FMC/FMC+ Standard Connectors

Silicon Development Solutions


FAMILY OVERVIEW

FMC Standard

The FPGA Mezzanine Card (FMC) was developed and ratified by a consortium of FPGA vendors and end-user members of the VITA 57 working group. FMC is an ANSI standard which defines a compact electro-mechanical expansion interface for a daughter card to an FPGA baseboard or other device with re-configurable I/O capability.

The FMC Standard is essential for FPGA vendors making baseboards and comprehensive development kits to enable Designers to accelerate their application development. FMC products are continually introduced by Supplier companies for targeted market specific applications in industries such as Datacom, Broadcast, Aerospace/Defense, Industrial and Instrumentation.

FMC Interconnect

VITA standards specify configurations for the VITA 57.4 FPGA Mezzanine Card Plus (FMC+) connector, and the VITA 57.1 FPGA Mezzanine Card (FMC) connector:

FMC+ (VITA 57.4)
  • High Serial Pin Connector (HSPC) with 560 pins (provides 24 GT interfaces)
  • High Serial Pin Connector extension (HSPCe) with 80 pins (provides additional 8 GT interfaces; this connector is optional)
FMC (VITA 57.1)
  • High Pin Count (HPC) 400 I/O high-speed array system
  • Mechanically compatible Low Pin Count (LPC) 160 I/O can also be used with any of the form factors detailed in the standard

The FMC+ and FMC connectors are Application Specific Product (ASP) versions of Samtec's SEARAY™ High-Speed Array system. These FMC connectors are available direct from Samtec and are scalable to high-performance applications as your hardware development effort demands.

Below is a matrix of Samtec FMC+ and FMC interconnect options available for the FPGA Baseboards and Mezzanine Cards. All Samtec board level interconnects and high-speed cable assemblies listed are available direct from Samtec with no Minimum Order Quantity.


FMC+ Connector Options

Building on FMC, FMC+ employs a larger connector from the SEARAY™ family of high-speed, high-density arrays.  This High Serial Pin Connector (HSPC) has 560 pins arranged in a 14x40 array.  While new FMC+ cards can only plug into new FMC+ carriers due to their larger connectors, original FMC cards will also fit thanks to a customized polarization system providing true backward compatibility.

The FMC+ Standard increases the number of multi-gigabit interfaces from 10 to 24.  In addition, there is an optional extension connector (the High Serial Pin Connector extension, or HSPCe) to boost pin-count by 80 positions, arranged in a 4x20 array. This brings the maximum multi-gigabit interfaces to 32 full duplex channels.  Throughput per multi-gigabit interface has increased to 28 Gbps in each direction.

FMC Connector Options

The (LPC) connectors provide 68 user-defined, single ended signals (or 34 user-defined, differential pairs); (HPC) connectors provide 160 user-defined, single ended signals (or 80 user- defined, differential pairs), 10 serial transceiver pairs and additional clocks; (HPC) and (LPC) use the same mechanical connector body - the only difference is which signals are actually populated. Thus, cards with (LPC) connectors can be plugged into (HPC) sites, and if properly designed, (HPC) cards can offer a subset of functionality when plugged into an (LPC) site.

VITA 57 - JSOM

State of the art VPX systems employ FMC/FMC+ mezzanine cards to enhance their versatility.

V57.1 FMC (FPGA Mezzanine Card) utilizes 400-position (10x40) SEARAY™ connectors in 8.5 mm and 10 mm heights.

V57.4 FMC+ (FPGA Mezzanine Card Plus) expands on FMC, increasing its main SEARAY™ connector to 560-positions (14x40). FMC+ adds an optional 80-position (4x20) SEARAY™ extension, maximizing the aggregate pinout to 640-positions per module.

FMC/FMC+ mezzanine applications share a 6 mm pad and a 2.7 mm hole for standoff mounting.

Some VITA FMC/FMC+ mezzanine cards may present a challenge to unmate from their host. To aid in separation, Samtec has developed the JSOM (Micro Jack Screw Standoff). They act as a traditional standoff when collapsed. An Allen-key unscrews and expands the jack screw, dividing the PCBs in a steady, even motion until the mezzanine is safely separated from its host.

The FMC/FMC+ JSOM standoff family includes:
  • M2.5 hardware - Drop-in JSOM for VITA applications
  • M3 hardware – Heavier attachment hardware for rugged applications and development work
  • #4-40 hardware – Heavier attachment hardware commonly used in legacy designs, rugged applications, and development work
  • Versions offered in stack heights of 8.5 mm and 10 mm
  • Versions operate with a 1.5 mm Allen key or driver
  • Offered with or without thread-locker on bottom mounting screw
  • All standoff bodies visibly marked for easy identification

Altera® HSMC

The Altera® HSMC defines electrical and mechanical properties of a high speed mezzanine card interface. This specification standardizes the way in which mezzanine cards communicate and connect to host boards. By taking advantage of the high- performance I/O features found in today’s FPGA devices, manufacturers can build a single mezzanine card that will then interface to multiple host boards.

Similarly, they can build a host board that can leverage many different, pre-built, mezzanine cards. The HSMC connectors defined by the specification are based on the 0.50 mm pitch Q Strip® QSH/QTH series high speed board-to-board connectors from Samtec. The Samtec interconnect for the mezzanine card is ASP-122952-01. See the complete HSMC Specification from Altera for further information and recommendations for running both high-frequency and low speed interface signals within the various “banks."
