AN49107 - Total System Timing and EMI Reduction Using the CY25400 Spread Spectrum Clock Generator

Several applications require a number of independent frequencies to be generated using clock generators. Crystals and clock generators with one or two PLLs limit this requirement. Moreover traditional methods (ferrite beads, filtering, and so on.) are followed for EMI reduction with compromise in design time and accuracy. These limitations and issues are overcome by using Cypress CY254XX and CY254X series.
