Why this edge matters
TSMC (leader in Foundry) is a tracked supplier of SiTime (leader in Analog, Power, RF). World's dominant foundry, manufacturing nearly all leading-edge chips. Leader in MEMS-based timing devices replacing quartz oscillators. The edge is one of 2 tracked suppliers of SiTime and one of 98 tracked customers of TSMC.
Source: derived from both company records and the counted edges.
Concentration / risk note
TSMC is positioned as a leader in Foundry, so this edge is harder to replace than a challenger or niche supplier. SiTime has only 2 tracked suppliers in this dataset. Concentration on the supplier side is high.
Basis: supplier position, few suppliers. Omitted on edges where the graph does not back a concentration claim.
