ADCs with built-in very fast conversions (1-2uS), externally triggered by precision tunable oscillators, these (across different boards) frequency locked by very slow, averaging FLLs. Phase may be skewed but frequency should be held. > Upsampling to 192k at the receiving end to better hide the > skipped/inserted samples might be an idea.
