1 Introduction

he FMC-PLUS-QSFP-DD is a VI A 57.4 compliant Single Width HSPC FMC Plus module, designed for use

with Alpha Data's VI A 57.4 compliant carrier cards. It provides the user with the connectivity to implement

high-speed serial IO communication applications.

his adapter board provides the connection between the FPGA card and industry standard 3xQSFP Double

Density connectors.

Maximum total bandwidth = 600Gbps (28Gbps per channel per direction)

Figure 1 : FMC-PLUS_QSFP-DD Image

Key Features

• FMC (VI A 57.4) electrically compliant

• he FMC-PLUS-QSFP-DD module is based on VI A 57.4 but does not adhere the mechanical

specification(Region 1 of VI A 57.4 is extended to 7.1mm from 5.2mm and the IO Area is extended both in

width and depth to be able to fit the 3xQSFP-DD connectors)

• Air cooled compatible

• Each cage has 8 lanes of up to 28Gbps Serdes capable of 2x100GE, or 8x10GE, and many other

signaling standards

• Operating temperature range from 0 to 55 degrees Celsius

• Compatible with active optical cables

2 High Speed Serial IO (HSSIO)

2.1 User Clock

he user can specify a custom clock frequency from the on-board Programmable Oscillator With Internal

EEPROM(LMK61E2) that is directed to the FPGA banks associated with the high speed serial signals from this

module. his enables support for a multitude of high speed serial IO communication protocols.

2.2 Connectors

he QSFP DD connectors on the FMC-PLUS-QSFP-DD offers the user a wide selection of interconnect

schemes that break out the multi-gigabit transceivers on the FPGA.

Receptacle

• QSFP-DD connector/cage system: Molex part number 202718-0100

2.3 Mating Cables

Below is a list of possible mating cables for the QSFP-DD receptacle/cage:

Cable Solutions

• For passive cables use Molex 2015911005 or similar

3 Installation

he FMC-PLUS-QSFP-DD is designed to plug into the FMC+ front panel connector on a compatible carrier. he

retaining screws should be tightened to secure the FMC+.

he FMC-PLUS-QSFP-DD it should be removed in a certain way for the FMC+ connector not to be damaged.

Here is a video from Samtec showing the removal procedure of this kind of connectors: see https://

vimeo.com/158484280

Note:

his operation should not be performed while the host carrier is powered.

3.1 Handling instructions

Observe precautions for preventing damage to components by electrostatic discharge. Personnel handling the

board should take SSD precautions and avoid flexing the board.

3.2 IO Voltage Selection

he required IO voltage range (VADJ) for the FMC+ is 1.2V to 3.3V. his is stored in a ROM on the FMC+, as

per VI A 57.4 for automatic configuration of supplies. he carrier is responsible for detecting and setting the IO

voltage accordingly.
