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 75鈩?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 driv-
er 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 pack-
age.
