V23809-C8-C10 Datasheet, PDF (2/6 Pages) Infineon Technologies AG – Multimode 1300 nm LED Fast Ethernet/FDDI/ATM 170 MBd 1x9 Transceiver

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 SC 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.

Notes
1. For V_CC–V_EE (min., max.). 50% duty cycle. The supply current
(I_CC2+I_CC3) does not include the load drive current (Icc1). Add max.
45 mA for the three outputs. Load is 50 Ω into V_CC –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 V_CC –2 V. For correct termination see the application notes.
