The AD8134 is a major advancement beyond using discrete
op amps for driving differential RGB signals over twisted pair
cable. The AD8134 is a triple, low cost differential or single-
ended input to differential output driver, and each amplifier has
a fixed gain of 2 to compensate for the attenuation of the line
termination resistors. The AD8134 is specifically designed for
RGB signals but can be used for any type of analog signals or
high speed data transmission. The AD8134 is capable of driving
either Category 5 (Cat-5) unshielded twisted pair (UTP) cable
or differential printed circuit board transmission lines with
minimal signal degradation.
A unique feature that allows the user to transmit balanced
horizontal and vertical video sync signals over the three
common-mode channels with minimal electromagnetic
interference (EMI) radiation is included on-chip.
The outputs of the AD8134 can be set to a low voltage state that
allows easy differential multiplexing of multiple drivers on the
same twisted pair cable, when used with external series diodes.

The AD8134 driver is a natural complement to the AD8143,
AD8129
, and
AD8130
differential receivers.
Manufactured on the Analog Devices next generation XFCB
bipolar process, the AD8134 has a large signal bandwidth of
225 MHz and a slew rate of 1600 V/μs. The AD8134 has an
internal common-mode feedback feature that provides output
gain and phase matching that is balanced to 60 dB at 50 MHz,
suppressing harmonics and reducing radiated EMI.
The AD8134 is available in a 24-lead LFCSP and can operate
over the 40°C to +85°C extended industrial temperature range.
