W184 - Six Output Peak Reducing EMI Solution

Datasheet Summary

Description

Modulated Frequency Outputs: Frequency modulated copies 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.

Features

  • Cypress PREMIS™ family offering.
  • Generates an EMI optimized clocking signal at the output.
  • Selectable input to output frequency.
  • Six 1.25%, 3.75%, or 0% down or center spread outputs.
  • One non-Spread reference output.
  • Integrated loop filter components.
  • Operates with a 3.3 or 5V supply.
  • Low power CMOS design.
  • Available in 24-pin SSOP (Shrunk Small Outline Package).
  • Outputs may be selectively disabled Table 1.
