  High Resolution Video Solutions Using Single 5V Power
  Design Note 396
  Jon Munson
  Introduction
  Video cable driver amplifier output stages traditionally
  require a supply voltage of at least 6V in order to provide
  the required output swing. This requirement is usually
  met with 5V supplies by adding a boost regulator or a
  small local negative rail, say via the popular LTВ®1983-3.
  Such additional circuitry is unnecessary in typical 1VP-P
  video connections, such as HD component video, if the
  cable driver amplifiers simply offer near rail-to-rail output
  capability when powered from 5V.
  Standard definition and SVGA (800 × 600 pixel) low voltage
  devices have been available from Linear Technology for
  some time (see Design Note 327), but a number of recent
  device developments have made it possible to produce
  high resolution video devices that operate on a single 5V power supply. Some parts that п¬Ѓt this mold include the
  LT6556, a UXGA-resolution (1600 Г— 1200 pixel) RGB 2:1
  input-port buffered multiplexer (MUX); the LT6557 and
  LT6558 UXGA fixed gain triple amplifiers that include
  on-chip biasing to minimize external part count; and the
  LT6559 triple ampliп¬Ѓer that provides flexible, cost effective …

  DESIGN IDEAS L Triple Amps Handle High-Res
  Workstation Video from
  Single Supplies
  Introduction
  Cutting edge, high resolution workstation displays demand cutting edge
  bandwidth and slew rate specs of their
  video amplifiers. Displays supporting
  1920 Г— 1200 pixels, for example, must
  handle over 200Mpixels/s, less than
  п¬Ѓve nanoseconds per pixel! System
  supply voltages have also been dropping in order to accommodate the new,
  faster digital processor technologies.
  Historically the fast amplifiers used for
  these formats required a total power
  supply of at least 6V, particularly in
  cable driver applications. Enter the
  LT6557 and LT6558, ultra-fast triple
  video amplifiers with internally fixed
  gains of two and unity, respectively.
  These devices have been specifically
  engineered to operate on single supply voltages down to 3.3V and yet
  maintain high bandwidth. Now it is
  practical to use a low voltage digital …
