GS2989

The GS2989 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 GS2989 accepts industry-standard differential input levels including LVPECL and CML.

Input trace equalization compensates for up to 10 inches of FR4 trace loss. This feature can be disabled using the EQ_EN pin.  The DISABLE1 and DISABLE2 pins power-down the first and second output drivers respectively, leaving the serial data outputs in a high-impedance state. When applied simultaneously, the entire device is powered-down.

The GS2989 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 GS2989.

The GS2989 can be powered from either a 3.3V or a 2.5V supply. Power consumption is typically 125mW using a 2.5V power supply with one output enabled.

The GS2989 is Pb-free, and the encapsulation compound does not contain halogenated flame retardant.  This component and all homogeneous subcomponents are RoHS compliant.
