I am designing a circuit I am planning to have fabricated that uses the W5500 Ethernet IC. I am quite new when with this and I've heard of a number of people having problems with the crystal (bad tuning, no start, etc.) that goes with the W5500.
I need to get this circuit working on the first try (not enough time to iterate) so I was wondering if I could use an oscillator in it's place to avoid potential problems. My understanding is that they are pretty much guaranteed to work albeit at a higher cost.
How would an oscillator be connected to the W5500? Should I just connect the oscillator output to CLKIN? Does the oscillator replace the crystal and capacitors or also the 1M resistor (R14)?
These are the W5500 crystal requirements:
Would this oscillator be good for the W5500? Is its output compatible with the levels expected by W5500's CLKIN?
I am an idiot, just got the answer for the first question from the W5500 datasheet:
The oscillator I referenced seems to have a CMOS output instead of TTL output so I suppose it won't work.
Can I use a CMOS oscillator with a device that expects TTL clock in?
EDIT: Would this TTL/CMOS compatible oscillator work with the W5500?
