The LMH0302 3-Gbps HD/SD SDI cable driver is designed for use in ST 424, ST 292, ST 344, and ST 259 serial digital video applications. The LMH0302 drives 75-Ω transmission lines (Belden 1694A, Belden 8281, or equivalent) at data rates up to
2.97 Gbps.

The LMH0302 provides two selectable slew rates for ST 259 and ST 424 or 292 compliance. The output driver may be powered down through the output driver enable pin.

The LMH0302 is powered from a single 3.3-V supply. Power consumption is typically 125 mW in SD mode and 165 mW in HD mode. The LMH0302 is available in a 16-pin WQFN package.
