I kinda wish I was born in the 1980s so I could figure out some of the early CMOS circuits as a grad student

@jwt0625 I hope not because I am a victim of crosstalk

made a full high level visual with (codex claimed) consistent data stream across the panels.
ofc the eye diagram has fake transitions but it looks pretty good!

serdes experts, did codex do a good job?

Will be in the Bay Area from May 28th-31st, DMs open if you want to meet

if you are a 2nd year phd doing silicon photonics, chances are you enjoy microring resonators.
if you are a 2nd year system architect for optical comm, chances are you hate microring resonators.

@vikramskr Yep, they compiled the Avengers of SerDes in this authors list haha

Consider this essential reading if you want to understand interconnects.

@samhcarter For sure, he’s made the case against copper at very short distances at multiple conferences this year.

shit is Andy Bechtolsheim an optics bull now?!
Fabian@iamfabian
You guys need to hear what Andy Bechtolsheim said at OFC regarding the amount of optical transceivers that he expects to be manufactured and shipped in the coming years. Optical transceiver manufacturers are all at full capacity and expanding, and you are confident enough to call the top on optics and photonics? Same applies to all the DSP manufacturers, like just look at $MXL as an example and the DustPhotonics acquisition by $CRDO. Have a nice Sunday!

@insane_analyst High resolution in 4 quadrants :ppp

@phasentrpolator Phase interpolator no longer spinning and unlocked

@vikramskr Congratulations Vikram! It’s been a pleasure seeing you grow on Twitter and Substack from the start. Wishing you good luck on this transition!

Personal update.
The start of something new.

I have in my possession the Wolfspeed 10KV SiC part datasheet.
Plan is to design some simple DC-DC converters using that part and next best Infineon 2KV rated part.
I am terrible at analog design and this will take time. Also need to get Cerebras report out before they IPO.
