DESCRIPTION
This data sheet describes the Infineon Fast Ethernet/FDDI/ATM
transceiver--part of Infineon Multistandard Transceiver Family.
It is fully compliant with the Asynchronous Transfer Mode
(ATM) OC-3 standard, the Fiber Distributed Data Interface
(FDDI) Low Cost Fiber Physical Layer Medium Dependent (LCF-
PMD) draft standard
(1)
, and the FDDI PMD standard
(2)
.
ATM was developed because of the need for multimedia appli-
cations, including real time transmission. The data rate is scal-
able and the ATM protocol is the basis of the broadband public
networks being standardized in the International Telegraph and
Telephone Consultative Committee (CCITT). ATM can also be
used in local private applications.
FDDI is a Dual Token Ring standard developed in the U.S. by the
Accredited National Standards Committee (ANSC) X3T9, within
the Technical Committee X3T9.5. It is applied to the local area
networks of stations, transferring data at 100 Mbits/s with a
125 MBaud transmission rate. LCF FDDI is specially developed
for short distance applications of up to 500 m (fiber-to-the-desk)
as compared to 2 km for backbone applications.
Fast Ethernet was developed because of the higher bandwidth
requirement in local area networking. It is based on the proven
effectiveness of millions of installed Ethernet systems.
The Infineon multimode transceiver is a single unit comprised
of a transmitter, a receiver, and an ST receptacle. This design
frees the customer from many alignment and PC board layout
concerns. The modules are designed for low cost applications.
The inputs/outputs are PECL compatible and the unit operates
from a 3.0 V to 5.5 V power supply. As an option, the data out-
put stages can be switched to static levels during absence of
light, as indicated by the Signal Detect function. It can be
directly interfaced with available chipsets.

conditions.

(I

CC3
) does not include the load drive current (Icc1). Add max.
45 mA for the three outputs. Load is 50
into VCC 2V.
2. To maintain good LED reliability, the device should not be held in the
ON state for more than the specified time. Normal operation should
be done with 50% duty cycle.
3. To achieve proper PECL output levels the 50
termination should be
done to VCC 2 V. For correct termination see the application notes.

Transmitter Electro-Optical Characteristics
Notes
1. Measured at the end of 5 meters of 62.5/125/0.275 graded index
fiber using calibrated power meter and a precision test ferrule.
Cladding modes are removed. Values valid for EOL and worst-case
temperature.
2. The input data pattern is a 12.5 MHz square wave pattern.
3. Center wavelength is defined as the midpoint between the two
50% levels of the optical spectrum of the LED.
4. Spectral width (full width, half max) is defined as the difference
between 50% levels of the optical spectrum of the LED.
5. 10% to 90% levels. Measured using the 12.5 MHz square wave
pattern with an optoelectronic measurement system (detector
and oscilloscope) having 3 dB bandwidth ranging from less than
0.1 MHz to more than 750 MHz.
6. Extinction Ratio is defined as PL/PH x 100%. Measurement system
as in Note 5.
7. Optical Power Low is the output power level when a steady state
low data pattern (FDDI Quiet Line state) is used to drive the trans-
mitter. Value valid <1 ms after input low.
8. Test method as for FDDI-PMD. Jitter values are peak-to-peak.
9. Duty Cycle Distortion is defined as 0.5 [(width of wider state) minus
(width of narrower state)]. It is measured with stream of Idle
Symbols (62.5 MHz square wave).
10.Measured with the same pattern as for FDDI-PMD.
11. Measured with the Halt Line state (12.5 MHz square wave).
Receiver Electro-Optical Characteristics
Notes
1. Pattern: Manchester coding / NRZI (no scrambling)
2. For a bit error rate (BER) of less than 1x10
E12
over a receiver eye
opening of least 1.5 ns. Measured with a 2
23
1 PRBS at 155 MBd.
3. For a BER of less than 1x10
E-12
. Measured in the center of the eye
opening with a 2
23
-1 PRBS at 155 MBd.
4. Measured at an average optical power level of 20 dBm with a 62.5
MHz square wave.
5. All jitter values are peak-to-peak. RX output jitter requirements are
not considered in the ATM standard draft. In general the same
requirements as for FDDI are met.
6. Measured at an average optical power level of 20 dBm.
7. Measured at 33 dBm average power.
8. An increase in optical power through the specified level will
cause the SIGNAL detect output to switch from a Low state to
a High state.
9. A decrease in optical power through the specified level will
cause the SIGNAL detect output to switch from a High state to
a Low state.
10. PECL compatible. Load is 50
into V
CC
2 V. Measured under DC
conditions. For dynamic measurements a tolerance of 50 mV should
be added for V

=5 V.
