September 13, 2007 Triple Differential Twisted-Pair Driver with Common-Mode Sync Encoding
The EL4543 is a high bandwidth triple differential amplifier
with integrated encoding of video sync signals. The inputs
are suitable for handling high speed video or other
communications signals in either single-ended or differential
form, and the common-mode input range extends all the way
to the negative rail enabling ground-referenced signalling in
single supply applications. The high bandwidth enables
differential signalling onto standard twisted-pair or coax with
very low harmonic distortion, while internal feedback
ensures balanced gain and phase at the outputs reducing
radiated EMI and harmonics. Features Embedded logic encodes standard video horizontal and
vertical sync signals onto the common mode of the twisted
pair(s), transmitting this additional information without the
requirement for additional buffers or transmission lines. The
EL4543 enables significant system cost savings when
compared with discrete line driver alternatives. Pb-free available (RoHS compliant) The EL4543 is available in both a 24 Ld QSOP package and
a 20 Ld QFN package and is specified for operation over the
-40В°C to +85В°C temperature range. VGA over twisted-pair H V COMMON
