SKYWORKS SI5350A-B12026-GT

The Si5350A is a highly-flexible, user-definable custom clock generator that is ideally suited for replacing crystals and crystal oscillators in cost-sensitive applications. Based on a PLL + high resolution fractional divider MultiSynthTM architecture, the Si5350A can generate any frequency up to 200 MHz on each of its outputs with 0 ppm error. Spread spectrum is selectable (on/off) on any of the outputs. Custom Si5350A configurations can be created using ClockBuilder Pro.

• Generates up to 8 non-integer-related frequencies from 2.5 kHz to 200 MHz
• Exact frequency synthesis at each output (0 ppm error)
• Glitchless frequency changes
• Low output period jitter: <70 ps pp, typ
• Configurable Spread Spectrum, selectable at each output
• User-configurable control pins:
  • Output Enable (OEB_0/1/2)
  • Power Down (PDN)
  • Frequency Select (FS_0/1)
  • Spread Spectrum Enable (SSEN)
• Supports static phase offset
• Rise/fall time control
• Operates from a low-cost, fixed frequency crystal: 25 or 27 MHz
