5PCS 1M 1MHZ 1.000MHZ Oscillator In-line Active Crystal OSC DIP-4 Rectangular Clock Vibration Full Size

None of the pieces worked.

I am using this to divide down to 1 HZ for a clock pulse, the accuracy and stability seems good. The actual part number i received was MCO-1510A. The footprint and the pinout is the same. It works OK with a 5V supply.
