V23826-K305-Cxx/Cxxx
Description Description The Infineon multimode transceiver is based on the Physical Medium Depend (PMD) sublayer and baseband medium, type 1000-Base-SX (Short 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 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, 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.

The receiver component converts the optical serial data into PECL compatible electrical data (RD+ and RD-). The Signal Detect (SD, active high) shows whether an optical signal is present. The transmitter converts electrical PECL compatible serial data (TD+ and TD-) into optical serial data. The following versions are available: 1 AC/DC transceiver: Tx is AC coupled. Differential 100 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 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 load. Signal Detect is PECL compatible.

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. Regulatory Compliance Feature Standard Comments Class 1 (> 1000 V) HBM Class 1C Discharges of 15 kV with an air discharge probe on the receptacle cause no damage. With a field strength of 3 V/m, noise frequency ranges from 10 MHz to 1 GHz. No effect on transceiver performance between the specification limits. Noise frequency range: 30 MHz to 18 GHz; Margins depend on PCB layout and chassis design.

An increase in optical power above the specified level will cause the Signal Detect output to switch from a low state to a high state. A decrease in optical power below the specified level will cause the Signal Detect to change from a high state to a low state. DC/DC, AC/DC for data. DC/DC, AC/DC, AC/AC PECL for SD. PECL compatible. Load is 50 into VCC-2 V for data, 500 to VEE for Signal Detect. Measured under DC conditions. For dynamic measurements a tolerance of 50 mV should be added. VCC = 3.3 V/5 V. TAMB = 25C.

Application Notes Application Notes Gigabit transceivers and matching circuits are high frequency components and shall be terminated as recommended in the application notes for proper EMI performance. 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).

Figure 5 This Application Note assumes Fiber Optic Transceivers using 5 V power supply and SerDes Chips using 3.3 V power supply. 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. (VCCTx switched below VTH). Application Board available on request.
