The CY2545QIT is an 8-output, low-voltage programmable spread spectrum clock generator with four integrated PLLs, supporting output frequencies from 3.0 to 166.0 MHz and input frequencies from 8.0 to 166.0 MHz. It features I2C programmability, CMOS outputs, selectable I/O voltages (2.5/3.0/3.3 V), and operates from 2.25 to 3.6 V across -40 to 85°C. Halogen free and RoHS compliant, it is ideal for EMI reduction in industrial clocking applications.

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
