PCS3P2191A

Spread Spectrum Clock Generator

Features

output. PCS3P2191A offers seven selectable centre

spread options of ±0.5% to ±2.0%, and a no spread

option. (Refer Spread Deviation Selection Table).

PCS3P2191A reduces electromagnetic interference

(EMI) at the clock source, allowing system wide reduction

of EMI of all clock dependent signals. The PCS3P2191A

allows significant system cost savings by reducing the

number of circuit board layers, ferrite beads, and

shielding that are traditionally required to pass EMI

regulations. The PCS3P2191A uses the most efficient

and optimized modulation profile approved by the FCC

and is implemented in a proprietary all digital method.

The Device is available in 16 Pin TSSOP package, in

Commercial and Industrial temperature range.
