Crystal vs. TTL Clock ? What's the difference?
Hi,
What's the difference between a TTL Clock and a crystal? I'm curious to know if I can substitute a TTL clock (1 MHz specifically) for a crystal. Thanks for any info. Farce |

What's the difference between a TTL Clock and a crystal?
I'm curious to know if I can substitute a TTL clock (1 MHz specifically) for a crystal. Thanks for any info. It's been a while since I had a course on this but I think crystals are more accurate. |

Thanks for any info. --- A crystal is a slab of quartz which, by virtue of its piezoelectric nature, can be used to construct an oscillator. A TTL clock is just a device which can supply a clock signal at TTL voltage levels. You may be able to substitute a TTL clock for a crystal if the circuit driving the crystal is designed to allow it. Many circuits are. -- John Fields Professional Circuit Designer |

TTL clock runs all by itself, a crystal needs to be part of an oscilator, I'm curious to know if I can substitute a TTL clock (1 MHz specifically) for a crystal. Most probably (if the device attached to the crystal is compatble with TTL signals). the documentation for the device which the crystal is attached to will say which crystal pin is the input. connect that to the clock's output.
