onsemi P3PS550AH
The P3PS550AH is a versatile 2.3 V to 3.6 V, Timing−Safe™, high drive spread spectrum frequency modulator designed specifically for a wide range of clock frequencies. The P3PS550AH reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of all clock dependent signals. The P3PS550AH allows significant system cost savings by reducing the number of circuit board layers ferrite beads, shielding that are traditionally required to pass EMI regulations.| Part No. | P3PS550AH |
