Soyuz Clock Part 7: Taming the Glitches in our Space Clock Crystal Oscillator
In this rather longish video we get to the bottom of the glitching issues we had seen in the crystal oscillator of our Soyuz space clock. Which gets us on a detour to reverse engineering a Soviet TTL chip, look at a quartz crystal on the VNA, and fight general RF electronic mayhem. 00:00 Glitch investigation 04:39 Inside a vintage Russian TTL chip 08:16 Quartz crystals and oscillators 21:15 Debugging the glitchy oscillator 32:44 Success and conclusion Ken Shirriff article on reverse engineering the Soviet TTL chip: http://www.righto.com/2020/03/looking...
