GS1528B HD-LINX II Multi-Rate Dual Slew-Rate Cable Driver Features Description SMPTE 292M, SMPTE 344M and SMPTE 259M The GS1528B is a second generation high-speed BiCMOS compliant integrated circuit designed to drive one or two 75 co-axial cables. Dual coaxial cable driving outputs with selectable slew rate The GS1528B may drive data rates up to 1.485Gb/s and 50 differential PECL input provides two selectable slew rates in order to achieve compliance to SMPTE 259M, SMPTE 344M and SMPTE Pb-free and RoHS compliant 292M. Seamless interface to other HD-LINX II family products The GS1528B accepts a LVPECL level differential input that Single 3.3V power supply operation may be AC coupled. External biasing resistors at the inputs Operating temperature range: 0C to 70C are not required. Applications Power consumption is typically 168mW using a 3.3V power supply. SMPTE 292M, SMPTE 344M and SMPTE 259M Coaxial Cable Serial Digital Interfaces The GS1528B is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous subcomponents are RoHS compliant.
