PPS Time Synchronization
On select FMADIO Devices have a PPS input connect that expect 1 1PPS 50ohm 5V signal. The start of second boundary occurs on the rising edge of the PPS clock. Required hold time is 100usec or more.
Enabling of PPS is automatic, when the system detects PPS input, it automatically selects PPS to discipline the timestamp clock.
PPS Timing provides highly accurate sub 10 nanosecond timing accuracy.
FMADIO Gen 4 systems PPS support is work in progress, please contact support@fmad.io for further information.
FMADIO Gen 3 systems fully support PPS
FMADIO Gen2 systems fully support PPS
