Power Supply
V
D
Main Power Supply
These pins supply power to the main ele-
ments of the circuit. It should be as quiet and
filtered as possible.
Digital Output Power Supply
A large number of output pins (up to 52)
switching at high speed (up to 140 MHz)
generates a lot of power supply transients
(noise). These supply pins are identified
separately from the V
D
pins so special care
can be taken to minimize output noise trans-
ferred into the sensitive analog circuitry.
If the AD9886 is interfacing with lower-
voltage logic, V
DD
may be connected to a
lower supply voltage (as low as 2.5 V) for
compatibility.
Clock Generator Power Supply
The most sensitive portion of the AD9886 is
the clock generation circuitry. These pins
provide power to the clock PLL and help the
user design for optimal performance. The
designer should provide “quiet,” noise-free
power to these pins.
Ground
The ground return for all circuitry on chip.
It is recommended that the AD9886 be
assembled on a single solid ground plane,
with careful attention to ground current paths.

Data Input for SCAN Function
Data can be loaded serially into the 48-bit
SCAN register through this pin, clocking it in
with the SCAN
CLK
pin. It then comes out of
the 48 data outputs in parallel. This function
is useful for loading known data into a graph-
ics controller chip for testing purposes.
Data Output for SCAN Function
The data in the 48-bit SCAN register can be
read through this pin. Data is read on a FIFO
basis and is clocked via the SCAN
CLK
pin.
Data Clock for SCAN Function
This pin clocks the data through the SCAN
register. It controls both data input and
data output.
