I'm running into a bizarre problem. When I use the integer output divider, 100% of the chips work. When I use the fractional divider, on about half of the chips (6 out of 12 tested), the output is off frequency and noisy. An oscilloscope shows almost noise-like glitches on the output, like the input signal to the divider was noisy. Has anyone experienced this?
I replaced the chip on one of the bad boards, and now it works great. Any helpful suggestions? Do I really have a 50% failure rate on these chips?
