WiMAX Pole Mount Beamformer

DESCRIPTION: This involved design was made by designing and connecting four unique circuit card assemblies, and a large pole-mount conduction cooled chassis. The complex electronics relied on several Xilinx® FPGAs, a Freescale® processor, multiple -48V isolated converters, a great deal of analog circuitry, including ADCs and DACs, RF circuitry (2.5 and 3.5GHz), and high-speed serial links.

One of the most elegant solutions within this design was the RF connection block that allowed multiple SMP RF connectors to blind mate directly to the antenna array.

A device enabling complete remote Server Management (monitoring, KVM, Power, etc.) for mission critical infrastructure

DESCRIPTION: This 133MHz, 64-bit PCI add-in card was designed to PCI Specification and is used to provide remote access control and maintenance of high-end servers. Capable of providing remote KVM services, and operation that is truly independent of the host state (including power), this card allows the remote system administrator to recover failing or failed hosts.

This product family features video capture and forwarding functions, USB, Ethernet, and PS2, interfaces. One of the highlights of this design was the power architecture which enabled the PCI card to run from PCI power or a wall adapter or battery back-up, and the ability to intelligently select and seamlessly switch between any power source. Intelligence was provided by an Intel® processor, an Intel non-transparent bridge, and a Xilinx® FPGA.

INDUSTRY: Computing

A Solid-State Drive (SSD) for high-end, low-latency applications. Both SATA and SAS, 2.5”/3.5”, supported

DESCRIPTION: This rigid flex design was destined for high-end computer use. There were numerous signal integrity concerns related to a large number of high-speed multi-drop buses and the limited layer stack supported by the flex circuitry. There were also major power integrity concerns, as the overall package size and target cost could not support a generic spattering of decade capacitors; the power plane impedance was modeled, and a minimal number of capacitors were selected and precisely placed. In addition, the multi-gigabit interface and power inputs had to be proven to be extremely robust. Then, to top things off, a convection system was unacceptable, so we had to deal with all of the challenges of a fully conduction cooled design.

TECHNOLOGIES: Undisclosed.

INDUSTRY: Consumer

A GSM/Satellite phone for emergency applications for people working in remote locations

DESCRIPTION: This unit features an LCD, GSM, Satellite, GPS, and Bluetooth functionality all in a Li-Polymer powered handheld unit. The most challenging aspect of this project was obtaining excellent wireless performance with so many wireless protocols/antennas in such a small size. Fidus’ hardware, signal integrity, and antenna experts sized it all up, and made it work.

High-performance, miniature, ZigBee Module that enables 3rd party ZigBee designs

DESCRIPTION: Fidus created this tiny ZigBee® module to be used within our customer’s wireless HVAC control product line. The design, based on an Ember® controller, offered excellent performance and range utilizing a simple whip antenna that was also designed by Fidus.

This design demanded small size, extremely low-power, and low-cost. To keep costs to a minimum, Fidus worked with the crystal manufacturer to ensure that a standard crystal could be used, while still meeting the RF center frequency requirements. For further cost savings we restricted the layer count to 2, and ultimately replaced the whip antenna with a printed antenna.

This board allowed our customer to validate I/O operation, internal register operation, and characterize their IC across temperature.

In this type of development, we minimize the support circuitry so that we can minimize project cost, schedule, and risk. This includes utilizing off-the-shelf system on modules (SOMs; in this case a RabbitCore®) in conjunction with simple GUIs, to control the ASIC.

FPGA code to interface a Mixed Signal Daughter Board to an FPGA Development Platform

DESCRIPTION: We were requested to develop FPGA code to enable a high-performance ADC (analog-to-digital converter) daughterboard to interface to an Altera® Stratix IV® evaluation board. This solution accomplishes two things: It provides our customer with an additional method of evaluating and experimenting with their chipset, and, it provides a piece of IP that their customers can directly incorporate into their end design.

TECHNOLOGIES: Altera® Stratix IV®, SignalTap®, DC1564A, HSMC, FMC, DDR, LVDS


Proof-of-Concept desktop device that enables gamers to play in the newest, highest video resolutions and at the fastest frame rates

DESCRIPTION: The design utilized a DVI-D connector as well as a DVI-I connector. The DVI connectors were the connections to the outside world and directed data into and out of an FPGA. Both sides relied on a TMDS transceiver, and the analog portion of the DVI-I was accomplished using a Dual DAC. The FPGA was responsible for processing both the high-speed video data as well as the DDC (I2C) bus.



Video Demonstration for tradeshows showing the benefits of FPGAs in multi-image processing and picture-in-picture display. This technology translates to video broadcast and pro-sumer applications

DESCRIPTION: We took a Xilinx® ML605 development kit, an Avnet® HDMI FMC card, and a Panasonic® 1080p60 streaming camera, and made a video demo. The demo is set-up by recording four independent hi-def feeds into the onboard DDR3 memory. We then placed all four videos on the screen at one time, so before we store them into memory, we scale the feeds, and then dump them into memory. Next, we start the camera streaming live video. This live video is scaled, and overlayed onto the four simultaneous video playbacks. Building on this, we also decided to smoothly move the live video feed around the screen, rebounding as it comes to the edge of the display; all at full high definition 1080p60 rates.

This system consists of a Xilinx® MicroBlaze® soft core, a DDR3 memory controller, and a whole bunch of custom scaling, overlay, video processing, and movement code.

This solution has since been ported to the Xilinx® KC705 development kit.
