Product details
Overview
EL4543ILZ-T7S2714 from Renesas Electronics is a triple differential twisted-pair driver IC with integrated common-mode sync encoding for RGB video transmission. It delivers 350MHz bandwidth, 1200V/µs slew rate, and -75dB distortion at 5MHz, operating from single 5V–12V supply. It encodes HSYNC/VSYNC onto the common-mode voltage of three differential outputs, enabling full VGA+sync over three CAT5 twisted pairs.
For engineers reviewing the EL4543ILZ-T7S2714 datasheet, EL4543ILZ-T7S2714 pinout, EL4543ILZ-T7S2714 application, or EL4543ILZ-T7S2714 equivalent, this device supports high-fidelity analog video distribution in noise-sensitive environments, requires no external sync buffers, and enables cost-effective long-distance CAT5-based RGB transmission up to 200 ft without equalization.
Technical Context
The EL4543ILZ-T7S2714 integrates three fully differential amplifiers with fixed +2 gain and an internal logic encoder that maps HSYNC/VSYNC logic states to discrete common-mode DC levels (2.0V/2.5V/3.0V) across Red, Green, and Blue channels per Table 1. Its input common-mode range extends to the negative rail, supporting ground-referenced single-supply operation.
Each channel features matched gain and phase response, low 1.96–2.05 V/V DC gain tolerance, and balanced output drive (±60mA peak). The EN pin disables all amplifiers in 900ns, reducing supply current to 1.8mA (VS+) while preserving thermal stability via exposed pad thermal connection to VS−.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 350 MHz - supports full HD RGB video signal integrity up to ~1080p without significant attenuation |

Pinout & Package
The EL4543ILZ-T7S2714 is housed in a 20-lead 4×4 mm QFN package with exposed thermal pad connected internally to VS−. Pin compatibility matches the EL4543ILZ family; pin 1 (EN) is disable control, pins 2–3 and 8–9 and 11–12 are differential inputs (A/B/C), pins 14–15, 17–18, and 16–10 are differential outputs (A/B/C), pins 19 (VS−) and 15 (VS+) supply rails, and pins 5 (VSYNC), 6 (HSYNC) accept TTL/CMOS sync logic referenced to VS−.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Active-low enable | Drives all three amplifiers into high-impedance state when logic high; threshold scales linearly with supply voltage |
| VINA+/VINA− (Pins 2/3) | Differential input A | Accepts red video signal; fully differential architecture rejects common-mode noise on PCB traces |
| VINB+/VINB− (Pins 8/9) | Differential input B | Accepts green video signal; identical gain/phase matching to channel A for color fidelity |
| VINC+/VINC− (Pins 11/12) | Differential input C | Accepts blue video signal; supports same input common-mode range as other channels |
| VOUTA+/VOUTA− (Pins 17/18) | Differential output A | Drives red differential pair; outputs encoded common-mode sync level per Table 1 |
| VOUTB+/VOUTB− (Pins 14/15) | Differential output B | Drives green differential pair; maintains <0.01° differential phase error at 3.58 MHz NTSC frequencies |
| VOUTC+/VOUTC− (Pins 10/16) | Differential output C | Drives blue differential pair; common-mode DC level varies only with HSYNC/VSYNC state, not video content |
| VSYNC (Pin 5), HSYNC (Pin 6) | Logic sync inputs | TTL/CMOS-compatible; thresholds scale with VS+–VS− (e.g., 1.4 V at 5 V supply) |
| VS+ (Pin 15), VS− (Pin 19) | Power rails | Support 5–12 V single supply; exposed thermal pad must connect to VS− plane for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Triple differential amplifier architecture | Enables simultaneous RGB transmission over three independent twisted pairs without crosstalk-induced color skew |
| Integrated HSYNC/VSYNC common-mode encoding | Eliminates need for fourth twisted pair or separate sync buffer ICs, reducing BOM count and CAT5 wire usage |
| +2 fixed gain with matched channel response | Compensates for standard 75 Ω source and 100 Ω line termination, ensuring flat frequency response across channels |
| Single-supply operation down to 5 V | Permits direct integration into 5 V embedded systems without auxiliary voltage rails or level shifters |
| Low 36 mA typical total supply current | Reduces thermal load in space-constrained video distribution modules and multi-channel chassis designs |
| Disable function with sub-µs timing | Allows dynamic power cycling during blanking intervals or system sleep modes without latch-up risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple differential video driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EL4543IUZ | 24-lead QSOP package; identical electrical specs and sync encoding logic; higher θJA (88°C/W vs 40°C/W) | Preferred for prototyping or through-hole assembly; less suitable for thermally constrained high-density layouts | Select EL4543IUZ when board real estate permits larger footprint and manual soldering is preferred. |
| THS7374IPWPR | Quad-channel, 350 MHz video amplifier; no integrated sync encoding; requires external logic for HSYNC/VSYNC embedding | Used where sync is handled separately (e.g., FPGA-generated) or where fourth channel is needed for audio/data | Choose THS7374IPWPR only if sync encoding is implemented upstream and thermal budget allows higher dissipation. |
Compared with EL4543IUZ, the EL4543ILZ-T7S2714 offers superior thermal performance via its QFN thermal pad but requires reflow assembly; versus THS7374IPWPR, it delivers complete RGB+sync integration in one chip but lacks a fourth channel for auxiliary signals.

FAQ
What is the maximum recommended cable length for EL4543ILZ-T7S2714 without equalization?
The EL4543ILZ-T7S2714 supports reliable VGA+sync transmission up to 200 feet over CAT5 cable without external equalization. Beyond this distance, signal degradation due to high-frequency loss requires compensation-typically implemented using the EL9110 equalizer IC in conjunction with EL4543ILZ-T7S2714 in the SXGA Video Transmission System.
How does EL4543ILZ-T7S2714 encode HSYNC and VSYNC onto the common-mode voltage?
The EL4543ILZ-T7S2714 uses an internal logic encoder to map HSYNC/VSYNC logic states to three discrete common-mode DC levels (2.0 V, 2.5 V, 3.0 V) across its Red, Green, and Blue differential outputs per Table 1 in the datasheet. This encoding occurs independently per channel and does not modulate the differential video signal itself.
Can EL4543ILZ-T7S2714 operate from a ±5V split supply?
Yes, EL4543ILZ-T7S2714 supports ±5V operation, but sync inputs (HSYNC/VSYNC) and EN must be referenced to VS− (−5V), not ground. Level-shifting circuits (e.g., Figure 40 in FN7325) are required to translate ground-referenced TTL signals to the −5V reference domain before connecting to EL4543ILZ-T7S2714.
What is the role of the exposed thermal pad on the EL4543ILZ-T7S2714 QFN package?
The exposed thermal pad on the EL4543ILZ-T7S2714 is internally connected to VS− and must be soldered to a PCB copper pour tied to the VS− net. This connection reduces thermal resistance (θJA = 40°C/W) and prevents junction temperature exceedance under sustained 60 mA output loading-critical for continuous video transmission reliability.
Does EL4543ILZ-T7S2714 require external termination resistors on its outputs?
Yes, EL4543ILZ-T7S2714 requires 50 Ω series output termination per differential pair (e.g., 50 Ω resistors placed close to the output pins) to match 100 Ω twisted-pair characteristic impedance. Additionally, a >100 Ω common-mode termination (RCM) is recommended at the receiver end to extract sync without overloading the driver's common-mode output stage.
