LMH0302 - National Semiconductor

LMH0302 3Gbps HD/SD SDI Cable Driver

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.
