DESCRIPTION
Demonstration circuit 996 supports a family of 16-/14-bit
80Msps to 130Msps ADCs. Each assembly features one of
the following devices: LTC®2208, LTC2208-14, LTC2217,
LTC2216, LTC2215 high speed, high dynamic range ADCs.
This demonstration circuit only supports LVDS operation.
For demonstration of CMOS output signaling, please see
DC854.
Other members of this family include the LTC2207, a
105Msps 16-bit CMOS-only version of this device, as
well as lower speed versions and single-ended clock versions. These 7mm × 7mm QFN devices are supported by
Demonstration Circuits 918 and 919 (for single-ended
clock input).
Several versions of the 996 demo board supporting the
LTC2208 16-bit, LTC2217 16-bit and LTC2208-14 14-bit
series of A/D converters are listed in Table 1. Depending on
the required resolution, sample rate and input frequency,
the DC996 is supplied with the appropriate ADC and with
an optimized input circuit. The circuitry on the analog inputs
is optimized for analog input frequencies below 70MHz
or from 70MHz to 140MHz. For higher input frequencies,
contact the factory for support.

QUICK START PROCEDURE
Demonstration circuit 996 is easy to set up to evaluate
the performance of the LTC2208/LTC2208-14/LTC2217
A/D converters. Refer to Figure 1 for proper measurement
equipment setup and follow this procedure:
Setup
If a DC890 QuikEval™ II Data Acquisition and Collection
System was supplied with the DC996 demonstration
circuit, follow the DC890 Quick Start Guide to install the
required software and for connecting the DC890 to the
DC996 and to a PC.
DC996 Demonstration Circuit Board Jumpers
The DC996 demonstration circuit board should have the
following jumper settings as default: (as per Figure 1).
Figure 1 shows DC996A, the DC996B is shown in Figure 7.
J2: Mode (VCC) 2's Complement CDS Off
J3: SHDN: (Run) Dither (Off)
Applying Power and Signals to the DC996
Demonstration Circuit
Apply 3.3V across the pins marked “+3.3V” and “PWR
GND” on the DC996. The DC996 demonstration circuit
requires up to 700mA depending on the sampling rate and
the A/D converter supplied. If a DC890 is used to acquire
data from the DC996, the DC890 must be provided with
an external 6V ±0.5V 1A supply on turrets G7(+) and
G1(–) or the adjacent 2.1mm power jack to support the
power requirements of the Xilinx Spartan 3 FPGA active
terminations used to terminate the LVDS repeaters on the
DC996. The DC890 will not activate the LVDS mode unless
the DC890 detects external power present.
If external power is not present the DC890 will not configure the FPGA for LVDS terminations as this would result
in exceeding the USB 500mA limit. The DC890 contains
an onboard electronic circuit breaker which will shut off
the DC890 if external power is removed while the FPGA
is configured for LVDS active terminations.

with 50Ω. Apply an encode clock to the SMA connector

noise performance by reducing the wideband noise power
of the signals. 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 broad band noise. Low phase noise Agilent
8644B generators are used with TTE bandpass filters for
both the clock input and the analog input.
For the best noise performance, the ENCODE INPUT
must be driven with a very low jitter source. When using
a sinusoidal generator, the amplitude should often be as
large as possible, up to 3VP-P or 13dBm. Using bandpass
filters on the clock and the analog input will improve the
Apply the analog input signal of interest to the SMA connectors on the DC996 demonstration circuit board marked
“J5 ANALOG INPUT”. These inputs are capacitive coupled
to Balun transformers ETC1-1-13, or directly coupled
through flux-coupled transformers ETC1-1T.

DEMO MANUAL DC996
QUICK START PROCEDURE
An internally generated conversion clock output is available on J1 which could be collected via a logic analyzer, or
other data collection system if populated with a SAMTEC
MEC8-150 type connector or collected by the DC890 Data
Acquisition Board using the PScope™ System Software
provided or downloaded from the Linear Technology
website at http://www.linear.com/designtools/software/.
If a DC890 was provided, follow the DC890 Quick Start
Guide and the instructions below.
To start the data collection software if “PScope.exe”, is
installed (by default) in \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.
Analog Input Network
For optimal distortion and noise performance the RC
network on the analog inputs should be optimized for the
analog input frequencies of interest. At this point in time,
the circuit in Figure 3 for input frequencies below 70MHz.
For input frequencies from 70MHz to 140MHz, the circuit
in Figure 2 is used. These two input networks cover a
broad bandwidth and are not optimized for operation at a
specific input frequency.
For higher frequencies, a single balun (ETC1-1-13) is
populated on a DC996A board.
In almost all cases, filters will be required on both analog
input and encode clock to provide data sheet SNR.
If the DC996 demonstration circuit is properly connected to
the DC890, PScope should automatically detect the DC996,
and configure itself accordingly. If necessary the procedure
below explains how to manually configure PScope.
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.
Under the Configure menu, go to ADC Configuration.
Check the Config Manually box and use the following
configuration options:
The DC996A board has provision for a bandpass filter
prior to the balun. This may be populated if the board is
customized for a given frequency band. (Figure 5)
• 16-Bit (or 14-Bit if using LTC2208-14)
In some cases, 3dB to 10dB pads may be required to
obtain low distortion.
• Alignment: Left-16
• Bipolar (2’s complement)
• Positive clock edge
• Type: LVDS
If everything is hooked up properly, powered and a 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 DC890 Quick Start Guide and in
the online help available within the PScope program itself.
If your generator cannot deliver full-scale signals without
distortion, you may benefit from a medium power amplifier based on a Gallium Arsenide Gain block prior to the
final filter. This is particularly true at higher frequencies
where 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 demo circuit.
For advice on drive circuits or for input frequencies greater
than 220MHz, or for higher order bandpass filtering prior
to the ADC, contact the factory for support.

For input frequencies less than 5MHz, or greater than
150MHz, other input networks may be more appropriate.
Please consult the factory for suggestions on drivers
and networks if your signal sources extend outside these
ranges, or if you experience difficulties driving these suggested networks.
If this is populated as a BP filter, The reactance of L1 and
L3, and the series of C6 and C5 (and C21 and C23) should
be between 50Ω and 33Ω. The reactance of L2 should
match that of 1/2 C6^+C5.
The ratio of C5 to C6 will determine coupling be-tween the
two resonators, with a high ratio giving a narrow pass band.
As an example, for center frequency of 260MHz; –3dB
BW of 150MHz, C6, C23 = 27pF; C5, C21 = 68pF; L1, L3
= 18 nH; L2 = 7.5nH.
This has a flat passband over 80MHz. See Figure 6.
This filter is not intended as a band-defining filter, but
simply to minimize noise BW prior to the ADC, and to
minimize 2nd and 3rd originating in a drive amplifier. 2nd
harmonic of 260 is down at 1.
