Application Notes

The DP83640 provides a highly precise low-jitter clock output that is frequency-aligned to the masterIEEE 1588 clock and can be phase-aligned as well. Empirical testing shows very low jitter (less than 1 nspeak-to-peak and standard deviation when using the FCO source) and precise phase alignment. Whiletest results show that the FCO has superior long term jitter performance using the PGM as
