SCART to RF Converter Stable PLL Modulation

This SCART to RF converter transforms SCART digital or analog video/audio signals into stable RF output for legacy TV compatibility. Dimensions: not specified; weight: not specified; input: standard 21-pin SCART; output: coaxial RF (75Ω); RF output frequencies: switchable between 61.25 MHz and 67.25 MHz (custom frequencies 40–900 MHz available on request); RF system: PAL DK default, with optional I/BG/M/N/L/SECAM/NTSC support per regional requirement; RF output gain: 80 dB; power supply: 5 V / 500 mA via included USB cable; power consumption: < 0.5 W; modulation uses imported PLL phase-locked loop chip for frequency stability and zero drift. Includes 1× converter unit, 1× RF coaxial cable, and 1× USB power cable. The device enables long-distance signal transmission — extending effective range from 1–2 metres (typical SCART limit) to 100–1000+ metres via RF — while repurposing older TVs’ built-in tuners. It supports DVD players, set-top boxes, network media boxes, and game consoles with SCART outputs. Setup requires connecting SCART source → converter → RF OUT to TV’s RF IN (antenna/cable port), powering via USB, then performing auto/manual channel scan on the TV. For older TVs, manual sound system selection (e.g., DK) is required to avoid audio/video noise; newer smart TVs typically auto-detect.
