Device Overview

Summary

The ZL30281 is a high-performance PCIe Gen 1-4 clock generator.  From a 25MHz crystal or CMOS input these devices generate 100 MHZ in four pre-programmed output configurations immediately on power-up. The
devices have industry-leading output jitter of 160fs RMS (12kHz to 20MHz).


Additional Features
  • 25MHz crystal or CMOS input
  • Generates PCIe 1, 2, 3, 4 compliant clocks
  • Four default configurations selected by hardware pins at reset:
    • Config0: 100MHz on output OC1 (CML format)
    • Config1: 100MHz on OC1, OC2 (CML)
    • Config2: 100MHz on OC1 (CML), OC2 (HSTL)
    • Config3: 100MHz on OC1, OC2 (CML) and 25MHz LVCMOS on OC3
  • Per-output controls (using SPI or I2C interface)
  • Per-output enable/disable and glitch-less start/stop (stop high or low)
  • Precise output alignment circuitry and per-output phase adjustment
  • SPI or I2C processor Interface
  • Tiny 5x5mm QFN package
