W166 - Spread Spectrum Frequency Timing Generator

General Description

Output Modulated Frequency: Frequency modulated copy of the reference input (SSON# asserted).

External Reference Frequency Input: Clock input.

No Connect: This pin must be left unconnected.

Key Features

  • Maximized EMI suppression using Cypress’s Spread Spectrum technology.
  • Generates a spread spectrum copy of the provided input.
  • Selectable spreading characteristics.
  • Integrated loop filter components.
  • Operates with a 3.3V or 5V supply.
  • SSON# pin enables frequency spreading.
  • Low power CMOS design.
  • Available in 8-pin SOIC (Small Outline Integrated Circuit) is greatly reduced. Use of this technology allows systems to pass increa.

W166 Spread Spectrum Frequency Timing Generator Features • Maximized EMI suppression using Cypress’s Spread Spectrum technology • Generates a spread spectrum copy of the provided input • Selectable spreading characteristics • Integrated loop filter components • Operates with a 3.3V or 5V supply • SSON# pin enables frequency spreading • Low power CMOS design • Available in 8-pin SOIC (Small Outline Integrated Circuit) is greatly reduced. Use of this technology allows systems to pass increasingly difficult EMI testing without resorting to costly shielding or redesign. In a system, not only is EMI reduced in the various clock lines, but also in all signals which are synchronized to the clock.
