Cypress CY25811/12/14 Spread Spectrum Clock Generator Datasheet
The CY25811, CY25812 and CY25814 are spread‑spectrum clock generator (SSCG) ICs that reduce EMI by modulating the clock frequency. They accept clock, crystal or resonator inputs and provide 1×, 2× or 4× multiplication with center‑spread or down‑spread modulation.
Available in 8‑pin SOIC and 8‑pin TSSOP packages, the devices operate over commercial (0 °C‑70 °C) and industrial (‑40 °C‑85 °C) temperature ranges and feature low power dissipation (≈52 mW at 6 MHz).
