DESCRIPTION
The LMH0001 SMPTE 259M / 344M Serial Digital
Cable Driver is designed for use in SMPTE 259M /
344M serial digital video applications. The LMH0001
drives 75Ω transmission lines (Belden 8281, Belden
1694A or equivalent) at data rates up to 540 Mbps.
The output voltage swing of the LMH0001 is
adjustable via a single external resistor.
The LMH0001 is powered from a single 3.3V supply.
Power consumption is typically 125mW. The
LMH0001 is available in a 16-pin WQFN package.
