FM-S28 Dual QSFP/QSFP+ transceiver FMC

Modular FPGA I/O in FMC (VITA57) module

Enables high-speed serial (fiber optic or copper) connections into an FPGA's MGT interfaces.

Two QSFP/QSFP+ cages supports two (2) QSFP/QSFP+ transceiver modules enabling a wide range of transceivers with signaling rates up to 10Gb/sec per lane.

Optional QDRII SRAM (up to 8M by 18)

Two Programmable reference clocks

  • Direct connections between SFP/SFP+ transceivers and host FPGA ensures maximum throughput and minimum latency
  • Easilty interfaces high-density, high-speed I/O to an FPGA-based host board
  • 2.5V signaling ensures compatibility with Virtex-6 FPGAs


The FM-S28 provides two QSFP/QSFP+ module interfaces directly connected to the carrier card using the differential pairs of the FMC HPC connector. This enables a wide range of full data rate 40 Gigabit Ethernet, Fiber Channel, Infiniband and other very high performance serial standards to communicate with FPGA devices that have built in 10 Gigabit serial transceivers, such as the Xilinx Virtex-6 HXT family. When used with carrier cards with FPGAs that support the standard 3.125 Gigabit/sec. signaling rates, 10 Gigabit Ethernet and similar standards are supported using LX4 style methods. Most functions of the FM-S28 support a range of Vadj from 1.8 to 2.5 V. This enables the serial transceivers, clock generators, EEPROM and LEDs to work with various Spartan-6, Virtex-5 and Virtex-6 based carrier cards.

The optional QDR II SRAM interface is 1.8 Volt only and requires a compatible carrier card that supports 1.8 Vadj such as one Faster Technology’s Falcon family. The FM-S28 is electrically compliant with the FMC standard. Due to the size of the QSFP cages, the FM-S28 is classified as a mechanical superset of the FMC mechanical standards. Special attention should be paid to ensure that the FM-S28 is mechanically compatible if used with non-supported host carrier cards.
