1.0 Introduction
This Evaluation Board may be used to evaluate the ADC10DV200, or ADC11DV200. The ADC is one of a family of 10 and 11 bit converters that provides data at rates of up to 200MHz. Further reference in this manual to the ADC10DV200 is meant to also include the other
frequency domain plot, shows dynamic performance in the form of SNR, SINAD, THD and SFDR. The latest WaveVision hardware and software is available through the National Semiconductor website:
http://www.national.com/store/view_item/index.html?nsid= WAVEVSN+BRD+5.1
listed parts unless otherwise specified The evaluation board is designed to be used with the
WaveVision5™ Data Capture Board which is connected to a personal computer through a USB port and running WaveVision5™ software, operating under Microsoft Windows. The software can perform an FFT on the captured data upon command and, in addition to a

3.0 Quick Start
Refer to Figure 1 for locations of jumpers, test points and major components. Refer to Figure 2 for the test set up. The board is configured by default to use a external clock source and internal reference. Refer to Section 4.0 and the Appendix for more information on jumper settings. The input network of this board is configured for input frequencies greater than 70MHz. Refer to Section 4.1 for more information about input networks.
You must have version 5.0 or later of the WaveVision™ software to properly test this board. You can download the latest version from:
http://www.national.com/analog/adc/wavevision5
1. Apply power to the WaveVision5™ board and connect it to the computer using a USB cable. See the WaveVision5™ Board Manual for operation of that board. Connect the evaluation board to the WaveVision™ Digital Interface Board.
2. Connect a clean +5V power supply to pin 2 of Power Connector JR507. Pin 1 is ground.
3. Connect a signal from a 50-Ohm source to connector J301 or J302. Be sure to use a bandpass filter before the Evaluation Board.
4. Adjust the input signal amplitude as needed to ensure that the signal does not over-range by examinining a histogram of the output data with the WaveVision5™ software.
4.0 Functional Description
The ADC10DV200 Evaluation Board schematic is shown in Section 6. A list of test points and jumper settings can be found in the Appendix.
4.1 Analog Input
To obtain the best distortion results the analog input network must be optimized for the signal frequency being applied. The ADC10DV200 Evaluation Board comes configured as seen in Figure 3.
Figure 3. Analog Input Network for FIN > 70MHz
The input network is intended to accept a low-noise sine wave and will perform well over a wide input frequency range. To accurately evaluate the dynamic performance of this converter, the input test signal will have to be passed through a high-quality bandpass filter.

Page 5
Input signals can also be amplified using an onboard LMH6517 DVGA (U601). To use the DVGA, some components must be installed and some removed. The following components must be installed: R651-R656. The following components must be removed: R302, R303, R309, and R310. Then connect signals from a 50-Ohm source to connectors J601 and J607.
4.2 ADC reference circuitry
The ADC10DV200 can use an internal or external voltage reference. The internal reference is selectable between a
0.75V or 0.5V reference. External references can be set
from 0.2V to 1.4V. This Evaluation Board is configured to use the internal 0.75V reference.
4.3 ADC clock circuit
Components can be installed or removed to select the path of the clock to the ADC. While not as convenient as pin-type jumpers, these introduce less distortion into the clock signal.
Care must be taken to provide a high quality low jitter clock source. A single ended input clock can be buffered by U203 (NC7SV125) and applied to the ADC’s clock input pin. Or U203 can be bypassed and the input clock pin driven directly.
A differential clock can also be applied to the ADC’s clock input pins through U201 (ETC-1-13).
Refer to Appendix A to configure the clock for your application. The Evaluation Board is configured by default to use a single ended clock to drive the input pins directly.
should be connected to the Signal Input SMA connectors J301 or J302. When evaluating dynamic performance, an appropriate signal generator (such as the HP8644B or the R&S SME-03) with 50 Ohm source impedance should be connected to the Analog Input connector through an appropriate bandpass filter as even the best signal generator available can not produce a signal pure enough to evaluate the dynamic performance of an ADC.
If this board is used in conjunction with the WaveVision5™ Data Capture Board and WaveVision5™ software, a USB must be connected between the Data Capture Board Board and the host. See the WaveVision5™ Data Capture Board manual for details.
4.4 Digital Data Output
The LVDS digital output data is available for probing at test points TP601 through TP624. The signals are also available at the WaveVision™ (WV5) connector J602.
4.5 Data Format/ Duty Cycle Stabilizer
Output data format and the duty cycle stabilizer (DCS) are controlled by jumper J401. Shorting pins 1-2 of J401 sets the output format to offset binary with DCS On. This is the default setting. Shorting pins 3-4 of J401 sets the output format to 2’s complement with DCS Off. Shorting pins 5-6 of J401 sets the output format to offset binary with DCS Off. Shorting pins 7-8 of J401 sets the output format to 2’s complement with DCS On.
4.6 Power Supply Connections
Power to this board is supplied through power connector J507. The only supply needed is +5V at pin 2 plus ground at pin 1.
Voltage and current requirements for the ADC10DV200 Evaluation Board are:
+5.0V at 500 mA
5.0 Installing the ADC10DV200 Evaluation Board
The evaluation board requires power supplies as described in Section 4.6. An appropriate signal source

A1.0 Operating in the Computer Mode
The ADC10DV200 Evaluation Board is compatible with the WaveVision5™ Data Capture Board and WaveVision5™ software. You can download the latest version from: http://www.national.com/analog/adc/wavevision5
When connected to the WaveVision5™ Board, data capture is easily controlled from a personal computer operating in the Windows environment. The data samples that are captured can be observed on the PC video monitor in the time and frequency domains. The FFT analysis of the captured data yields insight into system noise and distortion sources and estimates of ADC dynamic performance such as SINAD, SNR and THD.
