02:24 <Degi> Looks like we can forget about HMCAD1511/1520 for 2022

02:26 <Degi> AD9690 sounds fun

02:55 <azonenberg> Degi: oh?

02:55 <azonenberg> are they already sold out into 2023?

02:55 <Degi> Well the one I can find is start of 2023 on Mouser, at least Mouser and Digi-Key are sold out with 52 weeks lead time

02:56 <azonenberg> Lovely

02:56 <Degi> Hm yes, 16/02/2023

02:56 <azonenberg> I have four HMCAD1520s in inventory in my lab, planned for a single channel prototype of the original 4x HMCAD1520 interleaved ZENNECK

02:56 <Degi> Apparently LCSC has 5 left

02:56 <azonenberg> So I could do something with them. Or if someone has a legitimate need in the near term, I might be willing to part with them for the current digikey list price

02:57 <azonenberg> (at least one or two, probably not all)

02:57 <Degi> According to OctoPart this dubious site has 1002 http://rfq.rxicsource.com/h5/#/pages/rxicsource/quote?part=HMCAD1511

02:58 <Degi> iodparts and winsource say they have 1000 each in stock but winsource is a bit pricy and iodparts wants rfq

02:59 <Degi> Also Ebay has some, even cheaper than mouser, I wonder if they'd actually arrive https://www.ebay.de/itm/353735056795

14:22 <someone-else> Degi: try here: https://www.aliexpress.com/wholesale?SearchText=HMCAD1511&opensearch=true

14:22 <someone-else> worst case if there's no stock they'll just refund you

14:23 <someone-else> most likely these small sellers access the same stock which is listed on winsource.com

14:23 <someone-else> but prices might be better

14:24 <someone-else> also, I have a couple of HMCAD1511s bought from lcsc when they were $16.3846 each

14:25 <someone-else> don't have a plan to use then anymore (300MHz FPBW meh), so they can be yours if you have

14:26 <someone-else> wow, they're $97.0038 each now on lcsc

14:27 <someone-else> holy supply and demand batman

14:35 <azonenberg> someone-else: digikey price in the Before Times was something like $60-70

14:35 <azonenberg> and the 1520 was a bit over $100, maybe $110ish?

14:36 <someone-else> yep, there was a glut of HMCAD1511s no one wanted in China hence the $16 price

14:36 <someone-else> now there's shortage

14:37 <someone-else> or maybe not, they're just hoarding the same reel just in case

14:39 <someone-else> HMCAD1511s are used in lot of low-end Chinese scopes

14:39 <someone-else> HMCAD1520s aren't so they weren't as available

14:45 <azonenberg> I'm honestly surprised more of the cheap scopes don't have a slightly more expensive 12 bit mode

14:45 <azonenberg> the 1520 is pretty much drop in compatible with the 1511 given new firmware

14:46 <azonenberg> you could make an alternate stuff of the same board and sell it for quite a bit more

14:46 <azonenberg> are their frontends just so crappy that they can't benefit from the extra resolution because there's so much noise?

14:47 <someone-else> perhaps were wasn't enough margin for the more expensive 1520

14:48 <someone-else> I wonder if anybody did actually do the upgrade themselves

14:48 <azonenberg> You'd have to rewrite / patch the FPGA firmware

14:49 <azonenberg> while you could drop in the chip easily with hot air, it would function like a 1511

14:58 <someone-else> yeah, quite a bit more difficult than just swapping the ADC

17:52 <azonenberg> AKL-PT5s are at my local fedex hub coming today or tomorrow woop

18:29 <azonenberg> And it's out for delivery
