I am considering using SiT8008 devices from SiTime. They are low power wit h good specs for simple digital clocking. I can't tell anything about avai lability. Digikey carries them, but don't show inventory listing them as " Value Added Item". I think they have unprogrammed devices which have to be programmed before shipping. They are only asking $1.23 for qty 1, so I gu ess the programming is tied into the ordering process so there is no hand l abor involved.
But I am left not knowing what sort of delivery or what inventory they may have on these. Adding 10,000 to an order seems to go without a problem, bu t it doesn't mean they have any in stock. It says if I order and there's a problem with delivery they will let me know. lol
Then there's also a letter in the part number the data sheet simply says is "revision" but Digikey has both A and B rev parts. What's the difference and how do I get data on it?
I guess they expect a salesperson to be involved.
