Test Conditions/Comments
Differential input
High frequency distribution (VCO divider)
Distribution only (VCO divider bypassed); this is the
frequency range supported by the channel divider
Measured at 2.4 GHz; jitter performance is improved with
slew rates > 1 V/ns
Larger voltage swings can turn on the protection diodes
and can degrade jitter performance
Self-biased; enables ac coupling
With 200 mV p-p signal applied; dc-coupled
CLK ac-coupled; CLK ac-bypassed to RF ground

Test Conditions/Comments
Termination = 50 Ω to VS_DRV − 2 V
Differential (OUT, OUT)
Using direct to output; see Figure 21 (higher
frequencies are possible, but amplitude will
not meet the V
output frequency is limited by either the
maximum VCO frequency or the frequency at
the CLK inputs, depending on the AD9520
configuration
Single-ended; termination = 10 pF
