Large-Scale Data Center Clocking Guide

2025-07-16 11:02

With the rising demand for AI computation, cloud infrastructure, and distributed storage, large-scale data centers require extremely stable, low-jitter, and energy-efficient clock sources. The FCO differential crystal oscillator series—covering standard, ultra-low jitter (UJ), and power-saving (PG) types—offers complete voltage compatibility (1.8V–3.3V), logic options (LVPECL / LVDS / HCSL), and multiple compact packages (2520 to 7050). These oscillators are widely used in switching modules, synchronization control, NVMe servers, and edge systems.

Selection Tips & Matching Scenarios

  • Use UJ versions (FCO-7L-UJ / FCO-5L-UJ) for jitter-critical systems such as AI switches and synchronization units.
  • Space-constrained modules can benefit from compact models like FCO-3L-UJ or FCO-2L.
  • For power-sensitive edge or green platforms, the PG series (FCO-3L-PG / 5L-PG / 7L-PG) are ideal.
  • FCO-5L series offers wide voltage/output compatibility and is suited for general-purpose system timing.
