EVALUATION BOARD DESCRIPTION

This data sheet describes the evaluation board for the AD7764/

AD7765 Σ-Δ ADCs. The AD7764/5 is a 24-bit ADC, serial data output with multiple decimation rate options incorporating a full band digital FIR filter. It combines wide input bandwidth with the benefits of Σ-Δ conversion with a performance of 102/104 dB SNR at 312ksps/156ksps respectively. The AD7764/AD7765 devices are ideal for applications like vibration monitoring, sonar, and general data acquisition where anti-alias protection is of importance.

Complete specifications for the AD7764/AD7765 devices are available in the AD7764/AD7765 data sheets available from Analog

Devices, Inc., and should be consulted in conjunction with this data sheet when using the evaluation board.

EVAL-AD7764/AD7765EDZ

board outputs the MCLK signal which the AD7764/5 use to sample the analog inputs.

The AD7764/AD7765 evaluation board interfaces directly with the FPGA located on the CED board via the SPORT header. The combination of the EVAL-CED1Z board allied with the EVAL-

AD7764/AD7765/EDZ software allows the user to upload samples taken by the AD7764/AD7765 device onto a PC showing the waveform being sampled, as well as allowing the data to be shown in histogram or FFT format. The EVAL-

AD7764/AD7765/4EDZ can also be used on a standalone basis

(without EVAL-CED1Z); however, in this case the user must provide the required interface signals.

HARDWARE DESCRIPTION

POWER SUPPLIES

The EVAL-AD7764/5EDZ must be powered using a power supply that applies a 7.5 V between the V+ and GND terminals of

Connector J2.

This 7.5 V supply is then regulated on board using ADP3330-

2.5 ADP3330-5 devices (U5 and U3) to provide the 2.5 V and 5 V signals required by the AD7764/AD7765 device.

A filter path of the 2.5 V supply is used to power other digital functionality on the EVAL-AD7764/AD7765EDZ excluding the

AD7764/AD7765 device. A separately filtered 5 V supply also supplies the crystal oscillator on the EVAL-AD7764/AD7765EDZ.

The crystal oscillator is provided for customers that wish to use the device in a stand-alone manner where they wish to provide and acquire the digital signals going to and from the AD7764/5 device.

For this case, the user may apply the MCLK sourced from the crystal oscillator. Note that in the default mode the AD7764/5 evaluation board is set up so that the EVAL-CED1Z board provides the MCLK signal to the ADC as well as providing and acquiring all other digital signals for the evaluation system.

DIFFERENTIAL INPUT

The differential input to the AD7764/AD7765 device is applied through the connector marked J1. This is an XLR audio standard connector. The differential inputs are routed through the AD7764/AD7765 on-board differential amplifier using the external circuit components as detailed in the schematic as shown in this technical note and the AD7764/AD7765 data sheets.

REFERENCE CIRCUIT

The AD7764/5 evaluation board uses the low noise ADR444

(4.096V) reference to supply the ADC. See Gerber files on


AD7764/5 product pages on www.analog.com for details on the layout and configuration for this reference supply.

STANDALONE OPERATION

The EVAL-AD7764/AD7765EDZ can be used in a standalone manner (that is, without using the EVAL-CED1Z). In this case, however, the user must provide all the required interface communications and be able to provide a means to acquire the output.

SMB footprints, allow for external MCLK, SYNC, RESET and

Decimation rate signals to be applied to the AD7764/65 device. All other digital signals are accessible either from the 34-pin header

(J4) or from the marked test points on the evaluation board.

DECOUPLING AND LAYOUT RECOMMENDATIONS

The data sheets of the AD7764/AD7765 devices contain specific information about the decoupling and layout recommendations required to achieve the optimum specifications.

The EVAL-AD7764/AD7765EDZ adheres to these recommendations and is designed as the blueprint for users of the

AD7764/Ad7765 devices.

The EVAL-AD7764/AD7765EDZ are 4-layer boards. One layer is a dedicated ground plane. All supplies to devices on the

EVAL-AD7764/AD7765EDZ are decoupled to this ground plane. In addition to the PCB’s top and bottom layers, there is also a layer for routing power signals. All layers of the board are detailed in the Evaluation Board Schematic and Artwork section.

Interface”), which is on the under side of the EVAL-

AD7764/AD7765EB evaluation board to the SPORT header of the EVAL-CED1Z board. The SPORT header is located on the left hand side of the EVAL-CED1Z board and is marked in the silkscreen.

Figure 10.Connecting the EVAL-AD7764/AD7765 board to EVAL-CED1Z.

5. Start the EVAL-AD7764/AD7765EDZ software.

The differential input to the AD7764/AD7765 device can be connected to the black connector XLR connector (J1) marked

“Differential Input.” This differential input is routed to the inputs of the AD7764/AD7765/ on-board differential amplifier. As the software will power up the AD7764/5 device it is advisable that users do not apply an analog input until the device is fully powered up.

