AD7760/AD7762 Evaluation Board using

EVAL-CED1Z

EVAL-AD7760/AD7762EDZThe AD7760 interfacing signals are created by the EVAL-CED1Z

board which should be used in conjunction with EVAL-AD7760/2EDZ board to enable data acquisition via the provided

software and USB link.

The EVAL-AD7760/2EDZ board itself includes all routing

required for evaluating the AD7760/2 device.

The MCLK signal for the main device is generated from a

40 MHz crystal oscillator. The user can also choose if required,

to drive the AD7760/AD7762 with an external clock source by

inserting the 0 Ω link to the SMB marked “MCLK”.

The AD7760/AD7762 evaluation board comes with

an on-board FPGA device that is used to interface with the

EVAL-CED1Z board. The combination of the EVAL-AD7760/2EDZ board and EVAL-CED1Z board allied with the

EVAL-AD7760/AD7762EDZ software allows the user to upload

samples taken by the AD7760/AD7762 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-AD7760/AD7762EDZ can also be used on a standalone basis

(without EVAL-CED1Z); however, in this case the user must

provide the required interface and acquisition requirements.

EVAL-AD7760/AD7762EDZSTANDALONE OPERATION

The EVAL-AD776xEDZ 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 data from the

board.

HARDWARE DESCRIPTION

POWER SUPPLIES

The EVAL-AD776xEDZ must be powered using an external 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 ADP3334

devices (U9 and U6) to provide the 2.5 V and 5 V signals required

by the AD7760/AD7762 device. Supplies AVDD2, AVDD3, and

AVDD4 are the 5 V supplies to the AD7760/AD7762 device. A

voltage of 2.5 V. supplies the AD7760/AD7762 pins AVDD1,

VDRIVE, and DVDD.

A separately regulated 2.5 V supply is used to power all digital

functionality on the EVAL-AD7760/AD7762EDZ excluding the

AD7760/AD7762 device. An individually regulated 5 V supply

also supplies the crystal oscillator and clock buffer devices on the

EVAL-AD7760/AD7762EDZ. Setting LK1 to A means that the

MCLK buffer is powered by 5 V, enabling the AD7760/AD7762

device to be operated using an MCLK signal with amplitude of

5 V.

DECOUPLING AND LAYOUT RECOMMENDATIONS

The data sheets of the AD7760, AD7762, and AD7763 devices

contain specific information about the decoupling and layout

recommendations required to achieve the optimum specifications.

The EVAL-AD7760/AD7762EDZ adheres to these recom-mendations completely and is designed as the blueprint for

users of the AD7760, AD7762 devices. The Gerber files for the

EVAL-AD7760/2EDZ board are available for download from

the AD7760 or AD7762 product pages at

The EVAL-AD7760/AD7762EDZ is 4-layer boards. One layer is

a dedicated ground plane. All supplies to devices on the EVAL-AD7760/AD7762EDZ 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.

In addition, the exposed paddle of an AD7760, AD7762 device

is connected by multiple vias to this ground plane. The exposed

paddle is not connected to any of the ground pins on the

AD7760, AD7762 device.

DIFFERENTIAL INPUT

The differential input to the AD7760/AD7762 device is applied

through the connector marked J1. This is an XLR audio

standard connector. The differential inputs are routed through

the AD7760/AD7762 on-board differential amplifier using the

external circuit components as detailed in the AD7760/

AD7762 data sheets.

78kHz to 2.5MHz output data rate from the AD7760.

7. 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. The software allows the number of samples

specified by the user samples to be viewed as a waveform,

histogram, or FFT.

The choosing the different decimation rates from the front

panel controls writes to the AD7760/2 control register 2 to

change the amount of decimation used in the second

internal FIR filter of the AD7760. This filter can be set

bypassed to enable decimate x8 mode or otherwise set to

decimate x2 to x32 in order to enable an overall decimation

rate of 16 to 256 for the AD7760 device.

a) Select the number of coefficients that will be

downloaded – this is half the filter length – so if you

have a 24 tap filter you select 12 in the drop down

selection shown in Figure 13.

DOWNLOADING A USER-DEFINED FILTER

The final stage of the AD7760/2 FIR filter can be programmed

to suit the user’s specific requirements. The filter designed must

correspond with the requirements listed in the datasheet – it

must be a symmetrical filter with an even number of

coefficients. The number of coefficients can be from 12 to 96.

• Due to the symmetry of the filter, the coefficients will

repeat. Thus, only half of the coefficients are required to

be sent to the AD7760/2 device.

• The AD7760/2 software reads the coefficients from a

text file and writes each coefficient to the AD7760/2.

The filter file should contain the correct checksum,

which is also written to the ADC, and the file must be in

the correct format.

14. An example of this format is shown in Figure 12. This

example corresponds to the example digital filter in the

Downloading A User Defined Filter section in the

AD7760/2 datasheet.

15. Each of the 32 bit words (in this case there are 12 words for

the coefficients + the checksum) are in a Hexadecimal

format – there must also be no spaces between the

characters and no text, spaces or notation before or after

any of the hex words to be written. The software

implements a text read from each line of the file and then

translates this value to the correct binary 32 –bit word to

be written to the AD7760/2 as per the description in the

datasheet.

c) Finally click the “Configure Filter” button to

download the user-defined filter.

d) Once this is done then, click the “Sample” button to

acquire a batch of samples from the AD7760/2 device.

e) The filter example used in the AD7760/2 datasheet

will show a slower transition band. The FFT of this

filter implementation is shown in Figure 15. As

highlighted, the status bits output by the ADC will
