[quote user="APOORV GARG"]", for which component pin nos 4,5,6 and 7 are you talking about?[/quote] The Ethernet out RJ45 jack and check again I edit post 75 ohm Bob Smith terminator has 1000pf/2kv cap to some ground point. [quote user="APOORV GARG"]There are no 2 separate ground FGND and AGND in my schematic. [/quote]. Technically the fork shaped ground symbol is considered frame/chassis ground and the lined ground symbol is analog ground plane back side of 2 sided PCB. Triangle shape is digital ground often tied to analog ground somewhere through VIA on top side PCB. Datasheet NCPDT Figure 20-13 may differ from ENCPDT, from my limited understanding ENCPDT is different in 256kb data encryption support is built into EMAC0. Charles might be better to explain any difference that might effect the Bob Smith terminator on the pulse transformer between MCU types. My guess there is very little if any difference (Bob S.) unless ENCPDT adds Gigabit over copper wire.
