DP83849I Link unstability on Freescale K70

Other Parts Discussed in Thread: DP83849I

Hi

I am using DP83849I PHY for TWR-K70F120M Platform on TWR-SER2 board.

When my application goes up, and i try to ping the IP Address,

I observe a "request times out." message after random time repeatedly. This message appears after random pings requests.


I have googled and found that "National Semiconductor DP83849I Ethernet PHY deprecated because of large
link loss reaction time and delay". Is it right? If no, what would be possible cause of link loss

Regards
