W180 - Peak Reducing EMI Solution

General Description

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

Crystal Connection or External Reference Frequency Input: This pin has dual functions.

It may either be connected to an external crystal, or to an external reference clock.

Key Features

  • Cypress PREMIS™ family offering.
  • Generates an EMI optimized clocking signal at the output.
  • Selectable output frequency range.
  • Single 1.25% or 3.75% down or center spread output.
  • Integrated loop filter components.
  • Operates with a 3.3V or 5V supply.
  • Low power CMOS design.
  • Available in 8-pin SOIC (Small Outline Integrated Circuit) Table 1. Modulation Width Selection SS% 0 1 W180-01, 02, 03 Output Fin ≥ Fout ≥ Fin.
