Terminal termination of high speed PCB

Posted on September 21, 2018 by G

In high-speed PCB digital circuit systems, impedance mismatch on the transmission line will cause signal reflection and signal distortion such as overshoot, undershoot and ringing, and when the delay TD of the transmission line is greater than 20% of the signal rise time RT, the reflection The impact can't be ignored, or it will bring signal integrity problems. The method of reducing the reflection is: matching the source impedance with the transmission line impedance according to the characteristic impedance of the transmission line at the driving end thereof, or matching the load impedance with the transmission line impedance at the receiving end, so that the source reflection coefficient or the load reflection coefficient is zero.

The current worldwide demand for environmental protection has made electronic products more demanding in the miniaturization of the Ministry of Energy. This has also spurred the advancement of high-speed and large-capacity electronic products for data and information processing. On the other hand, IT products that are personally demanded are also moving toward functional integration, high-performance (high-speed), and low-consumption power. In the signal transmission mode of electronic products, the parallel transmission mode develops toward a continuous mode. And the way in which optical transmissions have been added to electrical transmissions has begun to emerge. The high integration and high frequency development of electronic components has led to a continuous increase in the demand for high-frequency printed circuit boards.

How to strengthen anti-interference ability in PCB design

Posted on September 10, 2018 by G

To get the best performance from an electronic circuit, the board is the support for the circuit components and devices in the electronics. Even if the schematic design of the circuit is correct and the printed circuit board is not properly designed, it will adversely affect the reliability of the electronic product. When designing a printed circuit board, it is important to use the correct method, follow the general principles of PCB design, and conform to the requirements of the anti-jamming design and the layout of the wires. In order to design a PCB of good quality and low cost, the following general principles should be followed:
