content: Those look like WenzelSmall FryOCXOs, not "ULN" parts. They're still good oscillators but it's fair to call the pricing into question, given that there are a lot of other parts with similar performance.ULNs look like the one on this board:Not super common. They're about $2K-$3K brand new.

content: Another thing to note about these oscillators is that the 500 series part numbers have been modified to suit a particular customer's needs. Standard units use part numbers that start with 501.Wenzel won't give any info what has been modified so, in this case, the datasheet for the Small Fry oscillators can only give general guidance. For example, this oscillator has five leads while the standard Small Fry only has four. This could be a good thing, but has anything else been changed? Was the change an upgrade (e.g. lower aging), a downgrade (e.g. smaller temperature range), or just a change (maybe the extra lead is an oven monitor). There's no way to tell.

content: Quote from: bnz on November 10, 2023, 07:01:31 pmI never see any phase noise tester/Analyzer using the Taitien Quartz as reference, the aging rate is 1ppb/day (after 30 days), the Wenzel is 0.25ppb/day (after 30 days).
