The 844008I-01 is an 8 output LVDS Synthesizer optimized to generate GbE/10GbE reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from IDT. Using a 25MHz parallel resonant crystal, the following frequencies can be generated based on the F_SEL pin: 125MHz or 156.25MHz. The 844008I-01 uses IDT's 3rd generation low phase noise VCO technology and can achieve <1ps typical rms phase jitter, easily meeting GbE/10GbE jitter requirements. The 844008I-01 is packaged in a 32-pin TQFP or 32 VFQFN packages.

Features

  • Eight LVDS outputs
  • Crystal oscillator interface
  • Supports the following output frequencies: 125MHz or 156.25MHz
  • VCO: 625MHz
  • RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz - 20MHz): 0.38ps (typical)
  • Full 3.3V supply mode
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free (RoHS 6) packages
