Dynamic Serial Optical Interconnect (DSOI)

This product is a smart optical transceiver that brings fibre to FPGA. It enables the rapid integration of optics into systems that use FPGAs thus reducing NREs and time to market.

A DSOI device.

Where is a DSOI Used?

The DSOI fits into a system where interface logic, such as a bridge, would typically be found.

The DSOI can perform the that interface logic typically takes on and also that of any MAC logic may be attached to it.  In this respect it takes on a similar role to a small FPGA such as Xilinx's^® Spartan^TM 3. However, the DSOI differentiates itself by offering the transparent addition of an optical interface that supports emerging optical standards:

Technical Description

The DSOI is a system-in-package (SiP) transceiver for short range serial optical interconnection.

Programmable protocol technology (PPT) enables protocol agility. Dynamic in-system reconfiguration means that the desired protocol is always supported.

The integration of optical transceiver, passives, serialiser/deserialiser and a field programmable gate array (FPGA) offers a substantial size reduction.

Reduces both cost and time to market for companies incorporating compatibility with emerging serial optical protocols into their existing product range. Previously on-board functionality can be integrated into the FPGA further reducing size and cost.

Proprietary packaging designed specifically with high-volume production and tolerance insensitivity in mind. Uses proven commercial off-the-shelf components increasing reliability and maintaining compatibility. A thermal barrier separates high power devices from the optical head improving stability.

Pin and configuration compatible with Xilinx^® Spartan^TM 3 FT256 devices allowing virtually transparent integration into a broad range of existing systems. Compatible with typical optical interface characteristics including physical and protocol. Compliant with MSA requirements for digital diagnostics (SFF-8472). Monitoring via FPGA or external circuitry.
