ADM7154

The AD-SYNCHRONA14-EBZ is an ideal self-contained device to use in evaluation and prototyping of applications that need a highly accurate frequency and phase-controlled source clock. It is designed around the Analog Devices AD9545 and HMC7044 and greatly simplifies clock distribution and multi-channel synchronization in complex systems. It is intended to be used by trained professionals in a laboratory environment, and not intended as an end product for commercial use. It can be taken as a complete reference design and customised as required for any end customer applications. Full design details are made available free of charge.

The AD-SYNCHRONA14-EBZ comes in a 1U mechanical form factor. Using popular industry connector SMA and TwinAX interfaces most labs will already have the needed cables.

With its internal OCXO it can operate in standalone mode or be fed from a choice of external sources, such as 3 separate high speed differential clock inputs, a 10MHz reference and 1PPS. This flexibility combined with the capability to select either of the internal VCXO options of 100MHz or 122.88MHz, gives almost unlimited choice for the frequency of interest and accuracy needed for a wide variety of application areas.

The AD-GMSL2ETH-SL is an edge compute platform enabling low-latency data transfer from eight Gigabit Multimedia Serial Link™ (GMSL) interfaces on to a 10 Gb Ethernet link. The target applications include autonomous robots and vehicles where machine vision and real-time sensor fusion is critical.

The system includes two MAX96724 Quad Tunneling GMSL2/1 to CSI-2 Deserializers, enabling connectivity to eight GMSL cameras. The video data from the cameras is transferred from the MAX96724 deserializers via MIPI CSI2 interfaces to an AMD KV26 System on Module which implements the logic to aggregate the video data from all the GMSL cameras into a 10 Gb Ethernet link, so that it can be sent to a central processing unit.

The IEEE 1588 Precision Time Protocol (PTP) with hardware timestamping is supported, enabling accurate synchronization with host systems and other edge devices. The AD9545 Quad Input, 10-Output, Dual DPLL/IEEE 1588, 1 pps Synchronizer and Jitter Cleaner is used to generate the required clocks for the 10 Gb Ethernet interface and the PTP logic.

A software networking stack can be used to realize the communication over the 10 Gb Ethernet link. Since the system runs Linux tools like gstreamer can be used to send the video data to a host and remote connection into the system is possible via ssh. The software network stack has limitations in terms of the maximum achievable transfer rate, and for this reason there is also the option to have an FPGA accelerated UDP or TCP implementation with Real Time Transfer (RTP) protocol for data packetization, which can get up to the maximum achievable data rate on the 10 Gb ethernet interface.

Accurate camera triggering control is achieved through dedicated FPGA logic, with configurable frequency and phase as well as selecting the trigger source between the internal logic and external signals.

Sixteen (16) general purpose I/O pins are available with software configurable functionality, operating at 3.3 V voltage level. A RS232 dedicated interface can be used to connect UART peripherals such as GNSS devices.

The design is accompanied by an open-source software stack and FPGA design, and reference applications, enabling custom software development to start from a proven implementation.

The AD-FMCADC4-EBZ is a high speed 4-channel data acquisition board featuring two AD9680 dual channel ADC at 1000 MSPS and four ADA4961 low distortion, 3.2 GHz, RF DGA driving each converter. The FMC form factor supports the JESD204B high speed serial interface. All clocking and channel synchronization is support on-board using the AD9528 clock generator. This product is designed for sampling wide bandwidth analog signals up to the second Nyquist zone. The combination of wide input bandwidth, high sampling rate, and excellent linearity of the AD9680 is ideally suited for spectrum analyzers, data acquisition systems, and a wide assortment of military electronics applications, such as radar and jamming/anti-jamming measures.

The board meets most of the FMC specifications in terms of mechanical size, mounting hole locations, and more. Although this board does meet most of the FMC specifications, it’s not meant as a commercial off the shelf (COTS) board. If you want a commercial, ready to integrate product, please refer to one of the many FMC manufacturers and the FMC specification (ANSI/VITA 57.1).

This board is targeted to use the ADI reference designs that work with Xilinx development systems. ADI provides complete source (HDL and software) to re-create those projects (minus the IP provided by the FPGA vendors, which we use), but may not provide enough info to port this to your custom platform.

The design of the board is specifically tailored to synchronizing multiple AD-FMCADC4-EBZ boards together. For more information on synchronization please refer to A Test Method for Synchronizing Multiple GSPS Converters. The reference design includes the device data capture via the JESD204B serial interface and the SPI interface. The samples are written to the external DDR-DRAM. It allows programming the device and monitoring its internal registers via SPI.

The AD-FREQCVT1-EBZ is an add on board for the FMCOMMS3/4/5 boards which contain the AD9361. While the complete chip level design package can be found on the ADI product pages, information on the card, how to use it, the design package that surrounds it, and the software which can make it work, can be found on the analog wiki site.

The purpose of the AD-FREQCVT1-EBZ is frequency up or down conversion to allow the AD9361 to operate down to 1MHz.

The AD-FMComms11-EBZ board is a system platform board for communication infrastructure applications that demonstrates the Direct to RF (DRF) transmitter and observation receiver architecture. Using high sample rate RFDAC(s) and RFADC(s), a number of components in previous generation transmitters can be eliminated, such as mixers, modulators, IF amplifiers and filters. The objective being to bring the ADC or DAC as close to the antenna as possible, leading to possibly more cost effective and efficient communications solution.

It is composed of multi-GSPS RF ADC and DAC, AD9625 and AD9162 respectively. The transmit path contains a balun, low pass filter, gain block and variable attenuation to produce an output appropriate for a power amplifier module. Along the observation path, the PA output is coupled back into the board through a variable attenuator, a balun and finally the ADC. Clock management is taken care of on board; all the necessary clocks are generated from a reference. Power management is present as well.
