AD9981
Adding a series resistor of value 50 to 200 can suppress
reflections, reduce EMI, and reduce the current spikes inside of
the AD9981. If series resistors are used, place them as close to
the AD9981 pins as possible, (although try not to add vias or
extra length to the output trace to get the resistors closer).

If possible, limit the capacitance that each digital output drives
to less than 10 pF. This is easily accomplished by keeping traces
short and by connecting the outputs to only one device. Loading
the outputs with excessive capacitance increases the current
transients inside of the AD9981 and creates more digital noise
on its power supplies.
Digital Inputs
Digital inputs on the AD9981 (HSYNC0, HSYNC1, VSYNC0,
VSYNC1, SOGIN0, SOGIN1, SDA, SCL and CLAMP) were
designed to work with 3.3 V signals, but are tolerant of 5.0 V
signals. Therefore, no extra components need to be added if
using 5.0 V logic.
Any noise that gets onto the Hsync input trace adds jitter to the
system. Therefore, minimize the trace length and do not run
any digital or other high frequency traces near it.
REFERENCE Bypass
The AD9981 has three reference voltages that must be bypassed
for proper operation of the input PGA. REFLO and REFHI are
connected to each other through a 10 μF capacitor. REFCM is
connected to ground through a 10 μF capacitor. These refer-
ences are used by the input PGA circuitry to assure the greatest
stability. Place them as close to the AD9981 pin as possible.
Make the ground connection as short as possible.
