W183 - Full Feature Peak Reducing EMI Solution

Datasheet Summary

Description

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

Non-Modulated Output: This pin provides a copy of the reference frequency.

This output will not have the Spread Spectrum feature regardless of the state of logic input SSON#.

Features

  • Cypress PREMIS™ family offering.
  • Generates an EMI optimized clocking signal at the output.
  • Selectable output frequency range.
  • Single 1.25%, 3.75% down or center spread output.
  • Integrated loop filter components.
  • Operates with a 3.3 or 5V supply.
  • Low power CMOS design.
  • Available in 14-pin SOIC (Small Outline Integrated Circuit) Table 1. Modulation Width Selection SS% 0 1 W183 Output Fin ≥ Fout ≥ Fin.
  • 1.25% Fin ≥ Fout.
