Introduction
The FMC-PLUS-QSFP-DD is a VITA 57.4 compliant Single Width HSPC FMC Plus module, designed for use with Alpha Data’s VITA 57.4 compliant carrier cards. It provides the user with the connectivity to implement high-speed serial IO communication applications. This 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)
Key Features
- FMC (VITA 57.4) electrically compliant
- The FMC-PLUS-QSFP-DD module is based on VITA 57.4 but does not adhere to the mechanical specification(Region 1 of VITA 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 Series capable of 2x100GE, or 8x10GE, and many other signaling standards
- Operating temperature ranges from 0 to 55 degrees Celsius
- Compatible with active optical cables

High Speed Serial IO
(HSSIO)
User Clock
The 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. This enables support for a multitude of high speed serial IO communication protocols.
Connectors
The 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
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
Installation
The FMC-PLUS-QSFP-DD is designed to plug into the FMC+ front panel connector on a compatible carrier. The retaining screws should be tightened to secure the FMC+.
The 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:
This operation should not be performed while the host carrier is powered.
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.
IO Voltage Selection
The required IO voltage range (VADJ) for the FMC+ is 1.2V to 3.3V. This is stored in a ROM on the FMC+, as per VITA 57.4 for automatic configuration of supplies. The carrier is responsible for detecting and setting the IO voltage accordingly.
