PCS3P2191A
www.DataSheet4U.com output. PCS3P2191A offers seven selectable centre
spread options of ±0.5% to ±2.0%, and a no spread option. (Refer Spread reduces Deviation Selection Table). PCS3P2191A electromagnetic interference
Generates four 4X low EMI spread spectrum clocks Input frequency: 15MHz Output frequency: 60MHz Internal loop filter minimizes external components and board space Selectable Centre Spread frequency deviation: ±0.5%, ±0.75%, ± 1.0%, ± 1.25%, ± 1.5%, ± 1.75% ± 2.0%
(EMI) at the clock source, allowing system wide reduction of EMI of all clock dependent signals.
