LN-S114 1x4 SDI Distribution Amplifier – Technical Overview
Professional-Grade Signal Distribution with Automatic Equalization and Reclocking
The LN-S114 is a broadcast-quality 1x4 SDI distribution amplifier engineered for signal integrity and reliability. It accepts a single 3G-SDI, HD-SDI, or SD-SDI input and outputs four independently buffered signals with full reclocking and cable equalization. Capable of handling bitrates up to 2.97Gbps, the unit supports SMPTE 424M, 292M, and 259M standards, making it suitable for high-end video production, OB trucks, and mission-critical AV systems. The wide voltage input (5–12V DC) and low power consumption ensure compatibility with mobile and fixed installations.

| Output Stage | 4× BNC with re-driven outputs | Ensures signal integrity across all outputs |
| Signal Processing | 2.97Gbps with clock recovery | Eliminates jitter and timing errors |
| Power Design | Wide voltage DC 5–12V input | Flexible power sourcing for field use |
| Housing | Metal enclosure with ESD protection | Reliable operation in demanding environments |
In-Depth Technical Analysis
Signal Conditioning
Built-in cable equalization compensates for signal loss over long cables. Clock recovery restores signal timing for jitter-free performance.
Output Performance
Each output is independently driven and isolated to prevent load-induced degradation. Supports simultaneous output of 3G-SDI, HD-SDI, or SD-SDI.
Compliance & Compatibility
Fully compliant with SMPTE 424M (3G-SDI), SMPTE 292M (HD-SDI), and SMPTE 259M (SD-SDI). Auto-detects input signal format and adjusts accordingly.
Physical & Environmental
Compact metal housing with ESD protection. Designed for continuous operation in broadcast and professional AV environments.
