3.6. Function Description;
3.6.1 Display data; After the chip is powered on and reset, it begins to receive display data. After receiving 24 bits, the DO port starts forwarding data that continues to be sent from the DIN or FDIN end,
Provide display data for the next cascaded chip. Before forwarding data, the DO port remains at a low level. If the DIN or FDIN input resets
Reset signal, the OUT port of the chip will output a PWM waveform with corresponding duty cycle based on the received 24 bit display data, and the chip will wait for connection again
Receive new data, and after receiving the initial 24 bit data, forward the data through the DO port. Before the chip receives the Reset signal, R、
G. The original output of B remains unchanged.
The chip adopts automatic shaping and forwarding technology, and the signal will not be distorted or attenuated. For all cascaded chips, the data transmission cycle is
coincident. 3.6.2. One complete frame of data structure;

R [7:0]: Used to set the PWM duty cycle of R output. All 0 codes indicate shutdown, all 1 code indicates maximum duty cycle, adjustable in 256 levels. G [7:0]: Used to set the PWM duty cycle of G output. All 0 codes indicate shutdown, all 1 code indicates maximum duty cycle, adjustable in 256 levels. B [7:0]: Used to set the PWM duty cycle of B output. All 0 codes indicate shutdown, all 1 code indicates maximum duty cycle, adjustable in 256 levels. 3.6.3. Data reception and forwarding
Among them, S1 is the data sent by the Di port of the controller, and S2, S3, S4, and Sn are the data forwarded by the cascaded CXLE87195.
Controller Di and Fi2 port data structure: D1D2D3D4… … Dn；
Controller Fi Port Data Structure: DxD1D2D3… … Dn；
Among them, Dx is any 24 bit data bit.
The process of chip cascading and data transmission and forwarding is as follows: the controller sends data S1, chip 1 absorbs D1, and if there is no reset at this time
Signal, chip 1 will continue to forward the data sent by the controller; Chip 2 absorbs D2. If there is no Reset signal at this time, chip 2
We will continue to forward the data sent by chip 1. Repeat this process until the controller sends a Reset signal, completing a data refresh cycle,
The chip has returned to the receiving preparation state. Reset low level is effective. If the low level is maintained for more than 80 seconds, the chip will be reset. 3.7. Constant current curve When applying CXLE87195 to LED product design, the current difference between channels and even chips is extremely small, and when the load terminal voltage occurs
When changing, the stability of its output current is not affected, and the constant current curve is shown in the following figure:
4、 Typical Application Design
4.1. Dual line cascaded architecture
The controller sends data through DIN or FDIN, and the chip receives and forwards it in sequence, forming a cascaded link. After receiving 24 bits of display data, each chip automatically forwards the subsequent data to the next level to achieve overall control.
To prevent the instantaneous high voltage generated by live plugging and unplugging of the product during testing from causing damage to the input and output pins of the chip signal, it is necessary to address the issues of signal input and output;
Output pin connected in series with 100Ω Protect the resistor. In addition, the 104 decoupling capacitors of each chip in the figure are indispensable, and they are routed to the VDD and GND of the chip;
Feet should be as short as possible to achieve the best decoupling effect and stabilize chip operation.
4.2. Protection circuit design
• Connect 100Ω in series with DIN, FDIN, DO ports; Resistors prevent high-voltage damage to chips during insertion and removal.
• A 0.1 μ F decoupling capacitor should be connected between VDD and GND of each chip, and placed as close as possible to the chip pins to enhance system stability.
4.3. Input/output equivalent circuit;
5、 Data refresh rate calculation
For example, with a data rate of 800KHz, the transmission time for each pixel (24 bits) is about 30 seconds. If the system cascades 1000 chips, the refresh time of the entire system is 30ms, and the refresh rate can reach 33.3Hz, which meets most dynamic display requirements. The following table shows the refresh rate reference for different cascading points:
| Pixel count | Fastest refresh time (ms) | Maximum refresh rate (Hz) |
|---|---|---|
| 1~500 | fifteen | sixty-six point seven |
| 1~1000 | thirty | thirty-three point three |
| 1~2000 | sixty | sixteen point seven |
The data refresh time is calculated based on how many pixels are cascaded in a system, with a set of RGB typically consisting of one pixel (or segment),
A CXLE87195 chip can control a set of RGB.
Calculated according to normal mode:;
The 1-bit data period is 1.25us (frequency 800KHz), and one pixel data includes R (8-bit), G (8-bit), and B (8-bit)
24bit， The transmission time is 1.25 US× 24≈ 30μs。 If there are a total of 1000 pixels in a system, the time it takes to refresh all displays at once
For 30μ s× 1000=30ms， The one second refresh rate is: 1÷ 30ms=33.3Hz。
The following is a table of the highest data refresh rate corresponding to cascading points:
| Normal Mode | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Pixel count | Fastest data refresh time (ms) | Maximum data refresh rate (Hz) | |||||||||||||||||||||||||||||||||||||||||||||||||||||
| 1~500 | fifteen | sixty-six point seven | |||||||||||||||||||||||||||||||||||||||||||||||||||||
| 1~1000 | thirty | thirty-three point three | |||||||||||||||||||||||||||||||||||||||||||||||||||||
| 1~2000 | sixty | sixteen point seven | |||||||||||||||||||||||||||||||||||||||||||||||||||||
