Introduction

TX1812IXA5-F01 is an intelligent externally-controlled LED light source with integrated control and illumination circuits. Its physical dimensions are identical to a 2017 package LED, with each component functioning as an independent pixel. Each pixel integrates an intelligent digital interface with data latching, signal reshaping and amplification drive circuitry, power regulation circuit, built-in constant current circuit, and high-precision RC oscillator. The output driver employs patented pulse width modulation technology to ensure consistent color output across pixels. The data protocol uses a unipolar return-to-zero communication scheme. After power-on reset, each pixel receives data transmitted from the DIN port controller. The first 24 bits received are latched by the first pixel, with the remaining data forwarded downstream — each pixel extracting 24 bits as the signal propagates through the chain.

Features

• Integrated high-quality externally-controlled single-wire serial cascading constant-current driver IC
• Control circuit and die integrated in SMD 2017 package, forming a complete externally-controlled pixel with uniform and consistent luminous effect
• Built-in data reshaping circuit; signal received at any pixel is reshaped before output, preventing accumulation of waveform distortion along the line
• Built-in power-on reset and power-off reset circuits; LEDs default to OFF at power-up
• Integrated grayscale adjustment circuit (256-level grayscale)
• Red channel driver with special processing for more balanced color mixing
• Single-wire data transmission, supporting unlimited cascading
• Reshaping and forwarding enhancement technology; transmission distance between two nodes exceeds 10 meters
• Data transmission rate up to 800 Kbps; cascade count no less than 1024 pixels at 30 frames/second refresh rate
