Hi guys,
I'm using a cheap, can-type clock oscillator in a project as a frequency standard. It's 10 MHz. Here's the specs:
What I don't understand is that in the literature they say that the frequency stability is only +/-100 ppm. If I'm figuring right, that means that the clock can vary per second by as much as +/-1000 clock ticks. But when I connect the output to a frequency counter it reads
10,000,060 Hz and only fluctuates maybe one or two ticks over time, which is orders of magnitude better than what they claim.Did I just get lucky, or am I misunderstanding the specs? Is this an average error over a batch of many parts? Are they taking the entire temperature range into account? What gives?
Thanks.
Sid
