GHz
High frequency distribution (VCO divider)
1.6

mV p-p
Measured at 2.4 GHz; jitter performance is improved
with slew rates > 1 V/ns
Input Level, Differential

Larger voltage swings may turn on the protection
diodes and may degrade jitter performance

980
mV
This is VOH VOL for each leg of a differential pair for
default amplitude setting with driver not toggling; the
peak-to-peak amplitude measured using a differential
probe across the differential pair with the driver
toggling is roughly 2× these values (see Figure 25 for
variation over frequency)
LVDS CLOCK OUTPUTS
Differential termination 100 at 3.5 mA
OUT4, OUT5, OUT6, OUT7
Differential (OUT, OUT)
Output Frequency
800
MHz
The AD9517 outputs toggle at higher frequencies, but
the output amplitude may not meet the VOD
specification; see Figure 26
Output Differential Voltage (VOD)
247
360
454
mV
VOH VOL measurement across a differential pair at the
default amplitude setting with output driver not
toggling; see Figure 26 for variation over frequency
Delta VOD
25
mV
This is the absolute value of the difference between
VOD when the normal output is high vs. when the
complementary output is high
Output Offset Voltage (VOS)
1.125
1.24
1.375
V
(VOH + VOL)/2 across a differential pair
Delta VOS
25
mV
This is the absolute value of the difference between
VOS when the normal output is high vs. when the
complementary output is high
Short-Circuit Current (ISA, ISB)
