Description
The W159H is an IC chip belonging to the electronic component model category. It is specifically designed to provide frequency sources that work with advanced multiprocessing Intel® architecture platforms. It supports a split voltage supply signaling providing 2.5V and 3.3V clock frequencies up to 133 MHz. The W159H uses a low-cost 14.31818-MHz reference crystal oscillator to generate 2.5V clock outputs that support CPUs, core logic chipsets, Direct RDRAM clock generators, and other components. It also supports 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.
Specifications and 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 package
Application Scenarios
The W159H IC chip is suitable for use in advanced multiprocessing Intel® architecture platforms that require a reliable source of frequency signals. It is ideal for use in CPUs, core logic chipsets, Direct RDRAM clock generators, and other components.
Comparison
