Introduction

TX1813AXA-F02 is an intelligent externally-controlled LED light source device integrating control circuitry and illumination circuitry. It shares the same form factor as a 5050 LED, with each component forming an independent pixel. Each pixel integrates a smart digital interface with data latch, signal reshaping and amplification drive circuit, power regulation circuit, built-in constant current circuit, and high-precision RC oscillator. The output drive utilizes patented PWM technology to effectively ensure color consistency within each pixel. The data protocol employs unipolar return-to-zero (RZ) communication. Upon power-on reset, the pixel receives data from the controller via the DIN port. The first 24 bits of data received are extracted by the first pixel, and the remaining data is reshaped and forwarded to subsequent pixels, with each pixel reducing the transmitted signal by 24 bits.

Features

• Default output constant current: 12mA, reducing power consumption of built-in LED dies.
• Integrated 256-level grayscale adjustment circuit.
• Built-in high-precision, high-stability oscillator.
• Data reshaping function: automatically reshapes and forwards subsequent data after receiving the current unit's data.
• Data transmission frequency up to 800Kbps.

Applications

• LED full-color illuminated channel letter light strings
• LED full-color modules
• LED magic color flexible and rigid light strips
• LED guardrail tubes
• LED landscape and scene lighting
