FS784 - Low EMI Spectrum Spread Clock

Download the FS784 datasheet PDF. This datasheet also covers the FS781 variant, as both devices belong to the same low emi spectrum spread clock family and are provided as variant models within a single manufacturer datasheet.

Description

The Cypress FS781/82/84 are Spread Spectrum clock generator ICs (SSCG) designed for the purpose of reducing electromagnetic interference (EMI) found in today’s high-speed digital systems.

Features

  • Spread Spectrum clock generator (SSCG) with 1×, 2×, and 4× outputs.
  • 6- to 82-MHz operating frequency range.
  • Modulates external clocks including crystals, crystal oscillators, or ceramic resonators.
  • Programmable modulation with simple R-C external loop filter (LF).
  • Center spread modulation.
  • 3V-5V power supply.
  • TTL-/CMOS-compatible outputs.
  • Low short-term jitter.
  • Low-power Dissipation.
  • 3.3 VDC = 37 mW.
