How to enhance the communication quality of interface chips, Unikeyic shares application tips
Whether it is an audio interface chip or a communication interface chip, in order to ensure the quality of signals and communication, besides choosing high-quality chips, it is also important to understand some techniques to improve the communication quality of chips in practical applications. unikeyicprovides a wealth of chip resources as well as techniques for enhancing chip communication quality that have been summarized through practical experience. Next, I will share them one by one.
Integrating Fault Protection into Circuits
When using communication interface chips in daily life, the circuit situation should not be overlooked. It is essential to appropriately configure circuit protection, especially when dealing with sensitive receivers like common RS485 chips, where protection based on sensitivity levels needs to be implemented. By introducing fault protection to the interface chip, it becomes possible to adjust output logic levels according to the actual situation. For example, a receiver may output a high level when the differential input voltage is zero volts but switches to a high level in case of a short circuit.
Outdoor Applications Require ESD Protection
Given the diverse types and wide applications of interface chips, proper electrostatic discharge (ESD) protection is crucial, particularly when outdoor use is involved. When interface chips are used for transmission lines, ESD protection measures need to be taken, such as using ESD-resistant chips or equipping them with human body model (HBM) ESD and machine model (MM) ESD protection, ensuring that these chips remain unaffected by static electricity during regular use.
Optocoupler Is Essential in Control Applications
Interface chips are often utilized in control devices, where considerations must be made for the potential presence of common-mode voltages among various nodes in the complex control system. Optocouplers play a vital role in isolating these connections. Taking the example of RS485 chips mentioned earlier, we can employ a DC converter to optically isolate the power supply of the earthing receiver, effectively eliminating the impact of common-mode voltages and preventing signal interference.
The factors to consider when using interface chips in daily applications have been discussed above. By taking these protective measures into account during practical operations, the overall user experience with the chips can be enhanced. Additionally, leveraging Unikeyicto select chips that better suit our requirements ensures optimal chip performance and stable operation.
