GS2988

GS2988 Dual-Slew-Rate, Cable Driver with 3Gb/s Capability Features SMPTE 424M, SMPTE 292M and SMPTE 259M compliant Supports DVB-ASI at 270Mb/s Supports data rates from 270Mb/s to 2.97Gb/s Wide common-mode range input buffer Š 100mV sensitivity Š supports DC-coupling to industry-standard Description The GS2988 is a high-speed BiCMOS integrated circuit designed to drive one to two 75Ω coaxial cables. The GS2988 may drive data rates up to 2.97Gb/s and provides two selectable slew rates in order to achieve compliance to SMPTE 424M, SMPTE 292M and SMPTE 259M. The GS2988 accepts industry-standard differential input levels including LVPECL and CML. Input trace equalization compensates for up to 10 inches of FR4 trace loss while in HD and 3G modes. This feature can be disabled using the EQ_EN pin. The DISABLE pin powers-down the entire device. The GS2988 features adjustable output swing using an external bias resistor. The single-ended output swing is adjustable from 500mVpp to 1800mVpp. An output signal presence function, the OSP pin, indicates whether an active signal is present at the output of the GS2988. The GS2988 can be powered from either a 3.3V or a 2.5V supply. Power consumption is typically 110mW using a 2.5V power supply. The GS2988 is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous subcomponents are RoHS compliant. differential logic Š on-chip 100Ω differential data input termination ...
