GS9077 GS9077 HD-LINX III SD-SDI Cable Driver Features Description SMPTE 344M and SMPTE 259M compliant The GS9077 is a high-speed BiCMOS integrated circuit designed to drive one or two 75 co-axial cables. Dual coaxial cable driving outputs Selectable power down mode The GS9077 may drive data rates up to 540Mb/s and provides a disable pin that may be used to power down the 50 differential PECL input output stage. Pb-free/Halogen-free/RoHS & WEEE compliant The GS9077 accepts a LVPECL level differential input that Seamless interface to other HD-LINX III family may be AC coupled. External biasing resistors at the inputs products are not required. Single 3.3V power supply operation Power consumption is typically 168mW using a 3.3V power Operating temperature range: 0C to 70C supply. The GS9077 is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. Applications This component and all homogeneous subcomponents are SMPTE 344M and SMPTE 259M Coaxial Cable Serial RoHS compliant. Digital Interfaces.
