An open, modular ARM + FPGA development platform featuring the new SYZYGY standard for high-performance peripherals

As Featured In

Electronic Engineering Journal

"The goals with SYZYGY were to provide broad peripheral support, with high speed single-ended as well as differential interface standards, to maintain FPGA pin economy by offering a moderate pin count for small, single-purpose peripherals..."

Embedded

"SYZYGY is intended to fill the need for a compact, low cost, low pin-count, high-performance connectivity solution between FPGAs and single-purpose hardware peripherals."

Samtec

"SYZYGY bridges the gap between Pmods and FMCs."

Xilinx

" In creating the SYZYGY open standard, Opal Kelly is shooting for a “Goldilocks” I/O standard that’s 'just right.'"

LinuxGizmos.com

"SYZYGY bridges the gap between Digilent’s low-speed Pmod connector and the higher-end VITA 57.1 FMC (FPGA Mezzanine Card) standard."

A B Open

"Designed to coexist with existing interconnection standards including PMOD and FMC, Syzygy is claimed to be entirely vendor-agnostic and compatible with products from all major FPGA manufacturers including Xilinx, Intel, Lattice, and Microsemi. "


The Brain-1 is a launch platform for Opal Kelly’s SYZYGY open standard for high performance FPGA peripheral connectivity. SYZYGY fills the need for interconnectivity between Digilent™ Pmod and VITA 57.1 FMC that accommodates high performance peripherals. The Brain-1 is the first realization of a carrier board supporting SYZYGY.

We hope the Brain-1 is just the start of what will become a vibrant ecosystem of high performance, professional-grade peripherals for FPGAs. By making the Brain-1 and our first peripheral assortment open source, we intend to vigorously encourage additional contributions to the carrier and peripheral ecosystem by other manufacturers and engineers.

SYZYGY is intended for applications such as those listed below. The Brain-1 is intended as a general-purpose development platform enabling exploration and implementations in all of these areas:

  • Data Acquisition
  • Machine Vision
  • Digital Communications
  • Software Defined Radio (SDR)
  • Video Output
  • Multi-channel I/O
  • Sensors
  • Robotics

Who Needs the Brain-1?

Academics - Student engineers who need to integrate a system for experimentation or research. Their focus is on the system and not the carrier, so they would prefer to use an off-the-shelf carrier like the Brain-1. Their application may be a mix of off-the-shelf and custom-built peripherals.

Semiconductor Manufacturer - They have built a fancy new data acquisition device or MEMS sensor and want to get it into the hands of their customers for evaluation. SYZYGY is an awesome platform for evaluation deployment since the Brain-1 is low cost and open source, the SYZYGY standard is free to license, and peripherals are high performance and cost effective.

Professional Engineer - Professionals can accelerate the development of their system using off-the-shelf components, an off-the-shelf carrier (Brain-1), a standardized connector (SYZYGY), open source systems, and they can add custom peripherals to the system with relatively simple PCB design requirements (SYZYGY peripherals don’t require any complex PCB fabrication or assembly).

Serious FPGA Enthusiast, Hacker, High-end Hobbyist - Brain-1 is an excellent platform for the serious FPGA enthusiast. While a Zynq-based platform running Linux is nothing new, Brain-1 is the first approachable platform with an existing and expanding ecosystem of off-the-shelf high performance peripherals backed by an open standard which encourages proliferation and adoption.

Who is Opal Kelly and What is SYZYGY?

Opal Kelly was founded in 2004. We have released dozens of Xilinx and Altera FPGA modules that primarily use USB or PCI Express to communicate between peripheral hardware and a host computer. Our products have ended up in professional grade test equipment, industrial machine vision cameras, Doppler radar installations, CT scanners, semiconductor evaluation boards, cutting edge scientific equipment, and all sorts of other things. Our customers use our products in one-off exeriments and multi-thousand unit deployments because we make their lives easier and allow them to focus on the science and engineering that makes their product unique.

SYZYGY is an open standard for connecting FPGAs to peripherals. It is the result of dozens of customer conversations, brainstorming sessions, peripheral analyses, and meticulous design. We’ll share more about the SYZYGY origin story in our updates.

In the meantime, you can learn more about SYZYGY and download the specification at SYZYGYfpga.io.

Why SYZYGY?

Opal Kelly has been producing high quality FPGA integration modules since 2004. While most of our customers assemble their systems by building custom hardware based on our modules, many of them would love to build prototypes and even full-scale integrated systems using off-the-shelf hardware. Our customers have worked with hundreds of high performance peripherals like ADCs, DACs, image sensors, audio CODECs, etc. Unfortunately, the lack of a unifying peripheral standard has been a hurdle to integrating these devices with off-the-shelf evaluation products.

Our interactions with thousands of these customers encouraged us to develop SYZYGY, an open standard for high performance FPGA peripheral connectivity. Existing standards were either inadequate (Digilent™ Pmod) for the performance requirements of desired peripherals or overly complex (VITA 57.1 FMC) for use in cost-effective systems. In other words, we found that our customers wanted something higher performance than Pmod, but smaller scale than FMC.

