Description
The AFBR-5903Z family of transceivers from Avago Tech-
nologies provide the system designer with products
to implement a range of FDDI and ATM (Asynchronous
Transfer Mode) designs at the 100 Mb/s-125 MBd rate.
The transceivers are all supplied in the new industry
standard 2 x 5 DIP style with a MT-RJ ber connector
interface.
FDDI PMD, ATM and Fast Ethernet 2 km Backbone Links
The AFBR-5903Z is a 1300 nm product with optical per-
formance compliant with the FDDI PMD standard. The
FDDI PMD standard is ISO/IEC 9314-3: 1990 and ANSI
X3.166 - 1990.
These transceivers for 2 km multimode ber backbones
are supplied in the small 2 x 5 MT-RJ package style for
those designers who want to avoid the larger MIC/R
(Media Interface Connector/Receptacle) dened in the
FDDI PMD standard.
Avago Technologies also provides several other FDDI
products compliant with the PMD and SM-PMD standards.
These products are available with MIC/R, ST
©
, SC and FC
connector styles. They are available in the 1 x 9, 1 x 13 and
2 x 11 transceiver and 16 pin transmitter/receiver pack-
age styles for those designs that require these alternate
congurations.
The AFBR-5903Z is also useful for both ATM 100 Mb/s
interfaces and Fast Ethernet 100 Base-FX interfaces. The
ATM Forum User-Network Interface (UNI) Standard, Version
3.0, denes the Physical Layer for 100 Mb/s Multimode
Fiber Interface for ATM in Section 2.3 to be the FDDI PMD
Standard. Likewise, the Fast Ethernet Alliance denes the
Physical Layer for 100 Base-FX for Fast Ethernet to be the
FDDI PMD Standard.
ATM applications for physical layers other than 100
Mb/s Multimode Fiber Interface are supported by
Avago Technologies. Products are available for both
the single-mode and the multimode ber SONET OC-3c
(STS-3c), SDH (STM-1) ATM interfaces and the 155 Mb/s-
194 MBd multimode ber ATM interface as specied
in the ATM Forum UNI.

tive for information on these alternative FDDI and ATM
products.

Transmitter Sections
The transmitter section of the AFBR-5903Z utilizes a 1300
nm Surface Emitting InGaAsP LED. This LED is packaged
in the optical subassembly portion of the transmitter
section. It is driven by a custom silicon IC which converts
dierential PECL logic signals, ECL referenced (shifted) to
a +3.3 V supply, into an analog LED drive current.
Receiver Sections
The receiver section of the AFBR-5903Z utilizes an InGaAs
PIN photodiode coupled to a custom silicon transimped-
ance preamplier IC. It is packaged in the optical sub-
assembly portion of the receiver.
This PIN/preamplier combination is coupled to a custom
quantizer IC which provides the nal pulse shaping for
the logic output and the Signal Detect function. The Data
output is dierential. The Signal Detect output is single-
ended. Both Data and Signal Detect outputs are PECL
compatible, ECL referenced (shifted) to a +3.3 V power
supply. The receiver outputs, Data Out and Data Out Bar,
are squelched at Signal Detect Deassert. That is, when the
light input power decreases to a typical -38 dBm or less,
the Signal Detect Deasserts, i.e. the Signal Detect output
goes to a PECL low state. This forces the receiver outputs,
Data Out and Data Out Bar to go to steady PECL levels
High and Low respectively.
Package
The overall package concept for the Avago Technologies
transceiver consists of the following basic elements; two
optical subassemblies, an electrical subassembly and the
housing as illustrated in Figure 1.
The package outline drawing and pin out are shown in Figures
2 and 3. The details of this package outline and pin out are
compliant with the multisource denition of the 2 x 5 DIP.
The low prole of the Avago Technologies transceiver design
complies with the maximum height allowed for the MT-RJ
connector over the entire length of the package.
The optical subassemblies utilize a high-volume assembly
process together with low-cost lens elements which result
in a cost-eective building block.
The electrical subassembly consists of a high volume mul-
tilayer printed circuit board on which the IC and various
surface-mounted passive circuit elements are attached.
The receiver section includes an internal shield for the elec-
trical and optical subassemblies to ensure high immunity to
external EMIelds.
The outer housing is electrically conductive and is at receiver
signal ground potential. The MT-RJ port is molded of lled
nonconductive plastic to provide mechanical strength
and electrical isolation. The solder posts of the Avago
Technologies design are isolated from the internal circuit
of the transceiver.
The transceiver is attached to a printed circuit board with
the ten signal pins and the two solder posts which exit
the bottom of the housing. The two solder posts provide
the primary mechanical strength to withstand the loads
imposed on the transceiver by mating with the MT-RJ
connectored ber cables.
