P3PS550AH Datasheet | onsemi

Description 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.

ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 5 of this data sheet. .. © Semiconductor ponents Industries, LLC, 2010 July, 2010 - Rev. 1 Publication Order Number: P3PS550AH/D VDD SR0 SR1 SR2 CLKIN Mod OUT PD# Figure 1. Block Diagram P3PS550AH modulates the output of a single PLL in order to “spread” the bandwidth of a synthesized clock, and more importantly, decreases the peak amplitudes of its harmonics. This results in significantly lower system EMI pared to the typical narrow band signal produced by oscillators and most frequency generators. Lowering EMI by increasing a signal’s bandwidth is called ‘spread spectrum clock generation’. Table 1. PIN DESCRIPTION Pin# 1 2 3 Pin Name CLKIN SR2 PD# Type I I I External reference clock...
