APPLICATIONS
● LED decorative lighting.● Indoor/outdoor LED video or irregular screen. power supply.
● 256 Gray-scale adjustable and scan frequency is more than 2KHz.
● Built in signal reshaping circuit, to ensure waveform distortion do not accumulate after wave reshaping to the next driver
● Built-in electrify reset circuit and power-down reset circuit.
● Cascading port transmission signal by single line.
● Any two point the distance less than 5 Meters transmission signal without any increase circuit.
● When the refresh rate is 30fps, the cascade number is at least 1024 pixels.
● Send data at speed of 800Kbps. General description Also include a precision internal oscillator and a 12V voltage programmable constant current output drive. In the purpose of reduce power supply ripple, the 3 output channels designed to delay turn-on function. IC use single NZR communication mode. After the chip power-on reset, the DIN port receive data from controller, the first IC collect initial 24bit da...
