INPUT CHARACTERISTICS
Each pin has a 30 kΩ internal pull-up resistor

The minus sign indicates that current is flowing out of
the AD9520, which is due to the internal pull-up resistor

Test Conditions/Comments
SP1, SP0
These pins do not have internal pull-up/pull-down
resistors
Logic Level 0

VS is the voltage on the VS pin
Logic Level
0.4 × VS
0.65 × VS

These pins can be floated to obtain Logic Level ; if
floating the pin, connect a capacitor to ground

OUTPUT CHARACTERISTICS
When selected as a digital output (CMOS); there are
other modes in which these pins are not CMOS digital
outputs; see Table 48, Register 0x017, Register 0x01A,
and Register 0x01B
Output Voltage High, VOH

MAXIMUM TOGGLE RATE
100
MHz
Applies when mux is set to any divider or counter
output or PFD up/down pulse; also applies in analog
lock detect mode; usually debug mode only; beware that
spurs can couple to output when any pin is toggling
ANALOG LOCK DETECT
Capacitance
3
pF
On-chip capacitance; used to calculate RC time
constant for analog lock detect readback; use a pull-up
resistor
REF1, REF2, AND CLK FREQUENCY
STATUS MONITOR
Normal Range
