2.2.1 Evaluation Setup Requirement

At a minimum, evaluation of the buffer mode requires:

  • A DC power supply capable of at least 3.0V, 2A
  • A high-quality signal source, such as an SMA100B
  • A spectrum analyzer or phase noise analyzer
  • A PC running Windows 7 or a more recent version with TICS Pro software installed

Full evaluation requires the following additional hardware:

  • A high-speed 4-CH oscilloscope capable of resolving 5ps step size for SYSREF delay tuning
  • A 2-CH arbitrary function generator or other pulse source capable of outputting complementary LVDS pulses and DC levels (1.25V ± 0.2V, differential, into 100Ω DC load) for triggering SYSREF, SYNCing the dividers, and determining SYSREF windowing values
