Overview
The LMH0001SQE/NOPB is a SMPTE 259M / 344M Serial Digital Cable Driver produced by Texas Instruments. This component is specifically designed for use in SMPTE 259M / 344M serial digital video applications. It drives 75Ω transmission lines, such as Belden 8281 or Belden 1694A, at data rates up to 540 Mbps. The LMH0001 is powered by a single 3.3V supply and features adjustable output amplitude via a single external resistor. It operates within an industrial temperature range of −40°C to +85°C and is available in a 16-pin WQFN package.
