SK9822-A 5050 RGB Pixel LED Chip upgrade of SK9822

SK9822-A 5050 RGB Pixel LED Chip upgrade of SK9822

  SK9822-A is the upgrade type of SK9822, PWM refresh rate can be 27kHz, Oscillator Frequency is more than 30MHz.
SK9822-A RGB LED chip is same with SK9822 with a type ic for the three-color RGB Diming control strip and string ,This ic using the CMOS process to provide three-color RGB LED output driver to adjust the output with 256 gray scale and 32 brightness adjustment,SK9822-A RGB LED diodes with 2 signal output way, one is clock ,another is data, the clock and data is synchronizated ,so that the crystal cascade piece of output movement is sychronizated.
