SLBG-16 (Sync Generator) series synchronous signal generator is a high-precision product independently developed by Hunan Shuangln. It mainly provides standard synchronization signals to high-definition and standard systems as a locking source, ensuring that all devices in the TV system are synchronized. This prevents delays, jitter, and color distortion during A/D and D/A conversions due to system asynchrony. This product is suitable for devices that require standard synchronization signal locking, such as TV automatic broadcasting systems, logo machines, subtitle machines, and switchers. The product not only features 16-channel internal synchronous black screen and three-level synchronous signal output but also includes external synchronization input functionality and intelligent switching between internal and external synchronization signals. It can meet the synchronization requirements of various high-definition scenarios.
