Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~
People should find solutions to problems, not find problems with solutions.

Have you guys looked at the IDT QuickSwitch devices?Smonson wrote: ↑Sat Sep 01, 2018 10:52 am74LVC245A

Seems plenty fast according to that spec sheet, unless I'm misunderstanding something.Smonson wrote: ↑Sat Sep 01, 2018 10:52 am74LVC245A

Re: Project: HDMI/DVI out for STFM
I think it was just a suggestion..Nothing wrong with those of course.
For my stuff, I am pushing every MHz out of everything, so the IDT switches have pretty much zero delay, which is what I need. In case of the FPGA stuff, a few ns isn't going to make any odds. Though I guess the IDT stuff may be easier to solder as they (IIRC) are larger packages.

Re: Project: HDMI/DVI out for STFM
The only reason I mention the buffer is that the one I used for the 16MHz line (M74VHC1GT125DF2G) can't hack it at 32MHz. Since 16MHz is not too fast by today's standards I didn't worry about it when selecting buffers.
Re: Project: HDMI/DVI out for STFM
May I suggest the NB3N551 for clock buffering :

Working ones : MegaSTE (68020) / TT030 / Falcon with AB040 & Eclipse / 1040STF
Need testing : Falcon with CT2

Re: Project: HDMI/DVI out for STFM
Suggestions are welcome. But from the datasheet it looks like this device is only guaranteeing to produce a 2.4v high. Dunno if the Atari would be too happy with that.
But this is definitely the kind of thing I should have used in the first place
