Avoiding Pitfalls in High-Speed PCB Design: 7 Key Aspects (Layer Stacking / Layout / Impedance Control Explained)

Avoiding Pitfalls in High-Speed PCB Design: 7 Key Aspects (Layer Stacking / Layout / Impedance Control Explained)

The biggest challenge in high-speed design is to minimize crosstalk, ensuring good signal integrity during transmission while also reducing the impact of noise on the PCB. Since single-ended signals and Low Voltage Differential Signaling (LVDS) are typical types of high-speed interface signals, it is essential to ensure the transmission of these two types of signals.In … Read more

LVDS Technology and Its Application in FPGA

LVDS Technology and Its Application in FPGA

Currently, digital video in circuits uses the Camera Link interface for transmission. The previous solution involved the FPGA outputting parallel data signals along with synchronization control signals, which were then processed by the serializer chip DS90CR287 to convert parallel to serial. After processing, the output was sent through the Camera Link interface, with the capture … Read more

4G and 5G Are Not Suitable for IoT, Yet They Persist

4G and 5G Are Not Suitable for IoT, Yet They Persist

The Internet of Things (IoT) is a key technology that will determine the future economy. The ubiquitous interconnection of all things will eventually become a reality. However, achieving ubiquitous IoT coverage is not that easy. IoT technologies such as ZigBee, 6LoWPAN, or IEEE 802.11ah are only suitable for short-range IoT coverage and cannot guarantee reliable … Read more
