General Description

The SM802141 is a part of Micrel’s ClockWorks family of devices and provides an extremely low-noise timing solution for Ethernet clock signals.

The device operates from a 3.3V or 2.5V power supply and synthesizes differential LVPECL output clocks at 62.5MHz, 125MHz, 156.25MHz or 312.5MHz, selectable through logic control pins.

The SM802141 accepts a 25MHz crystal or LVCMOS reference clock.

Key Features

  • Configurable to generate up to four different LVPECL clock frequencies.
  • 2.5V or 3.3V operating range.
  • Typical phase jitter @ 125MHz (12kHz to 20MHz): 255 fsrms.
  • Industrial temperature range (.
  • 40C to +85C).
  • Green, RoHS, and PFOS compliant.
  • Available in 24-pin 4mm  4mm QFN package.
