P1819G: Notebook LCD Panel EMI Reduction IC
The P1819 is a Versatile Spread Spectrum Frequency Modulator designed specifically for input clock frequencies from 20 MHz to 40 MHz. The P1819 reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The P1819 allows significant system cost savings by reducing the number of circuit board layers ferrite beads, shielding and other passive components that are traditionally required to pass EMI regulations.
特性- Internal loop filter
- Generates a low EMI Spread Spectrum clock and a non-spread reference clock of the input frequency
- Selectable spread options: Down and Center
| 优势- Minimizes external components and board space
|
应用- EMI management for memory
- PC peripheral devices
| 终端产品- Consumer electronics, and embedded controller systems
