EL4543IU-T13

Overview

The EL4543IU-T13 is a triple differential twisted-pair driver manufactured by Renesas Electronics. It features a 350 MHz bandwidth and a 1200 V/µs slew rate, designed for high-speed video or communication signals. The device operates on a single supply voltage ranging from 5 V to 12 V, with a typical supply current of 36 mA. It provides fully differential inputs, outputs, and feedback to ensure balanced gain and phase. The component includes integrated common-mode sync encoding and supports ground-referenced signaling in single-supply applications.

Feature Summary

• Triple differential amplifier architecture with integrated common-mode sync encoding
• Fully differential inputs, outputs, and internal feedback loops
• High bandwidth capability for low harmonic distortion transmission
• Single supply operation compatible with ground-referenced signaling

Applications

• Twisted-pair drivers for analog signal transmission
• VGA over twisted-pair video distribution
• Differential line drivers in noisy environments

Procurement Notes

Verify the specific suffix 'T13' against official Renesas documentation to confirm reel packaging quantities and moisture sensitivity levels. Confirm end-of-life status and discontinuation notifications prior to design-in. Ensure compatibility with existing PCB footprints and thermal management requirements for the QSOP-24 package.

Selection Notes

Select this component when high-speed differential signaling over twisted pairs is required with minimal external components. The integrated sync encoding simplifies video signal processing. Consider the 350 MHz bandwidth and 1200 V/µs slew rate for fast transient response needs. Verify power supply constraints align with the 5 V to 12 V operating range.

Part Context

The EL4543 belongs to the EL4543 series of triple differential amplifiers. It is part of Renesas Electronics' portfolio of high-performance analog signal chain products. The device is designed to reduce radiated EMI through internal feedback mechanisms ensuring balanced output characteristics.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic differential amplifiers may not support the integrated common-mode sync encoding feature.
