content: I've received oscillators,https://www.arrow.com/en/products/lftcxo063713bulk/iqd-frequency-productsInitial test shows 0.02 ppm tolerance (measurements with NEO-7 gps module).Compare to digikey price for the same items, I get them almost freehttps://www.digikey.ca/en/products/detail/iqd-frequency-products/LFTCXO063713BULK/8633973?s=N4IgTCBcDaIDIDEAqBhAGgeQAwDYDMA7AIx4BCAqnANIgC6AvkAGonna to check on temperature stability.

content: Thanks for the tip, I received 5 pieces in a gigantic box for $8.01 with free shipping to the Netherlands.Not sure how these guys make a profit

content: How many did you buy? Seems its gone now.Any plan to make a mini USB 10MHz reference board or something.

content: I've got 2, there was not many, 6 or 7 items. Likely "clearance", though not seen this label on arrow. Occasionally they put "reduced price" .Also received MOSFET'shttps://www.arrow.com/en/products/rm110n85t2/rectron- couldn't resist such good offering. Now have to design high current DC-DC converterI like this practice on arrow, may get my hands on something, that I 'd not buy otherwise.Regarding TCXO, my gps test on 2-days long frequency stability shows 0.08 Hz deviation with day/ night temperature shift. Can't say more precise in Hz/ Celsius, but very impressive compare what I ever seen before working in telecom

content: Quote from: MasterT on July 28, 2020, 09:05:17 pmYeah, its good, but no way to directly search for these items that I am aware of.Compare this to Digikey, who probably lets some items stay in inventory for decades?

content: A TCXO is not an OCXOA few years ago I got a frequency counter that contained a TCXO (and a pretty good one considering) it was not much more than $8.But in smaller quantities they can be pricey.

content: One 'lovely' trap with modern TCXOs is that sometimes the compensation is a temperature sensor driving a lookup table in a little toy processor which then controls the tuning via a DAC....Result is discrete steps in the frequency as you vary the temperature! Yea, it meets spec, but that can be a very unwelcome surprise.
