I am designing a board with the W5300 chip and I am having a hard time finding a crystal/oscillator that meets the specifications outlined in the data sheet. I would like to get a fairly robust clock source because these boards will see a fair amount of extended mechanically noising environment and would like the Ethernet to continue to function. So any recommendations would be great.
If I used an Oscillator (Part number recommendations?)
I noticed that in order to use an oscillator I would need to connect it to XTLP and leave the XTLN floating. I noticed that it is recommended to use a 1.8V clock, is there a range that will work?
Also can I use the 1.8V power regulated from the W5300 chip or do I need a dedicated regulator?
I would prefer to drive the clock from my FPGA but it has a 3.3V output would this be in the functioning range?
