v23848-h18-c56 description preliminary product information 5 2003-08-13 functional description of isfp transceiver this transceiver is designed to transmit serial data via single mode cable. figure 2 functional diagram the receiver component converts the optical serial data into lvpecl compatible electrical data (rd+ and rd?). the loss of signal (los) shows whether an optical signal is present. the transmitter converts lvpecl compatible electrical serial data (td+ and td?) into optical serial data. data lines are differentially 100 ? terminated. the transmitter contains a laser driver circui t 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 laser fault to guarantee the laser eye safety. laser driver power control limiting amp tia o/e o/e laser e/o rx coupling unit td + td ? tx disable tx fault rd ? los rd + tx coupling unit single mode fiber monitor automatic shut-down eeprom digital diagnostic monitoring interface alarm and warning flags mod-def(2) mod-def(1) file: 1354
v23848-h18-c56 description preliminary product information 6 2003-08-13 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. a low signal on txdis enables transmitter. if txdis is high or not connected the transmitter is disabled. an enhanced digital diagnostic monitoring interface (intelligent) has been incorporated into the infineon small form-factor pluggable (sfp) transceiver. this allows real time access to transceiver operating parameters, based on the sff-8472. this transceiver features internal cali bration. measurements are calibrated over operating temperature and voltage and must be interpreted as defined in sff-8472. the transceiver generates this diagnostic data by digitization of internal analog signals monitored by a new diagnostic integrated circuit (ic). this diagnostic ic has inbuilt sensors to include alarm and warning thresholds. these threshold values are set during device manufacture and therefore allow the user to determine when a particular value is outside of its operating range. alarm and warning flags are given. alarm flags indicate conditions likely to be associated with an inoperational link and cause for immediate action. warning flags indicate conditions outside the normally guaranteed bounds but not necessarily causes of immediate link failures. these enhanced features are in addition to the existing sfp features provided by the manufacturer i.e. serial number and other vendor specific data. the serial id interface defines a 256 byte memory map in eeprom, accessible over a 2 wire, serial interface at the 8 bit address 1010000x (a0h). the digital diagnostic monitoring interface makes use of the 8 bit address 1010001x (a2h), so the originally defined serial id memory map remains unchanged and is therefore backward compatible. digital diagnostic monitoring parameters parameter accuracy sff-8472 accuracy actual tx optical power 3 db 2 db rx optical power 3 db 3 db bias current 10% 10% power supply voltage 3% 3% transceiver temperature 3c 3c

v23848-h18-c56 application notes preliminary product information 16 2003-08-13 application notes emi recommendations to avoid electromagnetic radiation exceeding the required limits set by the standards, please take note of the following recommendations. when gigabit switching components are found on a pcb (e.g. multiplexer, serializer-deserializer, clock data recovery, etc.), any opening of the chassis may leak radiation; this may also occur at chassis slots other than that of the device itself. thus every mechanical opening or aperture should be as small as feasible and its length carefully considered. on the board itself, every data connection should be an impedance matched line (e.g. strip line or coplanar strip line). data (d) and data-not (dn) should be routed symmetrically. vias should be avoided. where internal termination inside an ic or a transceiver is not present, a line terminating resistor must be provided. the decision of how best to establish a ground depends on many boundary conditions. this decision may turn out to be critical for achieving lowest emi performance. at rf frequencies the ground plane will always carry some amount of rf noise. thus the ground and v cc planes are often major radiators inside an enclosure. as a general rule, for small systems such as pci cards placed inside poorly shielded enclosures, the common ground scheme has often proven to be most effective in reducing rf emissions. in a common ground scheme, the pci card becomes more equipotential with the chassis ground. as a result, the overall radiation will decrease. in a common ground scheme, it is strongly recommended to provide a proper contact between signal ground and chassis ground at every location where possible. this concept is designed to avoid hotspots which are places of highest radiation, caused when only a few connections between chassis and signal grounds exist. compensation currents would concentrate at these connections, causing radiation. however, as signal ground may be the main cause for parasitic radiation, connecting chassis ground and signal ground at the wrong place may result in enhanced rf emissions. for example, connecting chassis ground and signal ground at a front panel/bezel/chassis by means of a fiber optic transceiver/cage may result in a large amount of radiation especially where combined with an inadequate number of grounding points between signal ground and chassis ground. thus the transceiver becomes a single contact point increasing radiation emissions. even a capacitive coupling between signal ground and chassis ground may be harmful if it is too close to an opening or an aperture. for a number of systems, enforcing a strict separation of signal ground from chassis ground may be advantageous, providing the housing does not present any slots or other discontinuities. this separate ground concept seems to be more suitable in large systems where appropriate shielding measures have also been implemented. the return path of rf current must also be considered. thus a split ground plane between tx and rx paths may result in severe emi problems.
v23848-h18-c56 application notes preliminary product information 17 2003-08-13 the bezel opening for a transceiver should be sized so that all contact springs of the transceiver cage make good electrical contact with the face plate. please consider that the pcb may behave like a dielectric waveguide. with a dielectric constant of 4, the wavelength of the harmonics inside the pcb will be half of that in free space. thus even the smallest pcbs may have unexpected resonances. large systems can have many openings in the front panel for sfp transceivers. in typical applications, not all of these ports will hold transceivers; some may be intentionally left empty. these empty slots can emit significant amounts of radiation. thus it is strongly recommended that empty ports be plugged with an emi plug as shown in figure 5 . infineon offers an emi/dust plug, p/n v23818-s5-b1. infineon proposes figure 5 cage: infineon technologies part number: v23838-s5-n1 cage emi/dust plug: infineon technologies part number: v23818-s5-b1 host board connector: tyco electronics part number: 1367073-1 file: 1521 cage isfp host board connector host board dust plug cage emi/dust plug
