This oscillator provides clock to an FPGA which powers the ultrahdmi mod for an N64 (https://www.retrorgb.com/ultrahdmi.html). It's clearly marked A03ZZ 1414
Clock output is diametrically opposite pin 1, it's a 4 pin device, it takes a 3.3V supply. Dimensions are nominally 3.2mm by 2.5mm
When I scope it with my limited equipment I get a weak ~75MHz signal (50mv p-p), but that could be junk from a number of sources.
The story behind this: it came to me with a glitch where it would lose on screen display functionality over time. Careful application of compressed air suggested the oscillator was the culprit, so I tapped it with the soldering iron on all 4 corners - now the device simply doesn't work. I've since fixed the bridge between the land and the exposed leadframe to no avail. I'd like to try replacing this part with something as close as possible, but if we fail to identify it SMD oscillators are cheap enough that I'll buy a spread of spectrum and try em all if I have to.
