P1727 Description
The P1727 is a versatile spread spectrum frequency modulator designed specifically for a wide range of clock frequencies. The P1727 reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream (clock and data dependent signals).
