1. Standard version
DESCRIPTIONThe 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 com-
plies 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 µm or 50 µm multi-
mode 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 Ether-
net, and Fibre Channel applications. It can be used as the net-
work 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 Volt or 3.3 Volt). The full differential
data inputs and outputs are PECL compatible.
Operating range each optical fiber type at 1.0625 GBd
Functional DescriptionThis transceiver is designed to transmit serial data via multi-
mode cable.
Functional DiagramThe 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 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 Ω 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 Ω 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 Ω load. Signal
Detect is PECL compatible.
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 out-
put 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 thereset 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 isinactive.
TECHNICAL DATAThe electro-optical characteristics described in the following
tables are only valid for use under the recommended operating
conditions.
Recommended Operating ConditionsNotes
1. For VCC–VEE (min., max.) 50% duty cycle. The supply current does
not include the load drive current of the receiver output. Add. max.
45 mA for the three outputs. Load is 50 Ω to VCC–2 V.Version C63: Low > 1.2 V; high < VCC–0.8 V
Version C363: Low > 1.2 V; high < VCC
ransmitter Electro-Optical CharacteristicsNotes. Into multimode fiber, 62.5 µm or 50 µm diameter.
2. Laser power is shut down if power supply is below VTH and
switched on if power supply is above VTH.
Receiver Electro-Optical CharacteristicsNotes
1. Minimum average optical power at which the BER is less than
1x10E-12 or lower. Measured with a 27-1 NRZ PRBS and ER=9 dB.
Output of multimode fiber 65 µm or 50 µm diameter.
2. 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.
3. A decrease in optical power below the specified level will cause the
SIGNAL DETECT to change from a High state to a Low state.
4. DC/DC, AC/DC for data;
DC/DC, AC/DC, AC/AC PECL for SD
PECL compatible. Load is 50 Ω into VCC–2 V for data, 500 Ω to V((
for Signal Detect. Measured under DC conditions. For dynamic mea-
surements a tolerance of 50 mV should be added. VCC = 3.3 V/5 V. AMB = 25°C.Max. output current high: –0.4 mA (drive current)
low: +2.0 mA (sink current)AC/AC for data. Load 50 Ω to GND or 100 Ω differential. For dynamic
measurement a tolerance of 50 mV should be added.

Regulatory Compliance
EYE SAFETYThis laser based single mode transceiver is a Class 1 product. It
complies with IEC 60825-1 and FDA 21 CFR 1040.10 and
To meet laser safety requirements the transceiver shall be oper-
ated within the Absolute Maximum Ratings.
Caution
All adjustments have been made at the factory prior to ship-
ment 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 modifica-
tion 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)).

Laser Emission
APPLICATION NOTEGigabit 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).
APPLICATION NOTE
Multimode 850nm Gigabit Ethernet/Fibre Channel 1x9 Transceiver, DC/DC VersionThis 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 con-
nected to SerDes-Chips using standard PECL Termination
network.
Value of R1 may vary as long as proper 50 Ω termination to VEE
or 100 Ω 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. CCTx switched below VTH).
