Support Support Not connected 2 2000-12-19 V23826-K305-Cxx/Cxxx Description Description The Infineon multi mode transceiver is based on the Physical Medium Depend (PMD) sublayer and baseband medium, type 1000BASE-SX (Long Wavelength Laser) (IEEE 802.3z) and complies with the Fibre Channel Physical and Signaling Interface (FC-PH), ANSI XSI TT Fibre Channel Physical Standard Class 100-M5-SLI, latest Revision. The appropriate fiber optic cable is 62.5 m or 50 m multimode fiber with Duplex SC connector. The Infineon multi mode transceiver is a single unit comprised of a transmitter, a receiver, and an SC receptacle. This design frees the customer from many alignment and PC board layout concerns. The module is designed for low cost LAN, WAN, Gigabit Ethernet, and Fibre Channel applications. It can be used as the network end device interface in mainframes, workstations, servers, and storage devices, and in a broad range of network devices such as bridges, routers, intelligent hubs, and local and wide area switches. This transceiver operates at 1.0625 Gbit/s and 1.3 Gbit/s from a single power supply (+5 V or 3.3 V). The full differential data inputs and outputs are PECL compatible.

Automatic Shut-Down LEN TD TD Laser Coupling Unit Laser Driver e/o Laser Power Control o/e Multimode Fiber Monitor RD RD SD Figure 2 Rx Coupling Unit o/e Receiver Functional Diagram The receiver component converts the optical serial data into PECL compatible electrical data (RD and RDnot). The Signal Detect (SD, active high) shows whether an optical signal is present. The transmitter converts electrical PECL compatible serial data (TD and TDnot) into optical serial data. The following versions are available: 1 AC/DC Transceiver: Tx is AC coupled. Differential 100 W load. Rx has standard PECL output and is DC coupled. 2 AC/AC TTL Transceiver: Tx and Rx are AC coupled. Tx has differential 100 W load. Signal Detect is TTL compatible. 3 DC/DC Transceiver: Standard PECL inputs and outputs Tx and Rx are DC coupled. 4 AC/AC PECL Transceiver: Tx and Rx are AC coupled. Tx has differential 100 W load. Signal Detect is PECL compatible. Data Sheet 4 2000-12-19 V23826-K305-Cxx/Cxxx Description The transmitter contains a laser driver circuit that drives the modulation and bias current of the laser diode. The currents are controlled by a power control circuit to guarantee constant output power of the laser over temperature and aging. The power control uses the output of the monitor PIN diode (mechanically built into the laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the operating limits. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. A reset is only possible by turning the power off, and then on again. The transceiver contains a supervisory circuit to control the power supply. This circuit generates an internal reset signal whenever the supply voltage drops below the reset threshold. It keeps the reset signal active for at least 140 milliseconds after the voltage has risen above the reset threshold. During this time the laser is inactive.

Data Sheet 8 2000-12-19 V23826-K305-Cxx/Cxxx Eye Safety Eye Safety This laser based single mode transceiver is a Class 1 product. It complies with IEC 60825-1 and FDA 21 CFR 1040.10 and 1040.11. To meet laser safety requirements the transceiver shall be operated within the Absolute Maximum Ratings. Attention: All adjustments have been made at the factory prior to shipment of the devices. No maintenance or alteration to the device is required. Tampering with or modifying the performance of the device will result in voided product warranty. Note: Failure to adhere to the above restrictions could result in a modification that is considered an act of "manufacturing", and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (ref. 21 CFR 1040.10 (i)).

Electromagnetic emission may be caused by these components. To prevent emissions it is recommended that cutouts for the fiber connectors be designed as small as possible. It is strongly recommended that the Tx plug and the Rx plug be separated with a bar that divides the duplex SC opening. If shielded parts are employed, they should be in proper contact with the bezel (back plane). Since the shield is galvanically isolated from signal ground it is strongly recommended to prevent any contact between shield and the circuitry i.e. even any ground connection on the pcb may be harmful to EMI performance. In cases where EMI performance becomes critical it has proven to be helpful when using SC-plugs with less metal parts inside (as Infineon fibers).
