EL4543 is a high bandwidth triple differential amplifier that integrates video synchronization signal coding. The input is suitable for processing high-speed video or other communication signals in single ended or differential form. The common-mode input range extends all the way to the negative rail, enabling ground reference signals in single power applications.
Pinouts
High bandwidth enables differential signals to be transmitted to standard twisted-pair or coaxial cable with very low harmonic distortion, while internal feedback ensures balanced gain and phase at the output, reducing radiated EMI and harmonics. Embedded logic encodes standard video horizontal and vertical synchronization signals onto the common mode of the twisted pair, transmitting this additional information without the need for additional buffers or transmission lines.
Block diagram
The EL4543 provides significant system cost savings compared to discrete line driver alternatives. The EL4543 is available in 24 Ld QSOP and 20 Ld QFN packages and is specified to operate in the temperature range -40°C to +85°C.
