| COMMUNICATIONS COMPONENTS 2.5 Gb/s Front-Illuminated APD Chip Key Features * Front illuminated device for ease of assembly, with 53 micron diameter active region * -40 to 85 C operating temperature range * -33 dBm typical sensitivity (TIA dependent) * Better than -6 dBm overload performance (TIA dependent) * Uses proven, highly reliable JDSU APD designs Applications * GPON * SONET OC-48 * Ethernet The JDSU 2.5 Gb/s front-illuminated avalanche photodiode (FI-APD) is designed for Gigabit Passive Optical Networks (GPON) that enable data transmissions for fiber-to-the-home (FTTH) offerings. As a result of their internal gain, APDs can significantly enhance receiver sensitivity relative to a standard PI photodiode. This FI-APD uses JDSU proprietary APD designs known for their superior reliability. The dark current at 95% of breakdown voltage is typically in the subnano-amp range. It has an optical window of 53 m, and a remote metal bond pad of 60 m. The FI-APD has an operating temperature range from -40 C to 85 C, and the sensitivity with a low noise TIA can reach -33 dBm. All APD chips come from wafers that have JDSU qualifed. Qualification includes burn-in and functional testing of a sample quantity of chips from each wafer.. Each die shipped is tested at 25 C. Compliance * Fully qualified for Telcordia GR-468-CORE * RoHS compliant NORTH AMERICA: 800 498-JDSU (5378) WORLDWIDE: +800 5378-JDSU WEBSITE: www.jdsu.com 2.5 GB/S FRONT-ILLUMINATED APD CHIP 2 Dimensions Diagram: P-side (Specifications in m unless otherwise noted. ) A1 60 m 53 m Die size 250 m x 250 m Die thickness 125 15 m Optical window O53m Metal bond pad O60m P-metal Ti/PtAu (500/500/6000 A) N-metal AuSn (1000 A) An identification number appears on p-side of chip B2 250 m Absolute Maximum Ratings Parameter Soldering temperature APD voltage supply (VAPD) Maximum optical input power Reverse current Forward current ESD threshold (HBM) Storage temperature Operating temperature 250 m Minimum Maximum 250 C Vbr V 3 mW 5 mA 10 mA 300 V -40 C -40 C +100 C +90 C Specifications Parameter Electrical / Optical 1 Diameter APD responsivity Breakdown voltage, Vbr Vbr temperature coefficient Total dark current APD gain Bandwidth Capacitance Operating Conditions Operating wavelength Operating temperature Overload Test Conditions Minimum Typical Maximum =1550 nm, M=1 Id=10 A Vbr-2 V Vbr-2 V, Po=1 W M=9, Po=1 W Vbr-2 V, f=1 MHz 0.85 A/W 33 V 0.1%/C 9 3 GHz 1260 nm -40 C -6 dBm 53 m 1 nA 10 - 53 V 0.3%/C 10 nA 0.6 pF 1575 nm +90 C - 1.

The wafer qualification includes electrical, optical, RF and 168-hour reliability testing. In accordance with Telecordia GR-468-CORE, each shipped bare die is fully tested at 25 C, including breakdown voltage and dark current at Vbr-2V. JDSU recommends that all assembled devices be burned in prior to installation. Electrostatic Discharge (ESD) Take precautions to protect the FI-APD from ESD during handling. Failure to do so may result in damage to product.
