ICS9LPRS436C
Low Power Clock for Intel Atom^®-Based Systems
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^® CPUs. The
ICS9LPRS436C is driven with a 25MHz crystal.

Notes:
1. Preferred drive strengths using CK505 clock sources. Transmission lines to load do not share
series resistors.
2. Desktop/Mobile Platforms with Zo = 50/55 ohms use the first resistor value.
3. Systems with Zo = 60 ohms use the resistor values in brackets [ ].
