. . . que je traduis par "horloge à étalement de spectre" (?)

Bonjour !

En triant je trouve un circuit -> https://www.ti.com/lit/ds/symlink/cdcs502.pdf
Dans quelles applications est-il intéressant ?

Oui c'est la bonne traduction, c'est pour les dispositifs électroniques qui ont besoin de clock mais qui veulent/doivent minimiser leur EMI.
Un exemple historique assez parlant illustrant le besoin:

A good example of the motivation behind these regulations occurred years ago at Dallas/Fort Worth Airport. Pilots, during takeoffs and landings, reported loss-of-control situations with recently developed electronic flight-control systems. The FCC traced the cause to interference from remote-controlled garage-door openers in homes in the surrounding suburban areas. The Part 15 regulations addressed this problem by requiring that all electronic equipment sold in the U.S. be tested and certified to ensure against radiated RF energy that could cause malfunctions in other electronic devices.

Merci.

Je me demande pourquoi j'ai acheté ce truc (il ya une vingtaine d'années).
