This application note provides key recommendations for implementing serial communication systems that exceed IEC immunity test standards. To provide an example of highly reliable serial communications system implementation and testing, a Texas Instruments DP83640 Ethernet Physical Layer device was tested for International Electrotechnical Commission (IEC) immunity test compliance. Results from the

Texas Instruments PHYTERВ® family of products incorporate the Reduced Media Independent Interface (RMII) as described in the RMII revision 1.2 specification from the RMII Consortium. This interface may be used to connect a PHY device to a MAC in 10/100 Mb/s systems using a reduced number of pins relative to standard MII. In this mode, data is transferred two bits at a time using a 50 MHz refere

This application note first provides a summary of empirical results found when master to slave node synchronization is measured with Synchronous Ethernet mode enabled. Background information is then provided describing the operation of and topological constraints associated with Synchronous Ethernet mode. Typical applications are then described, followed by empirical data which clearly demonstrate

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

This application report describes a method of synchronization that provides much more accuratesynchronization in systems with larger PDV. The method described attempts to detect minimum delays, or'lucky packets'. The method also takes advantage of the DP83640 clock control mechanism to separatelycontrol clock rate and time corrections, minimizing overshoot or wild swings in the accuracy of t

The use of a reference clock that is less stable than those directly driven from an oscillator may be required for some applications. In addition, some customer applications may require partnering with devices that operate outside of the IEEE 802.3 standard for transmitted jitter.
