Overview

The W147G is a highly integrated frequency timing generator, supplying all the required clock sources for an Intel? architecLButtonture platform using graphics integrated core logic.

Features

? Maximized EMI suppression using Cypress’s Spread Spectrum Technology

? Low jitter and tightly controlled clock skew

? Highly integrated device providing clocks required for CPU, core logic, and SDRAM

? Three copies of CPU clock at 66/100 MHz

? Nine copies of 100-MHz SDRAM clocks

? Eight copies of PCI clock

? Two copies of synchronous APIC clock

? Two copies of 48-MHz clock (non-spread spectrum) optimized for USB reference input and video dot clock

? Two copies of 66-MHz fixed clock

? One copy of 14.31818-MHz reference clock

? Power-down control

? I2C interface for turning off unused clocks
