PCI-e Timing Card | Industrial High-Precision Timing Board

The PCI-e timing card is an expansion board integrating high-precision clock source, multi-source timing decoding and bus synchronous output functions. It can be directly inserted into the PCI-e slot of equipment without external power supply, and realizes time signal parsing and synchronization via hardware logic, delivering remarkable advantages over software timing solutions:

Ultra-high synchronization precision: Hardware-decoded timestamps achieve synchronization accuracy of ≤30ns, far superior to the millisecond-level precision of NTP, meeting stringent timing requirements for high-frequency trading, fault tracing and industrial coordination.

Low latency & zero jitter: Direct transmission over the PCI-e bus eliminates delays caused by network forwarding and system scheduling. The time signal remains stable with no jitter to guarantee consistent timing for critical services.

OS-independent operation: It runs separately from the operating system and maintains precise time synchronization even under system stuttering or heavy load, suitable for 7×24-hour non-stop operation.

Easy deployment & maintenance-free: Plug-and-play via standard PCI-e interface, compatible with full-height and half-height form factors to fit all types of servers and industrial control chassis, streamlining deployment procedures.

Core Advantages of Saisi PCI-e Timing Cards

1. Multi-source Redundant Timing for Complex Networking

The PCI-e timing card supports input of multiple types of external time sources, automatically identifying and switching to the optimal signal source to ensure uninterrupted timing:

Network timing: Compliant with PTP (IEEE 1588v2) protocol, supporting electrical and optical port access for precise time synchronization networks.

Hardware signal timing: Accepts IRIG-B (DC/AC) code and 1PPS+TOD pulse signals for connection with various time synchronization equipment.

Customizable priority configuration: Configurable switching logic for time sources, with satellites, networks and hardware signals complementing each other to prevent timing failure due to single-source outages.

2. Industrial-Grade Hardware Design for Stable Operation in Harsh Environments

Engineered with high reliability to cope with complex working conditions including industrial sites, computer rooms and transformer substations:

Onboard high-stability clock: Equipped with a built-in high-precision oven-controlled crystal oscillator (OCXO, high-stability version optional). In case of external signal loss, the autonomous timekeeping error is ≤1μs per 24 hours to sustain stable timing.

Wide temperature range & anti-interference performance: Built with industrial-grade components, operating within -40℃ to +85℃. The full metal shielding structure delivers strong resistance to electromagnetic interference.

Standard form factor compatibility: Available in full-height (168×89mm) and half-height (168×69mm) sizes, compatible with all 19-inch chassis and embedded devices.

3. Diverse Output Interfaces for Versatile Scenarios

The card supports both internal system timing and external reference clock output to flexibly meet diverse networking demands:

System timing: Delivers precise time to the host OS and applications via PCI-e bus, compatible with mainstream systems including Windows, Linux and QNX.

Signal output: Onboard interfaces for 1PPS pulse, IRIG-B code and 10MHz frequency output. It can act as a local master clock to provide time reference for peripheral devices.

Software compatibility: Rich APIs and driver programs are provided to support secondary development for customized timing applications.

4. High Integration & Low Power Consumption for Energy-Efficient Deployment

Adopting a dual-core FPGA+ARM architecture, the card features high integration and low power consumption (<6W) with no extra power input required. It cuts equipment energy consumption and heat dissipation pressure, ideal for high-density cabinet deployment.
