Today I had a look at VGA/DVI. I must say I'm a bit disappointed - try as I might, I didn't spot a single bug :-(
A few details, though: - U18 doesn't show the central pad's connection to ground. I suppose that's just something in the schematics ? U1 has the same issue. - the circuit around D5 looks confusing. How about rearranging it as shown at the bottom of http://downloads.qi-hardware.com/people/werner/tmp/style-0.pdf ? - we deviate from the reference design at one point, namely R142 where Analog Devices recommend 530 Ohm (figure 10) while we use 560 Ohm. I don't think that parameter is very sensitive, so I wouldn't expect this small difference to matter. And a quick return to audio: shouldn't things like LINEIN_DET and LINEOUT_DET also have TVS ? (Thinking of little arcs finding their way across airgaps and into the FPGA ...) - Werner _______________________________________________ http://lists.milkymist.org/listinfo.cgi/devel-milkymist.org IRC: #milkymist@Freenode
