Test Conditions/Comments
Differential input
High frequency distribution (VCO divider)
Distribution only (VCO divider bypassed)
Measured at 2.4 GHz; jitter performance is improved
with slew rates > 1 V/ns
Larger voltage swings may turn on the protection
diodes and may 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
Self-biased

Test Conditions/Comments
Termination = 50 Ω to VS − 2 V
Differential (OUT, OUT)
Using direct to output; see Figure 25 for peak-to –
peak differential amplitude
VOH − VOL for each leg of a differential pair for
default amplitude setting with driver not
toggling; see Figure 25 for variation over
frequency
Differential termination 100 Ω at 3.5 mA
Differential (OUT, OUT)
The AD9516 outputs toggle at higher
frequencies, but the output amplitude may not
meet the VOD specification; see Figure 26
VOH − VOL measurement across a differential pair
at the default amplitude setting with output
driver not toggling; see Figure 26 for variation
over frequency
This is the absolute value of the difference
between VOD when the normal output is high vs.
when the complementary output is high
(VOH + VOL)/2 across a differential pair
This is the absolute value of the difference
between VOS when the normal output is high vs.
when the complementary output is high
Output shorted to GND
Single-ended; termination = 10 pF
