HD107S 2121 Pixel LED Diodes 2121 Digital LED chips with clock wire

1. Product Description
  HD107s 2121 is a two-wire transmission three-channel (RGB) drive control circuit and light-emitting circuit in one of the intelligent external control LED light source. Built-in constant current circuit and RC oscillator; internal integrated current gain control module, CMOS process, low voltage, low power consumption; when REXT is floating, the three-channel constant current driver default output of 17mA, the product is equipped with signal decoding module, Can also be REXT external resistor to adjust the required current, each output channel can output 8-bit (256 level) gray adjustable linear current; using two-wire output, DATA data and synchronous CLK signal, so that the series chip The output action synchronization; refresh rate up to 27KHz, showing more delicate and smooth, the default power does not light.

2. Feature
-The built-in light driver is integrated to form a complete external control pixel point.
-Integrated dual line serial cascaded constant current IC, clock and data dual line signal protocol.
-The default output constant current value for B/R/G light-emitting chips is 17mA.
-Supports a maximum clock signal input frequency of 32MHz and a maximum data signal transmission rate of 32Mbps.
The PWM scanning frequency is 27KHz.
-8-bit data per color, 256 levels of grayscale adjustable, good color consistency.
-Power on without self check mode, no signal input, no light on.
-SMD white bracket with a 120 ° light emission angle, high brightness and stability.
-Suitable for SMT and wave soldering processes.
-Compliant with RoHS and REACH environmental protection materials.
-Moisture proof grade: LEVEL4.
