NOTICE - The following device(s) are recommended alternatives:

The IDT 650-14 is a low cost, low jitter, high performance clock synthesizer customized for networking systems applications. Using analog/digital Phase-Locked Loop (PLL) techniques, the device accepts a 25 MHz clock or fundamental mode crystal input to produce multiple output clocks of one fixed 25 MHz, a four (plus one) frequency selectable bank, and two frequency selectable clocks. All output clocks are frequency locked together. The IDT650-14 outputs have zero ppm synthesis error.

Features

  • Packaged in 20-pin SSOP
  • 25 MHz fundamental crystal or clock input
  • One fixed output clock of one 25 MHz
  • One bank of four frequency selectable output clocks
  • Three frequency selectable clock outputs
  • Zero ppm synthesis error on all clocks
  • Ideal for networking systems
  • Full CMOS output swing
  • Advanced, low power sub-micron CMOS process
  • Operating voltage of 3.3 V or 5.0 V
  • Industrial temperature range available
