The CY2547QI is an 8-output, low-voltage programmable spread spectrum clock generator with four on-chip PLLs, supporting output frequencies from 3 to 166 MHz and input frequencies from 8 to 166 MHz. Operating at 1.8 V with an industrial temperature range of -40 to 85°C, it features I2C programmability, CMOS outputs, spread spectrum EMI reduction, and glitch-free frequency switching. Housed in a 24-pin QFN package, it is RoHS compliant.

Features

  • Four programmable PLLs
  • I2C serial programming
  • Input: crystal 8–48 MHz, clock 8–166 MHz
  • Output: 3–166 MHz (CY2545), 3–50 MHz
  • Programmable spread spectrum
  • Lexmark/Linear modulation profiles
  • Eight clock outputs, independent source
  • Glitch-free frequency switching
  • Programmable output drive strength
  • Cycle-to-cycle jitter max 150 ps
  • PLL lock time max 3 ms
  • Nonvolatile configuration memory

Benefits

  • Generates up to four independent clocks
  • Easy system integration via I2C
  • Flexible input/output frequency options
  • EMI reduction with spread spectrum
  • Customizable modulation for EMI needs
  • Supports complex multi-clock designs
  • No glitches during frequency changes
  • Output drive tailored to system needs
  • Stable clocks with low jitter
  • Fast PLL lock for quick startup
  • Retains settings after power cycle
  • Simplifies system clock architecture
