If you absolutely require the original document, try contacting suppliers that specialize in legacy/obsolete components, such as: Bluetooth Version 5
The results were the usual graveyard of broken links: obsolete forum pages, Russian schematic dumps, and a defunct electronics supplier’s catalog from 2007. The VHM 314 was a ghost. A legendary, impossibly precise analog-to-digital converter chip from the late 80s, used in a single, now-mythical piece of Soviet test equipment. Finding its datasheet was a rite of passage for hardware archaeologists.
