www.DataSheet4U.com LMH0002 SMPTE 292M / 259M Serial Digital Cable Driver January 2006 LMH0002 SMPTE 292M / 259M Serial Digital Cable Driver General Description The LMH0002 SMPTE 292M / 259M serial digital cable driver is a monolithic, high-speed cable driver designed for use in SMPTE 292M / 259M serial digital video and ITU-T G.703 serial digital data transmission applications. The LMH0002 drives 75Ω transmission lines (Belden 8281, Belden 1694A or equivalent) at data rates up to 1.485 Gbps. 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 125mW in SD mode and 149mW in HD mode.
