Abstract

Embodiments relate to identifying frequencies to be protected at a victim integrated circuit (IC) and sending protection information including the identified frequencies to an aggressor IC. The aggressor IC configures its subsystems or circuits to operate using operating frequencies that prevents spurs that may interfere with the frequencies identified in the protection information. If not all of the frequencies in the protection information can be protected, the aggressor IC selects a subset of the frequencies to be protected. Then, the aggressor IC configures the operating frequencies of its subsystems or circuits so that spurs that they generate do not interfere with the selected frequencies.
