The appropriate fiber optic cable is 62.5 m or 50 m multimode fiber with duplex SC connector. The Siemens Gigabit Ethernet multimode 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, and Gigabit Ethernet 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. JUNE 1998 This transceiver operates at 1.3 Gbits per second from a single power supply (+5 V or +3.3 V). The full differential data inputs and outputs are PECL compatible. TECHNICAL DATA The electro-optical characteristics described in the following tables are valid only for use under the recommended operating conditions.

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. Launched Power (Average)(1) PO -9.5 Center Wavelength C 830 The transmitter converts PECL compatible electrical serial data (TD and TDnot) into optical serial data. Spectral Width (RMS) Relative Intensity Noise RIN 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.

A reset is only possible by turning the power off, and then on again. 1. Into multimode fiber, 62.5 m or 50 m diameter. 2. Laser power is shut down if power supply is below VTH and switched on if power supply is above VTH after tRES. The transceiver contains a supervisory circuit to control the power supply. This circuit makes 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. An ISM-Shut-Down (Input Signal Monitor) disables laser if a constant logic low is present at the input.

The system using the module must provide power supply protection that guarantees that the system power source will cease to provide power if the maximum recommended operation limit or more is detected on the +3.3 V/+5 V at the power source. The case temperature of the module must be in the temperature range given in the recommended operating limits. These limits guarantee the laser safety. dB s Signal Detect Assert Time tASS Tbd Signal Detect Deassert Time tDAS Tbd Output Low K305-C63 Voltage(4) K305-C363 VOL-VCC -1950 -1620 mV Output High K305-C63 Voltage(4) K305-C363 VOH- VCC Output Data Rise/Fall Time, 20%-80% t ,t Return Loss of Receiver ARL R This multimode Gigabit Ethernet transceiver is a Class 1 laser product.

It also assumes self biasing at the receiver data inputs (RD+/RD-) of the SerDes chip. Refer to the manufacturer data sheet for other applications. 3.3 V-Transceivers can be directly connected to SerDes-Chips using standard PECL Termination network. Value of R1 may vary as long as proper 50 termination to VEE or 100 differential is provided. The power supply filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module VCCRX/VCCTX. The transceiver contains an automatic shutdown circuit. Reset is only possible if the power is turned off, and then on again.
