Anti-jamming considerations for digital circuit design

Posted on September 26, 2018 by G

In the design of electronic systems, in order to avoid detours and save time, the anti-interference requirements should be fully considered and avoided, and remedial measures against interference should be avoided after the design is completed. There are three basic elements that form interference:

Analysis and Countermeasures of Power Supply Noise in High Frequency PCB Design Process

Posted on September 21, 2018 by G

Abstract: This paper systematically analyzes the various forms of power supply noise interference in high-frequency PCB boards and their causes. Through formula derivation and engineering experience, several corresponding countermeasures are proposed. Finally, the suppression of power supply noise should be followed. The general principle.

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.

(1) Cross circuit is not allowed in the printed circuit. For the lines that may cross, it can be solved by “drilling” or “winding”. That is, let a certain lead be "drilled" from the gap under other resistors, capacitors, and triodes, or "wrap" from one end of a lead that may cross. How to make the circuit complicated in special cases, to simplify the design It is allowed to bridge the wires to solve the cross circuit problem.

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:

Source synchronization timing relationship and simulation examples

Posted on August 30, 2018 by G

The so-called source synchronization means that the clock strobe signal CLK is transmitted by the driver chip along with the transmission data, and it does not use an independent clock source like the common clock synchronization. In the source synchronous data transceiving, the data is first sent to the receiving end, and the strobe clock is sent to the receiving end for sampling and latching the batch of data after a short time. The schematic diagram is shown in Figure 2. The timing analysis of source synchronization is simpler than the synchronization of common clocks. The analysis methods are very similar. The analysis formula is directly given below:
