4、 System Design Guidelines
4.1. Cascade configuration and data protocol
CXLE87192 adopts an efficient cascaded data transmission mechanism, where each chip receives 24 bits of data (8 bits each for R, G, and B) and automatically forwards subsequent data. When the system is working, the controller first sends the display data of all cascaded chips, and finally sends a Reset signal (low level valid, duration>200&ms), and all chips synchronously update the display output.
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 should be done at the signal input
Connect the output pins 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 VDD of the chip
The GND pin should be as short as possible to achieve the best decoupling effect and stabilize the chip operation.
4.2. Data transmission format, Dn's data format：
• Each pixel occupies 24 bits: R [7:0], G [7:0], B [7:0]
• Per bit cycle: 1.25μ s (800Kbps)
• Reset signal: Low level>200&ms triggers display update
Each display packet contains 8× 3 bits of data, high bits are sent first.
R [7:0]: Used to set the PWM duty cycle of the OUTR 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 OUTG 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 OUTB output. All 0 codes indicate shutdown, all 1 code indicates maximum duty cycle, adjustable in 256 levels.
4.3. Power configuration calculation
According to different input voltages, it is necessary to configure appropriate power resistors:
Common configuration reference:
• 5V power supply: no external resistor required
• 12V power supply: series connection of 650Ω resistance
• 24V power supply: series connection of 1.8kΩ resistance
CXLE87192 can be configured for DC6-24V voltage supply, but different power resistors and resistance meters should be configured according to different input voltages
Calculation method: The VDD port current is calculated at 10mA, and the VDD series resistance R=(DC-5.5V)÷ 10mA (DC is the power supply voltage).
The list of typical values for configuring resistors is as follows:
4.4. Constant current optimization design
To ensure that the chip operates in the optimal constant current state, it is recommended to maintain the OUT port voltage between 1.2V and 3V. Voltage can be adjusted by connecting resistors in series:
among which
• VDC: System Drive Voltage
• VLED: Single LED conduction voltage drop
• n: Number of LEDs in series
• IOUT: Constant current value (14mA)
CXLE87192 is a constant current drive. According to the constant current curve, when the OUT port voltage reaches 0.8V, it will enter a constant current state. But it's not electricity
The higher the voltage, the better. The higher the voltage, the greater the power consumption of the chip, and the more severe the heating, which reduces the reliability of the entire system. Suggest opening the OUT port
A suitable voltage range of 1.2-3V during operation can be achieved by connecting resistors in series to reduce the excessive voltage at the OUT port. The following are the selections
The calculation method for resistance value:
System driving voltage: DC
Single LED conduction voltage drop: Vled
Number of LEDs in series: n
Constant current value: Iout
Constant current voltage: 1.5V
Resistance: R
R=（DC-1.5V -Vled×n）÷ Iout
Example: System power supply: DC24V, voltage drop for a single LED conduction: 2V, number of LEDs in series: 6, constant current value: 14mA, according to the above specifications
The formula yields: R=(24V-1.5V-2V× 6)÷ 14 mA≈ 750Ω Just connect 750&Omega in series on the OUT port; The resistors on both sides are sufficient. this
Externally, if it is necessary to consider long-distance cascading of light strips, there will be a voltage drop at the farthest end of the power supply. The constant current voltage of 1.5V can be increased to 3V, at which point R=(24V-
3V-2V× 6）÷ 14 mA=643Ω。
4.4. Drive capability expansion
CXLE87192 supports output parallel current expansion, with a constant output of 14mA per OUT port:
• Parallel connection of two OUT ports: 28mA
• Three OUT ports in parallel: 42mA
When used in parallel, software cooperation is required to write three sets of register values separately to achieve precise current control and color mixing effect.
CXLE87192 outputs a constant 14mA current at each OUT port. If the user needs to increase the driving current, the RGB three OUT ports can be short circuited
After use, for every OUT port short circuited, the maximum constant current value will increase by 14mA. After short circuiting all three OUT ports, the maximum constant current value can reach 42
MA. This method requires software to simultaneously control and write three sets of register values to achieve precise current control and larger driving power
Flow.
