IEEE 1394b S200 Transceiver Pair

PRELIMINARY PRODUCT SPECIFICATION

FDL300E/FDL300D

650 nm 250 Mbps

Fiber Optic Transceiver Solution

for Seamless Digital to Light/Light to Digital Conversion

FEATURES DESCRIPTION

• Meets the IEEE 1394b S200 (250 Mbps) specification Firecomms RCLED-based 650 nm fiber optictransceiver (FOT) solution provides a seamless digital media to red light conversion, and subsequent recovery for performance at maximum speed in POF applications such as IEEE 1394b S200. The FOTs operate at LVDS signal levels directly compatible with IEEE 1394b PHY ICs.The FOT solution pairs Firecomms RCLED (ResonantCavity Light Emitting Diode) technology with an encapsulated driver IC for coupling digital media signals to light in a POF link. At the receive side, thesolution provides a 250 Mbps capacity light receiver in an integrated package that recovers digital media compatible signals (IEEE 1394 LVDS). The integration of the emitter Tx FOT with its driver IC and a pin-diode Rx FOT with a receiver IC in a POF link provides for a high-integrity digital data link over a range of up to 50m at 250 Mbps (S200), depending on installation conditions. • Integrated CMOS driver IC • Resonant Cavity LED at red 650 nm with small emissionaperture suitable for Plastic Optical Fiber (POF) • Resonant Cavity LED reliability tested to over 400,000hours lifetime • Configured for IEEE 1394b with LVDS I/O • High sensitivity receiver IC and pin-diode for one-step light to digital conversion • Compatible with SMI connector form factor • Integrated optics to efficiently focus and direct light • Ultra-low power consumption
