1 MHz crystal options

[netdudeuk]

Hi

I need a 1 MHz crystal for use with a SFC96364 VDU chip.

The only easy / cheap options seem to be either oscillator modules or ceramic resonators.

I'm thinking that you can't just put the two output pins of a module across the crystal pins on the IC.  Right ?

Would a ceramic resonator be good enough ?

Thanks

It might be possible to feed the oscillator module output into one of the crystal pins.

Figure 2 and 3 in this article:

https://www.analog.com/en/resources/technical-articles/replacing-crystals-and-ceramic-resonators-with-silicon-oscillators.html

shows the basic idea. Using an oscillator you just feed the output into one of the crystal pins and leave the other one open.

It might matter which one you feed the signal into.

It certainly will matter. Feed oscillator into pin 1.

Thanks both.  @ledtester, I really appreciate that article you linked to.  I shall read it now.
