FireFly™ Micro Flyover System™

FireFly™ Micro Flyover System™

Future-proof system with interchangeability of FireFly™ copper and optical using the same micro connector system for up to 28 Gbps per lane in x4 and x12 configurations.


FAMILY OVERVIEW

firefly video

FireFly Micro Flyover System™ is the first interconnect system that gives a designer the flexibility of using micro footprint high-performance optical and low-cost copper interconnects interchangeably with the same connector system.

Samtec FireFly copper and optical cable systems provide the flexibility to achieve higher data rates to 28 Gbps and/or greater distances, simplifying board design and enhancing performance.

Highest Density

The industry-leading miniature footprint of FireFly™ allows for greater density and closer proximity to the IC, which simplifies board layout and enhances signal integrity. Performance from 14 Gbps to 28 Gbps can be achieved in the same footprint covering an area of only 0.63 square inches for an aggregate 265 Gbps/in².

Ease of Routing

The two-piece board level interconnect system consists of a micro high-speed edge card connector, and a positive latch connector for power and control signal communications. Isolating the signal and power in this manner helps ease trace routing, compared to array systems.

UEC5 – High-Speed Edge Card Connector
  • Gen 1 – up to 20 Gbps
  • Gen 2 – 20+ Gbps
UCC8 – Positive Latch Connector
firefly connector systems

Ease of Assembly

The rugged two-piece edge card socket system, with weld tabs, latch locking mechanism, and loading guides, provides simplified mating and unmating of the cable assembly, compared to compression systems, which utilize mechanical screw downs and hardware.

Unlike existing optical engine-based solutions, thermal operating conditions are acknowledged and designed for by including an integral heat sink. This integral heat sink further simplifies the assembly process. Standard heat sinks are available in several designs, including finned, flat, fiber-groove for multi-row configurations, and custom designs, for conduction or convection cooling.

Signal Integrity

By taking the data connections "off-board" with Samtec Flyover® cables, the signal integrity design is made significantly easier, and the electrical performance improved.

Routing data above lossy board materials and other signal degrading components negates the need for the layout complexities that are required to design for high speed signaling.

Development Kits

14 Gbps FireFlyTM FMC Module

Samtec's 14 Gbps FireFlyTM FMC Module provides up to 140 Gbps full-duplex bandwidth over 10 channels from an FPGA to an industry-standard multi-mode fiber optic cable. The optical engines in FireFlyTM provide adjustable power levels to support cable lengths up to 100 m.

As a VITA 57.1 FMC, the module can be used for optical data communication on any FPGA development board supporting high-speed multi-gigabit transceivers. It can run system data or BERT testing on all channels in parallel. This makes evaluation and development with an FPGA much easier and is an ideal substitute for 28G test equipment.

Part Number: REF-193429-01
