DESCRIPTION
The Infineon single mode transceiver is based on the Physical
Medium Depend (PMD) sublayer and baseband medium, type
1000BASE-LX (Long Wavelength Laser) (IEEE 802.5) and com-
plies with the Fibre Channel Physical and Signaling Interface
(FC-PH), ANSI XSI TT Fibre Channel Physical Standard Class
100-SM-LL-I, latest Revision.
The appropriate fiber optic cable is 9 µm (mode field diameter)
single mode fiber (up to 10 km) with Duplex SC connector.
The Infineon single 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 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.
This transceiver operates at 1.0625 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.
Functional Description
This transceiver is designed to transmit serial data via single
mode or multimode cable.

*DC/DC Version only
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
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.
This version contains an Input Signal Monitor (ISM) which
switches off the transceiver if a continuous low level is applied
at Data Input.
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 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.

APPLICATION NOTE
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).
