Driver takes sync encoding onboard
The Elantec EL4543 is the latest addition to Intersil's high-speed operational amplifier portfolio
The latest addition to Intersil's high-speed operational amplifier portfolio, the Elantec EL4543 contains embedded logic which 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.

Switching regulators protect against spikes
High-efficiency 2A integrated FET step-down DC/DC switching regulators support wide operating input voltages and can handle transient spikes up to 100V
The EL4543 is ideally suited to commercial and consumer applications that use Cat5 cable for transmitting high quality video, and it enables significant system cost savings when compared with discrete line driver alternatives.
With 350MHz -3dB bandwidth, the EL4543 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.
This new addition to the Elantec op-amp family is designed to provide significant cost savings for systems transmitting video signals over twisted pair cabling such as Cat5.
The EL4543 allows system designers to now transmit five signals (red, green, blue (RGB), Hsync and Vsync) using only three twisted pairs.
The Hsync and Vsync information can be recovered on the back end with the matching Elantec EL9110 differential receiver and equaliser.
