SL28EBxxx Embedded Intel x86 Clock Generators

Silicon Labs offers a family of Intel-compliant x86 clocks for embedded computing, communications, and industrial applications.   These devices provide all necessary clock generation for the CPU, memory controller (chipset north bridge) and I/O controller (chipset south bridge). Clock generation is also provided for the latest timing industry standards, including SATA, USB, LAN, PCI Express, and legacy PCI. Also available as Intel-compliant PCIe clock buffers/zero-delay buffers.

Features

  • Clock Generators for legacy Intel processors
  • Multi-PLL architecture for flexible, independent clocking
  • Low power push-pull differential buffers for PCIe
  • Integrated voltage regulator and damping resistors on differential clocks
  • Integrated LAN clock for cost/component savings
  • Integrated IEEE1394 clock for cost/space component savings
  • 8-step programmable slew rate control for rise time and fall time control
  • Industry-best spread spectrum technology for optimum system EMI reduction
