The P278XA is a versatile spread spectrum frequency modulator designed specifically for digital camera and other digital video and imaging applications. It reduces electromagnetic interference (EMI) at the clock source, which provides system wide reduction of EMI of all clock dependent signals.
The P278xA family (P2781, P2782, P2784) is a spread‑spectrum frequency modulator designed for digital video, imaging and other clock‑sensitive applications. It reduces electromagnetic interference by spreading the clock spectrum, providing up to 15 dB of EMI suppression and zero‑cycle slip at low spread percentages.