Adoption of the SYZYGY standard will allow us to offer products for our customers that can support a wide range of high performance peripherals without the expense of FMC or the duplication of effort present in custom solutions. This saves countless hours of engineering for all parties involved and reduces overall system cost, lowering the barrier to entry of these devices.

Furthermore, we hope this work encourages semiconductor manufacturers to adopt the SYZYGY standard for evaluation products as this would serve a two-fold benefit. First, it would bring some greatly appreciated consistency to the large quantity of evaluation boards available. Second, it would expand the usefulness of those evaluation products beyond mere evaluation - to full integration into prototypes and small quantity system production.

Modular Approach

Brain-1’s adoption of the SYZYGY standard enables a modular approach to system design. Modules can connect to Brain-1 directly (with optional mounting hardware) or via high performance cabling. Power, ethernet, USB OTG, and USB serial console connectors are on-board, so there’s no need for additional attachments.

Our first round of SYZYGY peripherals has been in the lab for several weeks now. We made a few tweaks and adjustments and some of them had to go through a second revision prior to production. This round of peripherals will be part of the initial campaign. Additional peripherals are presently being designed and will be released after the campaign. We’d love to get your feedback to help channel our resources. Please email us at syzygy@opalkelly.com if you have any suggestions.

Campaign Peripherals

The following peripherals have already been designed, tested, and are either ready for production or are in the midst of adjustments for revision 2.

Peripheral Description
ADC-LTC2264 40 MSPS, 12-bit dual ADC based on the Linear Technologies LTC2264
DAC-AD9116 125 MSPS, 12-bit dual DAC based on the Analog Devices AD9116
CAMERA 3.4 Mpixel color image sensor based on the ON Semiconductor AR0330

Planned Peripherals

Phase 2 peripherals are presently in design or planned. These will be announced and released during and after the campaign, but will not be part of the original campaign. Your feedback is welcome here! Since SYZYGY is an open standard, we also hope other manufacturers will contribute to build a vibrant ecosystem.

Peripheral Description

SENSORS WIP - GPS, gyro, accelerometer, pressure, humidity, temperature
MIC-ARRAY Audio microphone array for use in beamforming projects
ROBOTICS Robotics platform with motor and servo drivers
AVKIT An audio-visual kit with HDMI output and stereo audio CODEC
ADC-GSPS Ultra high-speed (GSPS) data acquisition using JESD204B

SYZYGY Cables

One of our design goals when creating SYZYGY was to provide a cabling option. We knew that high performance was going to require an expensive cable but we thought we could limit costs by conserving on conductor count. Even a short FMC (VITA-57) cable can cost nearly $900. SYZYGY Standard cables are available for under $45 in low volumes and SYZYGY Transceiver cables are available for under $90. While these are certainly higher cost than the typical ribbon cable, there are some key things to consider. To be honest, we were pleasantly surprised with the pricing indicated in our first RFQ.

  • Each Standard cable is multi-conductor coaxial cable so that each conductor is impedance controlled. This results in cabling that can be used for high speed over great lengths using LVDS or CMOS signal levels.
  • Each Transceiver cable is multi-conductor twin-axial cable so that each pair of conductors is impedance controlled as a differential pair. This results in general purpose cabling that is useful for gigabit transceiver standards over an incredible bandwidth.
  • Despite the high quality and signal integrity, Samtec makes these cables to order and the scale and efficiency of their operation makes them incomparable in the industry by price.
  • At higher volumes, the standard cables start around $19 and the transceiver cables around $38 for 6-inch cables.

Manufacturing Plan

Opal Kelly has been manufacturing products since 2004. We’re very comfortable working with supply chains and our manufacturing partners. We’ve been working with the first revision of Brain-1 since earlier this year and are currently testing the second revision which we expect to be the production version. We have raw materials in-house to build the first batch once we get the green light from engineering. And we’re ready to order more as the volumes increase.

Shipping & Fulfillment

Orders placed through this campaign and Crowd Supply will be fulfilled by Crowd Supply and will ship from their Portland, Oregon warehouse. Opal Kelly is also located in Portland, so logistics between Opal Kelly and Crowd Supply should be reliable. For more information about order processing and fulfillment, please see this Crowd Supply Guide page.

Risks & Challenges

Our past product releases have mostly sold to pilot customers who adopt our products and design them into their products. This lead-in period can be a few months to several months depending on the product. The Brain-1 is our first crowd-funded campaign. If the popularity exceeds our expectations, we would need to manage part acquisition lead times, but we already have a good handle on what that would mean.

Simply put, we don’t expect any major hurdles here. The biggest challenge is if this is wildly popular and we end up with a few months lead time for larger quantities. Even in this situation, many devices would deliver in 1Q‘2018 and we would expect the remainder to deliver in 2Q‘2018.
