3.Data transfer
4.24bit statistic structure
Note: Follow the order of RGB and the high bit sent first
Note: D0 and D1 are the data sent by the MCU. The customer can only send the D0 signal, and the D1 chip
will think that the signal is abnormal. This does not cause the signal to be delay transmitted.

※Application specification
1.12VDC application note:
Remark: 12V RV takes 2.7K resistor; 24V RV takes 6.8K resistor, RX resistor takes 39ohm. The signal
resistor should be a 70-100 ohm resistor to prevent the signal from being connected. The current-limiting
resistor is calculated as: R = (VDD - VLED-VDS) / 18mA, (VDD is supplied to the LED voltage; VLED is the
voltage of the LED, for example, three red The lamp voltage is 2X3 = 6, then the VLED is 6V; the VDS is
generally 1V.)
2. Cascaded signal driving capability and connection method:
◆ Due to the design of the signal regeneration circuit inside the chip, the cascading signal driving
capability is greatly enhanced. It is recommended to use twisted pair to increase the transmission
distance. To enhance the anti-jamming capability, add two 20P decoupling capacitors close to the IC
input. ◆Recommended for short-distance transmission, after the series resistors of D01 and D02 are
connected to the lower stage to prevent signal reflection; the working voltage is 4.5V-12V, the resistance
is 39 ohm, and the resistor should be installed close to the output of the IC. . ◆ It is recommended to
connect the ESD protection tube to the DI1 and DI2 ports at the working voltage of 24V to protect the
input port from high voltage damage.
