EVAL-AD7760_AD7762_AD7763EBZ| Application Note
Evaluation Board for AD7760/AD7762/AD7763 using EVAL-CED1Z
Preliminary Technical Data
FEATURES
Full-featured evaluation board for the AD7760/AD7762/AD7763 EVAL-CED1Z compatible On-board 4.096 V reference Crystal clock oscillator MCLK source PC software for control and data analysis for use with EVAL-CED1Z
EVAL-AD7760/AD7762/AD7763EDZ
The EVAL-AD7760/AD7762/AD7763EDZ includes a 40 MHz crystal oscillator that provides the MCLK for the AD7760/ AD7762/AD7763 device. The user can also choose, if required, to drive the AD7760/AD7762/AD7763 with a different clock oscillator, or to insert the 0 link so that the MCLK signal is driven using an external clock source via the SMB connector marked MCLK. The AD7760/AD7762/AD7763 evaluation board comes with an on-board FPGA device that is used to interface with the EVAL-CED1Z board. The combination of both the FPGA and the EVAL-CED1Z board allied with the EVAL-AD7760/AD7762/ AD7763EDZ software allows the user to upload samples taken by the AD7760/AD7762/AD7763 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/AD7762/ AD7763EDZ can also be used on a standalone basis (without the FPGA and EVAL-CED1Z); however, in this case the user must provide the required interface signals.
EVALUATION BOARD DESCRIPTION
This data sheet describes the evaluation board for the AD7760/ AD7762/AD7763 - ADCs. The AD7760 is a 24-bit ADC that combines wide input bandwidth and high speed with the benefits of - conversion with a performance of 100 dB SNR at 2.5 MSPS, making it ideal for high-speed data acquisition. The AD7762 and AD7763 derivatives are parallel and serial interface versions, respectively, of the AD7760, with maximum output data rates of 625 kSPS. Complete specifications for the AD7760/AD7762/AD7763 devices are available in the AD7760/AD7762/AD7763 data sheets available from Analog Devices, Inc., and should be consulted in conjunction with this data sheet when using the evaluation board.
