Fastest Digital Addressable RGB 5050LED Chip sk9822A ,-it is a update of apa102 led,apa107

The frequency of PWM, Oscillator Frequency is 30MHz (  tranmission rate:30M HZ)

which is Absolutely a best perfect pixel led to  replace  APA102/APA102C/APA107led,

bec it is much more stable and faster and energy saving  and much compettive in cost price 

Product Description
sk9822A RGB LED chip is same with APA102  with one IC for the three-colors RGB diming control strip and string,

this ic use the CMOS process to provide three-colors RGB LED output driver to adjust the output with 256 grey scale and 32 brightness adjustment,

sk9822A RGB LED diodes with 2 signal output way, one is clock , another is data, the clock and data are synchronized, so that the crystal cascade piece of output movement is synchronized.

Advanatages of  sk9822A LED

1, CLK+Data double wire transfer
2, PWM refresh rate can be +27kHz
3, Max transfer speed is 30MHz.
4, And sk9822A  with built-in sleep function, no work no electric consumption, very good for battery-powered application,
5,sk9822A  Led lights up more brightness ,large lighting beam,
6,  8bits ; grade gray scales 65536 ( 16 bits)optional
7,sk9822A  LEDs, the upgrade of apa102/apa107 LED,
8,You can see the difference of sk9822A  and APA102 LED Strip, they are both 5m length.When light up white color,
APA102 led strip has color mixed, not pure white color, so voltage drop is obvious….
sk9822A  LED strip is better, white color, no voltage drop within 5m length
CMOS process, low voltage, low consumption
Synchronization of two-way
Choose positive output or negative RGB three-color LED output
8 bit(256 level) color set, 5bit(32 level) brightness adjustment
Build-20ma constant current output
With self-detection signal build in support for continuous oscillation PWM
output, can be maintained static screen

What is the difference between sk9822A ,apa107,apa102 and SK9822 led strips
APA102: 20+ kHz PWM, transmission rate 20MHZ:20k PWM refresh rate;
APA107: 9 kHz PWM, transmission rate 30MHZ;  27K  PWM refresh rate;
sk9822A: 27+ kHz PWM (the upgrade of APA107), transmission rate 30MHZ
In conclusion, sk9822A  is one real product that can replace APA102/apa102C/apa107
