LPC2378 Ethernet Coonections

Started by sukhdeep singh June 15, 2011
Hi,
Can LPC2378 be directly connected with Ethernet Port through RJ45 Connector?if yes, how can?
I have read that RJ45 has
TX+,TX- for transmit.
RX+,RX- for receiver.

But LPC2378 datasheet has not shown any TX+,TX-,RX+,RX- for Ethernet connections.

Can anyone help me.

Thanks & Regards
Sukhdeep Singh

You need to use a PHY. Only a few microcontrollers have built-in PHYs, such as the Stellaris devices and some Freescale processors.

and Microchip :)
Olimex helpfully provide schematics of their LPC boards, which are a good example of how to connect up the PHY chip to the LPC and the RJ45.
