TrueTime GPS-VME 560-5622 Circuit Board
Product features (5 items)
6U VME plugin card provides precise time to VME bus computers, ranging from microseconds to thousands of years.
It can operate independently as a generator or synchronize with GPS systems or external IRIG reference signals.
In GPS synchronization mode, the accuracy of UTC is better than 1 microsecond, and the position accuracy is about 25 meters.
The time data is provided to the VME bus in 5 16 bit BCD words, with zero read delay and no need to wait for the ready flag.
Equipped with dual time freeze register, programmable rate generator, four independent programmable interrupts, and dual time comparison function.
Product application areas (10 items)
High precision time synchronization of VME bus computer system.
An industrial control and data acquisition system that requires GPS timing.
IRIG-B time code generation and allocation.
External event timestamp.
Scientific research data records that require microsecond level timestamps.
