Replaces the GS1528, GS1528A, or GS1578A

The LMH0002 provides two selectable slew rates for

SMPTE 259M and SMPTE 292M compliance. The

output voltage swing is adjustable via a single

external resistor.

The LMH0002 is powered from a single 3.3V supply.

Power consumption is typically 125 mW in SD mode

and 149 mW in HD mode. The LMH0002 is available

in an 8-pin SOIC or 16-pin WQFN package.
