DC1884 is easy to set up to evaluate the performance of
the LTM9011 family of A/D converters. For proper mea-
surement equipment setup, refer to Figure 1 and follow
the procedure explained in the following sections.

QUICK START PROCEDURE
Setup
If a DC1371 data acquisition and collection system was
supplied with the DC1884, follow the DC1371 Quick Start
Guide to install the required software and to connect the
DC1371 to the DC1884 and to a PC.
DC1884 Board Jumpers
The DC1884 board should have the following jumper set-
tings as default positions (as per Figure 1):
JP14: PAR/SER: Selects Parallel or Serial Programming
Mode. (Default: Serial)
Optional Jumpers AJ3 and J6: Term: Enables/Disable
Optional Output Termination. (Default: Removed)
JP5: ILVDS:Selects Either 1.75mA or 3.5mA of Output
Current for the LVDS Drivers. (Default: Removed)
JP1 and JP2: Lane: Selects Either1-Laneor2-LaneOutput
Modes (Default: Removed)
Note: The DC1371 does not support 1-Lane operation.
JP9: SHDN: Enables and Disables the LTM9011.
(Default: Removed)
JP8: WP: Enable/Disables Write Protect for the EEPROM.
(Default: Removed)
Note: Optional jumper should be left open to ensure proper
serial configuration.
Applying Power and Signals to the DC1884
The DC1371 is used to acquire data from the DC1884. The
DC1371 must first be connected to a powered USB port
and have 5V applied power before applying 3.5V across
the pins marked V+and “GND” on the DC1884. DC1884
requires 3.5V for proper operation.
The DC1884 demonstration circuit requires up to 700mA
depending on the sampling rate and the A/D converter
supplied.
The DC1884 should not be removed or connected to the
DC1371 while power is applied.
Analog Input Network
For optimal distortion and noise performance, the RC
network on the analog inputs may need to be optimized
for different analog input frequencies. For input frequen-
cies above 70MHz, refer to the LTM9011 data sheet for a
proper input network.
In almost all cases, filters will be required on both analog
input and encode clock to provide data sheet SNR.
The filters should be located close to the inputs to avoid
reflections from impedance discontinuities at the driven
end of a long transmission line. Most filters do not present
50Ω outside the passband. In some cases, 3dB to 10dB
pads may be required to obtain low distortion.
If your generator cannot deliver full-scale signals without
distortion,youmaybenefitfromamediumpoweramplifier
based on a gallium arsenide gain block prior to the final
filter. This is particularly true at higher frequencies where
IC based operational amplifiers may be unable to deliver
the combination of low noise figure and high IP3 point
required. A high order filter can be used prior to this final
amplifier, and a relatively lower Q filter used between the
amplifier and the demonstration circuit.

QUICK START PROCEDURE
Encode Clock
Note: Apply an encode clock to the SMA connector on
the DC1884 demonstration circuit board marked “J2
CLK+.” As a default, the DC1884 is populated to have a
single-ended input.
For the best noise performance, the ENCODE input must
be driven with a very low jitter, square wave source. The
amplitude should be large, up to 3VP-P or 13dBm. When
using a sinusoidal signal generator, a squaring circuit can
be used. Linear Technology also provides demo board
DC1075A that divides a high frequency sine wave by four,
producing a low jitter square wave for best results with
the LTM9011.
Usingbandpassfilters on theclockand the analog input will
improve the noise performance by reducing the wideband
noise power of the signals. In the case of the DC1884 a
bandpass filter used for the clock should be used prior
to the DC1075A. Data sheet FFT plots are taken with 10
pole LC filters made by TTE (Los Angeles, CA) to suppress
signal generator harmonics, non harmonically related
spurs and broadband noise. Low phase noise Agilent
8644B generators are used for both the clock input and
the analog input.
Digital Outputs
Data outputs, data clock, and frame clock signals are
available on J1 of the DC1884. This connector follows the
VITA-57/FMC standard, but all signals should be verified
when using an FMC carrier card other than the DC1371.
Software
The DC1371 is controlled by the PScope system software
that can bedownloaded fromthe Linear Technology website
at http://www.linear.com/software/.
To startthe data collectionsoftware, “PScope.exe,” whichis
installed by default to \Program Files\LTC\PScope\, double
click the PScope icon or bring up the run window under
the start menu, and browse to the PScope directory and
select “PScope.”
If the DC1884 isproperly connected tothe DC1371, PScope
should automatically detect the DC1884 and configure
itself accordingly.
If everything is hooked up properly and a powered and
suitable convert clock is present, clicking the “Collect”
button should result in time and frequency plots displayed
in the PScope window. Additional information and help for
PScope is available in the DC1371 Quick Start Guide, and
in the online help feature within the PScope program itself.

Serial Programming
PScope has the ability to program the DC1884 serially
through the DC1371. There are several options available
in the LTM9011 family that are only available through
serially programming. PScope allows all of these features
to be tested.
These options are available by first clicking on the “Set
Demo Bd Options” icon on the PScope toolbar (Figure 2).
This will bring up the menu shown in Figure 3.
This menu allows any of the options available for the
LTM9011 family to be programmed serially. The LTM9011
family has the following options:
Randomizer: Enables Data Output Randomizer.
• Off (Default): Disables data output randomizer.
• On: Enables data output randomizer.
