GS6081 Gennum Products Features Description Supports data rates from 270Mb/s to 5.94Gb/s The GS6081 is a high-speed BiCMOS integrated circuit designed to drive one to four 75 coaxial cables. SMPTE ST 424, SMPTE ST 292 and SMPTE ST 259 compliant The GS6081 may drive data rates up to 5.94Gb/s and provides two selectable slew rates in order to achieve Supports DVB-ASI at 270Mb/s compliance to SMPTE ST 424, SMPTE ST 292 and Wide common-mode range input buffer SMPTE ST 259. 100mV sensitivity The GS6081 accepts industry-standard differential input supports DC-coupling to industry-standard levels including LVPECL and CML. differential logic Input trace equalization compensates for up to 10 inches of on-chip 100 differential data input termination FR4 trace loss while in HD, 3G and UHD modes. This feature is enabled and disabled using the EQ_EN pin. Input signal trace equalization The DISABLE1 and DISABLE2 pins power-down the first and Dual differential coaxial-cable-driving outputs second output drivers respectively, leaving the serial data selectable slew rates outputs in a high-impedance state. When applied adjustable output swing from 500mV to simultaneously, the entire device is powered-down. pp 1040mV pp The GS6081 features adjustable output swing using an external bias resistor. The single-ended output swing is independent disable controls for each output adjustable from 500mV to 1040mV . pp pp Robust signal presence function An output signal presence function, the SP pin, indicates Excellent output eye quality whether an active signal is present at the output of the Power supply operation at +3.3V or +2.5V GS6081. 135mW power consumption (+2.5V supply) The GS6081 can be powered from either a +3.3V or a +2.5V Operating temperature range: -40C to +85C supply. Power consumption is typically 135mW using a +2.5V power supply with one output enabled. Small footprint QFN package (4mm x 4mm) The GS6081 is Pb-free, and the encapsulation compound new dual-output pin out does not contain halogenated flame retardant. use the GS6080 for a single-output variant that is This component and all homogeneous subcomponents are drop-in compatible to the GS2988 RoHS compliant.
