3 Description

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.