With the hardware set up, you can now use the software to control the EVAL-CED1Z and the AD7764/AD7765 evaluation board. To launch the software, from the Analog Devices menu click on the AD7764_5 submenu, then click on the AD7764_5

icon.



Note: In the case where an Error message appears, click OK and restart the application after checking the connection between the adapter board and the USB port on the PC. Also, check that the USB device is identified by the Device Manager as detailed


in the first time use of EVAL-CED1Z paragraph of Installing the

Software section.



SOFTWARE INSTRUCTIONS FOR NORMAL USE

Once the initial software installation has been completed, follow these instructions for the general setup of the evaluation software each subsequent time the system is used.

Note that the hardware must be powered up as per the

Hardware connections section before attempting the following steps.

1. The download default location for the EVAL-AD7760/

AD7762/AD7763EDZ evaluation software can be found by clicking Start > All Programs > Analog Devices >

AD7764_5

> AD7764_5. If a location other than the default was used, follow the path that was entered during setup.

2. The evaluation software GUI appears.

3. Select the correct AD776x device from the drop down menu in the top left hand corner of the GUI. i.e. AD7764 for AD7764 evaluation, click AD7765 for AD7765 evaluation.

4. The AD7764/5device under evaluation should power up automatically when the software is run. Click the Power


Mode drop down menu, and select either ‘Low Power’ or

‘Normal Power’. This will automatically prompt the EVAL-

CED1Z to write to the AD7764/AD7765 registers and set the power as per your preference for the AD7764/5 device.

5. Note that the external voltage supply connected to the

EVAL-AD7764/AD7765EDZ board will show the current dropping when you switch between ‘Normal Power’ mode,

‘Low Power mode and “Power Down” mode. Seeing these current draw levels change, when switching between the power modes also verifies that the communication between the EVAL-AD7764/5EDZ and EVAL-CED1Z boards.

6. The user can specify the power mode, decimation rate, and number of samples to be acquired (typically 65536 samples) by using the drop-down menus on the software front panel circled in red in Figure 11. The software allows the number of samples specified by the user samples to be viewed as a waveform, histogram, or FFT. The Front panel is shown in Figure 11.

Figure 11. EVAL-AD7764/AD7765EDZ Evaluation Software

Front Panel Features



7. For the initial operation of the AD7764 and AD7765 versions of the evaluation board, set the Decimation Rate to 64 or

128 respectively in the front panel of the AD7764_5

Evaluation Software

dialog box. These are the default decimation rate of the AD7764/

AD7765 parts on reset and power-up of the evaluation board.

8. As well as offering the user different decimation rates the front panel software also allows the user to select the MCLK frequency being applied to the AD7764/5 device. Options include 40MHz, 30MHz, 25MHz, and 20MHz. After selecting any of these MCLK frequencies, please monitor the MCLK test point on the evaluation board to ensure the MCLK has changed in accordance with what you have selected on the front panel GUI before pressing the Sample or Continuous buttons to acquire samples.

9. To show samples output by the EVAL-AD7764/5/EDZ evaluation board Click Sample or Continuous. Clicking

Sample

gives one set of samples, the length of which is determined by the Number of Samples selection on the software front panel. Clicking Continuous shows continuously updated samples of the analog input to the device.

Figure 12. Sample and Continuous Front Panel Buttons

10. It is important to ensure that the frequency of the FSO pulse on an oscilloscope (at the test-point marked FSO) is checked so that it matches the frequency shown in the

Frequency

text box on the software front panel.

11. If at any stage these do not match, reset the AD7764/AD7765/ evaluation board by pressing the RESET push button on the


evaluation board or using the RESET button on the software front panel. Then set the decimation rate on the software front panel to the correct default value.

12. The AD7764/5 software front panel also shows the status bits corresponding to the final sample in the batch of samples shown on the screen. The status indicator- marked

“ADC Status Bits” correspond to the final 8 bits output in each conversion result, and indicate the power mode, over voltage inputs and Filter Settle information.

13. The AD7764/5 software also allows the user to program the Overrange and Gain correction registers. The write functions for these registers are located in the top right hand corner of the GUI. The default Gain of the AD7764/5 is set to 1.25. Changing this value allows the user to digitally alter the gain of the conversion result, as it is output from the AD7764/5 device.

14. Programming the Overrange register allow the user to set a threshold whereby any signal sampled which passes this threshold will set off a flag on the overrange bit and overrange register bit as detailed in the AD7764/5 datasheets.

15. Both of these registers can be read to verify the value written to the ADC. The Read function and indicator for each register are located directly below the write functions.

SOURCE FPGA AND LABVIEW CODE

The FPGA source code for the EVAL-AD7764/5EDZ system is available from the AD7764 and AD7765 product pages by clicking on the Evaluation tools link. This FPGA code can be used as example code for users wishing to build their own interface to the AD7764/5 devices. The source Labview code for the evaluation software is also available to users wishing to incorporate the AD7764/5 conversion outputs as acquired by the CED board into their own Labview analysis routines.
