16 MHz Crystal for prop

logan996

Found 16 MHz crystals for .49 cents each I think it might be possible to solder some small wires to them because they are smd, but they are full size with smd leads. I don't remember if the porp supposts 16 MHz crystals so please tell me if they do. Also i found this: 8-Bit Shift Register (Part# M74LS164P) Description: 8-bit serial-input parallel-output shift register from Mitsubishi (part# M74LS164P) features direct reset capability and an operating temperature range of -20 to 75 degrees Celsius. Recommended operating conditions: VCC=4.75V-5.25V, VIH>2V, VIL<0.8V. 14 pin DIP. Datasheet available. G17840 Would this be compatable with the propeller?

Hello,

The HC family, is less expensive, consume less energy, modern, etc.
Mouser Electronics has it for $0.19 x 1 (0.17 x 25)

Oh! 100% compatible with the Propeller.

16MHz xtals are way outside the propeller specifications. With the proper design we have been able to get the DIP prop to run using a 15MHz xtal by overclocking to 120MHz, but this is not recommended. The best I have been able to get a QFP prop to run at is 14.31818MHz xtal.

I see this component as an output device, but not for a keyboard input.
