Hi,
Quick question: Can someone recommend a thru-hole crystal for use with the 16LF88 (one of the newer NanoWatt PICs with the low power optimized Timer1 oscillator). (Recommend a digikey part #?)
What I've figured out so far: Tolerance plus/minus 20 PPM ESR: 30 - 50 K max Max Drive level probably should be 1uW (which means that I probably need a series resistor to prevent overdriving the crystal) Load capacitance of crystal: 12 pF
- Are the above specs correct for selecting a crystal for Timer1 use?
- I don't understand the shunt capacitance parameter for crystals - from what I see on datasheets there's 1.00, 1.35, and 1.60 pF? Which one do I choose?
- Will be prototyping circuit on solderless breadboard - any problems with doing this? (I know that due to the low voltage/power levels as well as differences in capacitance etc things may be different).
Thanks Kevin.
