LN-S114 1x4 SDI Distribution Amplifier DA 3G-SDI 300m SMPTE Wide Voltage

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.

Core Technical Architecture

In-Depth Technical Analysis

1. Signal Conditioning
   Built-in cable equalization compensates for signal loss over long cables. Clock recovery restores signal timing for jitter-free performance.

2. 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.

3. 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.

4. Physical & Environmental
   Compact metal housing with ESD protection. Designed for continuous operation in broadcast and professional AV environments.
