GENERAL DESCRIPTION  
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.

Figure 2. Output Balance vs. Frequency  
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.  
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 AD8134 is available in a 24-lead LFCSP and can operate  
over the −40°C to +85°C extended industrial temperature range.  
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.
