Key Features

  • PCS3P2191A www. DataSheet4U. com 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 t.
