APPLICATIONS INFORMATION
Circuit and Layout Recommendations
The recommended circuit configuration for 3-Channel CDS
mode operation is shown in Figure 15. The recommended input
coupling capacitor value is 0.1
F (see Circuit Operation section
for more details). A single ground plane is recommended for the
AD9814. A separate power supply may be used for DRVDD,
the digital driver supply, but this supply pin should still be
decoupled to the same ground plane as the rest of the AD9814.
The loading of the digital outputs should be minimized, either
by using short traces to the digital ASIC, or by using external
digital buffers. To minimize the effect of digital transients during
major output code transitions, the falling edge of CDSCLK2
should occur coincident with or before the rising edge of
ADCCLK (see Figures 1 through 4 for timing). All 0.1
F
decoupling capacitors should be located as close as possible to
the AD9814 pins. When operating in single channel mode, the
unused analog inputs should be grounded.
Figure 16 shows the recommended circuit configuration for 3-
Channel SHA mode. All of the above considerations also apply
for this configuration, except that the analog input signals are
directly connected to the AD9814 without the use of coupling
capacitors. The analog input signals must already be dc-biased
between 0 V and 4 V (see the Circuit Operation section for
more details).
