LMH0302

LMH0302 3Gbps HD/SD SDI Cable Driver PRELIMINARY April 2007 LMH0302 3Gbps HD/SD SDI Cable Driver General Description The LMH0302 3Gbps HD/SD SDI Cable Driver is designed for use in SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M serial digital video applications. The LMH0302 drives 75Ω transmission lines (Belden 1694A, Belden 8281, or equivalent) at data rates up to 2.97 Gbps. The LMH0302 provides two selectable slew rates for SMPTE 259M and SMPTE 424M / 292M compliance. The output driver may be powered down via the output diver enable pin. The LMH0302 is powered from a single 3.3V supply. Power consumption is typically 129 mW in SD mode and 162 mW in HD mode. The LMH0302 is available in a 16-pin LLP package.
