JN5168 (and other in the family) have quite strict requirements regarding 32MHz crystal to be used - low ESR or low capacitance. These can be achieved with large footprint crystals like 3.2x2.5mm crystal used in JN5168 Mxx modules or USB dongle. I am however very constrained in PCB space and I'd like to use smaller device instead, e.g. a silicon or crystal oscillator like this: http://docs-europe.electrocomponents.com/webdocs/12e7/0900766b812e7646.pdf . Datasheet says I can use external source for 32kHz clock but says nothing about other source than crystal for 32Mhz clock.
Can I use JN5168 with such devices instead of crystal? How do I connect it? Just directly to XTALIN and leave XTALOUT not connected?
