Embedded Intel x86 Clocks

SL28EB742 Embedded Intel x86 Block Diagram

Silicon Labs' embedded Intel x86 clock generators support a wide variety of chipsets and processors. They provide all the necessary clock generation for the CPU, memory controller (chipset north bridge), I/O controller (chipset south bridge) as well as exceed the latest timing requirements for industry standards such as PCI Express, SATA, USB, LAN, and legacy PCI.

The CY28xxx, SL28xxx and SL28EBxxx devices are designed for industrial PC (IPC) and storage applications like DVR/NVR, NAS and enterprise storage. They are also ideal for switch routers, WAN and multi-function products. Specialized programmable features such as over-clocking, under-clocking, programmable spread spectrum bandwidth and modulation rates, as well as slew rate control help with signal integrity and EMI reduction. Industrial grade operation and industry-standard footprints for drop-in replacements offer system designers the flexibility and performance needed for industrial applications.

The low power consumption of the SL28610, SL28748 and SL28EB717 devices makes them ideal for mobile applications and small form factor embedded modules, as well as digital signage, home networking, industrial controls, medical and test equipment.

Selecting the Optimum PCIe Clock Source

To ensure proper compliance with the PCIe standard, systems require careful attention to the timing subsystem and architecture. This article explores some of the standard clocking architectures for PCIe and considers their benefits for typical system applications, including: clock architecture selection (Common Refclk, Separate Refclk or Data Clocked Refclk), requirements in applications that use FPGAs, jitter performance of the reference clock, use of spread spectrum clocking, and more.

SyncE and IEEE 1588: Sync Distribution for a Unified Network

Since Ethernet or packet based networks operate asynchronously, many of the traditional applications that depend on synchronization are not supported. Designers increasingly need to combine services supplied by data efficient packet networks with the ones served by the large installed base of traditional SONET/SDH networks. Both Synchronous Ethernet (SyncE) and packet timing using the IEEE 1588 protocol offer viable solutions in unifying service delivery over both networks. Download this new app note from Silicon Labs to discover methods for transporting synchronization and potential synchronized timing implementations.

Prototyping with Frequency-Flexible Crystal Oscillators

Developers of new systems ideally should make decisions regarding clocking requirements early in the design process. Although clocking rates are critical parameters that should be known in advance, determining these rates sometimes requires experimentation and re-evaluation. The use of frequency-flexible, programmable crystal oscillators (XOs) as prototyping tools can facilitate the process of validating system performance and help streamline the overall product development cycle.
