W159规格书详情
Overview
The W159 is designed to provide the essential frequency sources to work with advanced multiprocessing Intel® architecture platforms. Split voltage supply signaling provides 2.5V and 3.3V clock frequencies operating up to 133 MHz.
From a low-cost 14.31818-MHz reference crystal oscillator, the W159 generates 2.5V clock outputs to support CPUs, core logic chip set, and Direct RDRAM clock generators. It also provides skew-controlled PCI and IOAPIC clocks synchronous to CPU clock, 48-MHz Universal Serial Bus (USB) clock, and replicates the 14.31818-MHz reference clock.
Features
• Maximized EMI suppression using Cypress’s spread spectrum technology (0.5 down spread)
• Seven skew-controlled copies of CPU and 16.667-MHz synchronous APIC output
• Two copies of fixed-frequency 33-MHz outputs
• Four copies of 66-MHz fixed-frequency outputs
• Two copies of CPU/2 outputs for synchronous memory reference
• One copy of 48-MHz USB output
• Two copies of 14.31818-MHz reference clock
• Programmable to 133- or 100-MHz operation
• Power management control pins for clock stop and shut down
• Available in 56-pin SSOP
