Block Diagram

General Description

The ICS9LPRS436C is a low power CK505-compatible clock targeted at Intel-based Netbooks and Nettops. This clock synthesizer

provides a single chip solution for systems using the Intel NM10 chipset paired with the Intel N450/D410/D510 Atom

ICS9LPRS436C is driven with a 25MHz crystal.
