Altium pcb library6/19/2023 ![]() Even if a PDN supplies a voltage to the devices within tolerance, the PDN noise may still cause other problems. When the magnitude of the noise on PDN exceeds a certain threshold, it alters the voltages delivered to the ICs below the acceptable values, causing malfunction of the circuits on the board. PDN noise is injurious to the proper functioning of the board in several ways: ![]() #PowerIntegrity and #PowerDistributionNetwork
