The Cypress CY28325OC-3 is a Spread Spectrum Clock Generator designed to reduce electromagnetic interference (EMI) in electronic systems. It integrates a PLL and accepts LVTTL or crystal inputs, delivering a spread-spectrum clock output at frequencies up to 1MHz. Packaged in a 48-BSSOP, this device is ideal for consumer electronics, PCs, and industrial applications where EMI compliance is critical.

  • Spread Spectrum Technology: Reduces EMI emissions, simplifying compliance with regulatory standards.
  • Flexible Input Options: Accepts LVTTL or crystal, providing design flexibility for various clock sources.
  • Integrated PLL: Ensures stable frequency generation with minimal external components.
  • Compact Package: 48-BSSOP saves board space in space-constrained designs.
