I want to go hunt the upper limits of the P2’s non-PLL speed capability, but I lack a suitable clock source. Tonight it hit me that I might be able to use the tracking generator from my spectrum analyzer for this task. The output does -20db to 0db, which from my understanding, if capacitively coupled to XIN, should be in the normal crystal range.
Am I milking without a bucket here, or would this be workable? I’d really want to see how far the P2 can be pushed with the PLL out of the way.
