CIRCUIT LAYOUT INFORMATION
The AD9991 typical circuit connection is shown in Figure 38.
The PCB layout is critical in achieving good image quality from
the AD999x products. All of the supply pins, particularly the
AVDD1, TCVDD, RGVDD, and HVDD supplies, must be
decoupled to ground with good quality high frequency chip ca-
pacitors. The decoupling capacitors should be located as close
as possible to the supply pins, and should have a very low im-
pedance path to a continuous ground plane. There should also
be a 4.7 μF or larger value bypass capacitor for each main sup-
ply—AVDD, RGVDD, HVDD, and DRVDD—although this
is not necessary for each individual pin. In most applications,
it is easier to share the supply for RGVDD and HVDD, which
may be done as long as the individual supply pins are separately
bypassed. A separate 3 V supply may also be used for DRVDD,
but this supply pin should still be decoupled to the same ground
plane as the rest of the chip. A separate ground for DRVSS is not
recommended. It is recommended that the exposed paddle on
the bottom of the package be soldered to a large pad, with mul-
tiple vias connecting the pad to the ground plane.
The analog bypass pins (REFT, REFB) should also be
carefully decoupled to ground as close as possible to their
respective pins. The analog input (CCDIN) capacitor
should also be located close to the pin.
The H1–4 and RG traces should be designed to have low
inductance to avoid excessive distortion of the signals. Heavier
traces are recommended because of the large transient current
demand on H1–4 by the CCD. If possible, physically locating the
AD9991 closer to the CCD will reduce the inductance on these
lines. As always, the routing path should be as direct as possible
from the AD9991 to the CCD.
The AD9991 also contains an on-chip oscillator for driving an
external crystal. Figure 39 shows an example application using
a typical 24 MHz crystal. For the exact values of the external
resistors and capacitors, it is best to consult with the crystal
manufacturer’s data sheet.
