    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 amplifier 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 ...
