Power Supply
The power supply must be a low-noise power supply, particularly when the devices on the board are being directly powered (onboard LDO regulators bypassed).
Phase Noise / Spectrum Analyzer
TI recommends that an Agilent E5052 Signal Source Analyzer or comparable test equipment is used to measure phase noise and RMS jitter.
Oscilloscope
To measure the output clocks AC performance, such as rise time or fall time, propagation delay, or skew, TI suggests using a real-time oscilloscope with 8+ GHz analog input bandwidth with 50-Ω inputs. To evaluate clock synchronization or phase alignment between multiple clock outputs, TI recommends using phase-matched, 50-Ω cables to minimize external sources of skew or other errors/distortion that may be introduced if using oscilloscope probes.
