Triple Differential Twisted-Pair Driver with  
Common-Mode Sync Encoding  
Features  
• Fully differential inputs, outputs, and feedback  
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.  
• 350MHz -3dB bandwidth  
• 1200V/µs slew rate  
• -75dB distortion at 5MHz  
• Single 5V to 12V operation  
• 50mA minimum output current  
• Low power - 36mA total typical supply current  
• Pb-free plus anneal available (RoHS compliant)  
Applications  
• Twisted-pair drivers  
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.  
• Differential line drivers  
• VGA over twisted-pair  
• Transmission of analog signals in a noisy environment  
The EL4543 is available in a 24 Ld QSOP package and is  
specified for operation over the -40°C to +85°C temperature  
range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free  
material sets; molding compounds/die attach materials and 100% matte tin  
plate termination finish, which are RoHS compliant and compatible with  
both SnPb and Pb-free soldering operations. Intersil Pb-free products are  
MSL classified at Pb-free peak reflow temperatures that meet or exceed  
the Pb-free requirements of IPC/JEDEC J STD-020.
