EVALUATION BOARD
Evaluation boards are offered to configure the AD9446 in either
CMOS or LVDS mode only. This design represents a recom-
mended configuration for using the device over a wide range of
sampling rates and analog input frequencies. These evaluation
boards provide all the support circuitry required to operate
the ADC in its various modes and configurations. Complete
schematics are shown in Figure 61 through Figure 64. Gerber
files are available from engineering applications demonstrating
the proper routing and grounding techniques that should be
applied at the system level.
It is critical that signal sources with very low phase noise
(<60 fsec rms jitter) be used to realize the ultimate performance
of the converter. Proper filtering of the input signal to remove
harmonics and lower the integrated noise at the input is also
necessary to achieve the specified noise performance.
The evaluation boards are shipped with a 115 V ac to 6 V dc
power supply. The evaluation boards include low dropout
regulators to generate the various dc supplies required by the
AD9446 and its support circuitry. Separate power supplies are
provided to isolate the DUT from the support circuitry. Each
input configuration can be selected by proper connection of
various jumpers (see Figure 61).

The LVDS mode evaluation boards include an LVDS-to-CMOS
translator, making them compatible with the high speed ADC
FIFO evaluation kit (HSC-ADC-EVALA-SC). The kit includes a
high speed data capture board that provides a hardware solution
for capturing up to 32 kB samples of high speed ADC output
data in a FIFO memory chip (user upgradeable to 256 kB
samples). Software is provided to enable the user to download
the captured data to a PC via the USB port. This software also
includes a behavioral model of the AD9446 and many other
high speed ADCs.
Behavioral modeling of the AD9446 is also available at
www.analog.com/ADIsimADC. The ADIsimADC™ software
supports virtual ADC evaluation using ADI proprietary behavioral
modeling technology. This allows rapid comparison between the
AD9446 and other high speed ADCs with or without hardware
evaluation boards.
The user can choose to remove the translator and terminations
to access the LVDS outputs directly.
