The PPS width and interval are programmed in terms of granularity of system time, that is, number of the units of sub-second increment value.
The PPS width and interval are programmed in terms of granularity of system time, that is, number of the units of sub-second increment value. For example, to have a PPS pulse width of 40ns and interval of 100ns with PTP reference clock of 50MHz, program the width and interval to values 2 and 5, respectively. You can achieve smaller granularity by using a faster PTP reference clock.
Before giving the command to trigger a pulse or pulse train on the PPS output, program or update the interval and width of the PPS signal output.
