AD10677
ANALOG AND DIGITAL GROUNDING
While the AD10677 provides separate analog and digital ground
pins, the device should be treated as an analog component. Proper
grounding is essential in high speed, high resolution systems.
Multilayer printed circuit boards are recommended to provide
optimal grounding and power distribution. The use of power and
ground planes provides distinct advantages. Power and ground
planes minimize the loop area encompassed by a signal and its
return path, minimize the impedance associated with power and
ground paths, and provide a distributed capacitor formed by the
power plane, printed circuit board material, and ground plane.
The AD10677 unit has four metal standoffs (see Figure 6). MH2
is located in the center of the unit and MH1 is located directly
below analog header P3. Both of these standoffs are tied to analog
ground and should be connected accordingly on the next level
assembly for best performance. The two standoffs located near
P1 and P2 (MH3 and MH4) are tied to digital ground and should
be connected accordingly on the next level assembly.
Other Notes
The circuit is configured on a 2.2" × 2.8" laminate board with
three sets of connector interface pads. The pads are configured
in such a way that easy keying is provided to the user. The pads
are made for low profile applications and have a total height of
0.12" after mating. The part numbers for the header mates are
provided in Figure 6. All pins of the analog and digital sections
are described in Table 7 and Table 8.

Evaluation Board
The AD10677 evaluation board provides an easy way to test the
16-bit 65 MSPS A/D converter. The board requires a clock
source, an analog input signal, two 3.3 V power supplies, and a
5 V power supply. The clock source is buffered on the board to
provide the clock for the AD10677, a latch, and a data ready
signal. The ADC digital outputs are latched on-board by a
74LCX16374. The digital outputs and output clock are available
on a 40-pin connector J1. Power is supplied to the board via
uninsulated metal banana jacks.
The analog input is connected via an SMA connector, AIN. The
analog input section provides for a single-ended input option or
a differential input option. The board is shipped in a single-
ended analog input option. Removing a ground tie at E17
converts the circuit to a differential analog input configuration.
