V23806-A8-C1 Datasheet, PDF (2/3 Pages) Infineon Technologies AG – Multimode 1300 nm LED Fast Ethernet/FDDI/ATM 10 dB 155 MBd 1x9 Transceiver
The data rate is scalable and the ATM protocol is the basis of
the broadband public networks being standardized in the Inter-
national 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 SC receptacle. This design
frees the customer from many alignment and PC board layout
concerns. The modules are designed for low cost applications.

Notes
1. For VCC–VEE (min., max.). 50% duty cycle. The supply current
(ICC2+ICC3) does not include the load drive current (Icc1). Add max.
45 mA for the three outputs. Load is 50 Ω 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 Ω termination should be
done to VCC –2 V. For correct termination see the application notes.

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. Test method as for FDDI-PMD. Jitter values are peak-to-peak.
8. 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).
9. Measured with the same pattern as for FDDI-PMD.
10.Measured with the Halt Line state (12.5 MHz square wave).
