I like to take as close to orthorectified photos of the PCB as possible and then align the pinout diagrams from the datasheets to see if anything matches. So far no luck on any of the HDMI interfaces in QFP-128 packages from the usual sources.
@th what board is that?
@quixoticgeek @th if it didn’t have the scratches, maybe we’d know. :P
@th not only that, they're scrubbed all the numbers off the capacitors!
@miek the IT6604E is an excellent guess! other than the pin 26 NC, everything else seems to line up correctly for the HDMI TDMS input pairs and the 10-bit RGB parallel output.
@th Perhaps the die reveals something after an X-ray photo.
@th Scraped the markings off *and* put gunk over that 6-pin chip (I assume containing firmware?)... Very impolite, indeed...
@th Something covered by export controls, embargo, or usage within munitions?
Clearly a case where the hardware and their component suppliers would prefer some little anonymity.
@HoffmanLabs @th HDMI and USB2= Certainly not embargoed.
Just the usual annoyance intended to cost an adapt reverse engineer 5 minutes (and the rest of us, a few days at most) to find out the parts.
@th what jerks. What possible legit reason is there for that?
It's not an SII1127AC or ADV7619 based on the NC pins and TDMS inputs.
