Time Synchronization Accuracy:

It is an important indicator to measure the board, which refers to the time deviation from the standard time source after the board achieves time synchronization. For example, the accuracy can reach nanoseconds, and the timing accuracy has different levels such as better than 20ns and 30ns.

Timekeeping Accuracy:

When the external time base is interrupted, the board relies on the internal clock source to maintain the time accuracy, which is usually expressed as the amount of time drift within a certain period of time, such as a few microseconds drift per day.

Supported Interface Types:

Including Ethernet port, serial port, 1PPS interface, SCSI interface, etc., used for connection with other devices and time signal transmission.

Operating Temperature Range:

Generally -20℃ to 70℃, special application scenarios have wider or narrower temperature range requirements.

Input Signal Type:

There are satellite signals, B code signals, PTP signals, etc. Different signals are used for different time synchronization methods and application requirements.
