Precision Timing: The Silent Dependency in High-Reliability Systems

Timing failures rarely announce themselves. A clock does not go down the way a power rail or a comms link does. It drifts, it wanders under vibration, or ages out of tolerance, and the symptoms surface somewhere else: a control loop that loses repeatability, a network that resynchronizes more often than it should, an intermittent fault nobody can reproduce on the bench.

That is the nature of a silent dependency. Every control loop, sensor fusion stack, and synchronized network rests on the assumption that the clocks agree and keep agreeing. The assumption is almost never examined until a failed downstream node forces the question.

Automotive, industrial, and aerospace systems make that dependency unusually demanding: holding performance for decades, in the field, with no realistic chance to service the part. That inverts the instinct carried over from consumer design, where a strong number at nominal conditions over a short life is enough.

This session introduces SiTime and how we approach precision timing as a system solution rather than ‘just a clock’.

Attendees will leave with:

• Why timing degradation presents as someone else's failure

• What environmental stress does to a time base over years, not minutes

• What separates a timing component from a timing solution

• How SiTime approaches these markets

The session closes with live Q&A.
