XT1511-D20 Supplier: Paiming Core City
1. Product overview:
XT1511-D20 is a centralized control circuit? Photoelectric? Integrated intelligent external control LED light source. Its appearance is the same as that of an SMD 2020 LED lamp bead, and each element is a pixel. Does the pixel point contain? Intelligent digital interface data latch signal shaping amplification driving electricity? , power supply voltage stabilizing circuit, built-in constant current circuit, high-precision RC oscillator, output-driven PWM patented technology, effectively guarantee? The color consistency of light at pixel points is high.
Does the data protocol use unipolar return? Code communication mode, after the pixel is reset by power-on, the DIN terminal accepts the data sent by the controller. The first 24-bit data is extracted by the first pixel and sent to the data latch inside the pixel, and the rest of the data is internally shaped. Electricity? After shaping and amplification, it begins to forward the output to the next cascaded pixel through the DO port, and the signal is reduced by 24bit after each pixel is transmitted. Pixels adopt automatic shaping and forwarding technology, which makes the number of pixels cascade? Limited by signal transmission, only limited by signal transmission speed? Requirements.
LED low-voltage drive, environmental protection and energy saving. High, scattering angle? Big, consistent, ultra-low works? And long service life. Can you control electricity? Integrated on LED, electricity? Become? Simple, small size, installation? Jia Jian? .
2. Main application fields:

3. Feature description:
● Top SMD internally integrates high-quality external control single-wire cascade constant current IC;
● Power control? It is integrated with the chip in SMD 2020 components to form a complete external control pixel with uniform color temperature effect and high consistency.
● Built-in data shaping electricity? Any pixel receives the signal, and then outputs it after waveform shaping to ensure the line? Waveform distortion? what's up In addition
Low built-in power-on reset and power-off reset? , the power supply is not bright;
● Gray adjustment circuit (256 gray levels can be adjusted),
Red light drives special processing, and the color matching is more balanced.
● Single-wire data transmission with infinite cascade.
● Shaping and forwarding enhancement technology, the transmission distance between two points exceeds 10M.
● The data transmission frequency can reach 800Kbps. When is the refresh rate? What is the number of cascades at 30 frames per second? Less than 1024.
