Development Kit for Signal Chains Using Quad-Channel ADC Devices

Intended for prototyping work in military, telecommunications, avionics, space, industrial and physics applications, the kit from Teledyne e2v may be used for evaluating the operation of EV12AQ600 and EV12AQ605 12-bit quad-channel ADCs By DA Staff / 07 Jul 2021

Teledyne e2v has expanded the scope of engineering support accompanying its popular EV12AQ60x analog-to-digital converter (ADC) series with the new EV12AQ600-FMC-EVM development kit designed for those implementing mixed-signal subsystems. 

Designed for prototyping work relating to avionics, military, space, telecommunications, industrial and high energy physics applications, this kit may be used for evaluating the operation of the company’s EV12AQ600 and EV12AQ605 12-bit quad-channel ADCs so engineers can quickly construct functioning prototypes and check that the expected operational parameters can be achieved.

Each EV12AQ600-FMC-EVM board features either an EV12AQ600 or an EV12AQ605 device, along with four single-ended signal inputs and a FMC connector for interfacing with an appropriate programmable logic device. 

A high-speed internal clock (supporting 6.4 GHz operation), a 12V-rated power supply unit and an ESIstream serial interface have also been incorporated, plus provision for the connection of an external clock and a temperature monitor.

The kit adds a further dimension to the existing portfolio of hardware based on the EV12AQ60x series. This also includes the previously introduced demo kit and the multi ADC synchronisation kit, both of which have built-in FPGAs. 

By the EV12AQ600-FMC-EVM allowing engineers to add their own relevant FPGA, consistent with what will be specified in their actual system, it is possible for them to begin creating the necessary code at the prototyping stage. This means that they don’t have to start again after the prototyping work has been completed. 

By utilizing the ESIstream interface, there is the possibility for multiple kits to be synchronized together to assist with the development of more complex arrangements, such as phased-array antennas.

The cross-point switch integrated into the EV12AQ60x series is a unique element through which the cores of each EV12AQ600 and EV12AQ605 ADC can be used to sample independently of one another or interleaved together. This results in a 1.6GSps sampling rate when in 4-channel mode, a 3.2GSps rate in 2-channel mode, or a 6.4GSps rate across a single channel. The bit rate and the input analog bandwidth can also be adjusted as required.

The kit is compatible with a wide variety of FPGA plug-in boards from different vendors.
