PCI-e timing card | Industrial grade high-precision timing card

　　In terminal scenarios such as servers, industrial computers, and embedded devices, PCI-e timing cards (also known as timing boards) are the core expansion components for achieving high-precision time synchronization within the device's internal hardware. They are directly connected to the device motherboard through the PCI-e bus, providing nanosecond level standard time reference for the system and solving the pain points of high latency and insufficient accuracy in traditional network timing (NTP) software. Zhejiang Saisi Electronic Technology Co., Ltd. has launched a high-performance PCI-e timing card, which has become the preferred timing card for industrial control, data centers, financial transactions, power communication and other scenarios due to its high integration, high precision, and strong adaptability.

　　1、 PCI-e timing card core value: hardware level timing, dual improvement of accuracy and stability

　　The PCI-e timing card is an expansion board that integrates high-precision clock sources, multi-source timing decoding, and bus synchronization output functions.
