dual coaxial cable driving outputs with selectable slew rate - 50Ω differential PECL input - Pb-free and Ro HS pliant - 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 Bi CMOS 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 pliance 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 168m W using a 3.3V power supply. The GS2978 is Pb-free, and the encapsulation pound does not contain halogenated flame retardant. This ponent and all homogeneous subponents are Ro HS pliant.
