Differential Signaling In the field of electronic communication and signal transmission, “differential signaling” is a frequently encountered technical term. From USB data cables and HDMI video cables to automotive CAN buses and industrial Ethernet, it relies on this method to achieve stable data transmission. The core logic is quite simple — using “comparison” instead of … Read more
Welcome FPGA engineers to join the official WeChat technical group Clickthe blue textto follow us at FPGA Home – the best and largest pure FPGA engineering community in China LVDS stands for Low-Voltage Differential Signaling.

Source | https://blog.csdn.net/lxm920714/article/details/107942572 Recently, I designed a new board using the Spartan 7 chip to overlay an OSD menu on the front-end video source. The front-end converts HDMI to LVDS for the FPGA to process. During the schematic design phase, I did not carefully read the FPGA manual, which led to incorrect power supply for … Read more
We often use touch screens and hear about various touch screen interfaces, such as LVDS, EDP, and MIPI. So, what are the differences between them?Let’s take a look. LVDS, EDP, and MIPI are three mainstream high-speed data transmission interfaces primarily used for display and video signal transmission, but they have significant differences in design goals, … Read more
Hello everyone, I am Pi Ge! Have you ever wondered how mobile phone screens display images? How do televisions receive high-definition signals? How does an industrial control screen communicate with the system? The answer lies in various display interface technologies! Common display interfaces, such as LVDS, DSI (MIPI DSI), and HDMI, may seem like mere … Read more
Recently, while debugging the display issues in OpenHarmony, the cause was identified as the hardware being connected via HDMI to an RK628 adapter, which in turn connects to an LVDS display. The display panel implementation in OpenHarmony is relatively simple, directly using a DSI panel. Therefore, it is necessary to thoroughly organize the relevant drivers … Read more
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
01 eMMC Signal Impedance and Routing It is recommended to use ground wrapping for CLK and STRB signals, with a ground via every ≤500 mil. During overall layout,eMMC should be placed as close to the SOC as possible to minimize routing length. The reference layer for all eMMC signals must be a complete ground plane … Read more