4.5. Functional Description
After the chip is powered on and reset, it begins to receive display data. After receiving 24 bits, the DO port begins to forward messages from the DIN or FDIN end
Data provides display data for the next cascaded chip. Before forwarding data, the DO port remains at a low level. If DIN or FDIN input
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 reset
Waiting to receive new data, after receiving the initial 24 bit data, forwarding the data through the DO port, the chip did not receive the Reset signal
Before the number, the original outputs of OUTR, OUTG, and OUTB remain 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
It is consistent.
4.5.1 A complete frame of data structure
D1、D2、D3、D4、… … 、 The format of Dn data is the same, where D1 represents the display data packet of the first chip in the cascade, and Dn represents the display data packet of the first chip in the cascade
Display data packets for n chips, each containing 24 bits of data. Reset indicates a reset signal, low level is valid.
4.5.2 Data reception and forwarding
Among them, S1 is the data sent by the Di port of the controller, and S2, S3, and S4 are the data forwarded by the cascaded CXLE87192.
Controller Di Port Data Structure: D1D2D3D4… … Dn；
Controller Fi Port Data Structure: DxD1D2D3D4… … Dn; where Dx is any 24 bit data bit.
The data reception and forwarding process during chip cascading is as follows: the controller sends data packet D1, chip 1 receives the first set of 24 bits, and at this time, the chip
Film 1 has not been forwarded; Then the controller sends data packet D2, and chip 1 receives the second set of 24 bits, as chip 1 already has the first set stored
24bit， Therefore, chip 1 forwards the second set of 24 bits to chip 2 through DO, and chip 2 receives the data packet D2 forwarded by chip 1
Chip 2 has no forwarding; Then the controller sends data packet D3, and chip 1 forwards the received third set of 24 bits to chip 2
Chip 2 already has a second set of 24 bits, so chip 2 forwards the third set of 24 bits to chip 3, which receives the third set
24bit； Similarly, all cascaded chips will receive their respective display data. If the controller sends a Reset signal at this time
Some chips will reset and decode the 24 bit data they receive to control the OUT port output, completing a data refresh cycle
Return to the receiving preparation state. Reset low level is effective. If the low level is maintained for more than 200 seconds, the chip will be reset;
5、 Detailed explanation of performance characteristics
5.1. Efficient cascading capability
CXLE87192 adopts automatic shaping and forwarding technology, and the signal will not be distorted or attenuated during cascade transmission. This feature is particularly important for large LED systems. Based on the number of cascaded pixels, the system refresh rate can be calculated as follows:
| Pixel count | refresh time | Maximum refresh rate |
|---|---|---|
| 1-400 | 12ms | 83Hz |
| 1-800 | 24ms | 41Hz |
| 1-1000 | 30ms | 33Hz |
5.2. Accurate constant current characteristics
CXLE87192 enters a constant current state when the OUT port voltage reaches 0.8V, with minimal current difference between channels. When the load voltage changes, the output current remains highly stable, ensuring consistent LED brightness and color accuracy.
When applying CXLE87192 to LED product design, the current difference between channels and even chips is extremely small. When the load terminal voltage changes
At this time, the stability of its output current is not affected, and the constant current curve is shown in the following figure:
5.3. Flexible system configuration
Supports dual data input channels (DIN and FDIN), which can switch between each other in normal mode. This feature improves the reliability of the system, even if one input channel fails, the system can still function normally through the backup channel.
5.4. How to calculate data refresh rate
The data refresh time is calculated based on how many pixels are cascaded in a system, and a set of RGB is usually one pixel (or one pixel)
A CXLE87192 chip can control a set of RGB.
Calculate according to normal mode:
The 1-bit data period is 1.25 μ s (frequency 800KHz), and one pixel data includes R (8-bit), G (8-bit), and B (8-bit)
24 bits in total, with a transmission time of 1.25μ s× 24=30μs。 If there are 1000 pixels in a system, refresh all at once to display them
The time is 30μ s× 1000=30ms (ignoring Reset signal time), which means a one second refresh rate of 1÷ 30ms≈ 33Hz。
The following is a table of the highest data refresh rate corresponding to cascading points:
6、 PCB design suggestions
