AFBR-5803Z/5803TZ/5803AZ/5803ATZ
FDDI, 100 Mb/s ATM, and Fast Ethernet Transceivers in
Low-Cost 1 × 9 Package Style
Data Sheet
Description
The AFBR-5800Z family of transceivers from Broadcom®
provide the system designer with products to implement a
range of Fast Ethernet, FDDI, and Asynchronous Transfer Mode
(ATM) designs at the 100 Mb/s-125 MBd rate.
The transceivers are all supplied in the industry standard 1 × 9
SIP package style with either a duplex SC or a duplex ST*
1
connector interface.
Features
FDDI PMD, ATM and Fast Ethernet 2-km
Backbone Links
The AFBR-5803Z/5803TZ are 1300-nm products with optical
performance 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 fiber backbones are
supplied in the small 1 × 9 duplex SC or ST package style.
The AFBR-5803Z/5803TZ is useful for both ATM 100 Mb/s
interfaces and Fast Ethernet 100BASE-FX interfaces. The ATM
Forum User-Network Interface (UNI) Standard, Version 3.0,
defines 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 defines the Physical Layer
for 100BASE-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 Broadcom.
Products are available for both the single mode and the
multi-mode fiber SONET OC-3c (STS-3c) ATM interfaces and the
155 Mb/s-194 MBd multi-mode fiber ATM interface as specified
in the ATM Forum UNI.
Contact your Broadcom sales representative for information on
these alternative Fast Ethernet, FDDI, and ATM products.

Data Sheet
Transmitter Sections
The transmitter section of the AFBR-5803Z and AFBR-5805Z
series usee 1300-nm surface-emitting InGaAsP LEDs. These
LEDs are packaged in the optical subassembly portion of the
transmitter section. They are driven by a custom silicon IC,
which converts differential PECL logic signals, ECL referenced
(shifted) to a +3.3V or +5V supply, into an analog LED drive
current.
The package outline drawings and pin out are shown in
Figure 3, Figure 4,
and
Figure 5.
The details of this package
outline and pin out are compliant with the multi-source
definition of the 1 × 9 SIP. The low profile of the Broadcom
transceiver design complies with the maximum height allowed
for the duplex SC connector over the entire length of the
package.
The optical subassemblies use a high-volume assembly
process together with low-cost lens elements that result in a
cost effective building block.
The electrical subassembly consists of a high-volume
multilayer printed circuit board on which the IC chips and
various surface-mounted passive circuit elements are attached.
The package includes internal shields for the electrical and
optical subassemblies to ensure low EMI emissions and high
immunity to external EMI fields.
The outer housing including the duplex SC connector
receptacle or the duplex ST ports is molded of filled
nonconductive plastic to provide mechanical strength and
electrical isolation. The solder posts of the Broadcom design
are isolated from the circuit design of the transceiver and do
not require connection to a ground plane on the circuit board.
The transceiver is attached to a printed circuit board with the
nine signal pins and the two solder posts that 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 duplex or simplex SC or ST
connectored fiber cables.
Receiver Sections
The receiver sections of the AFBR-5803Z and AFBR-5805Z
series use InGaAs PIN photodiodes coupled to a custom silicon
transimpedance preamplifier IC. These are packaged in the
optical subassembly portion of the receiver.
These PIN/preamplifier combinations are coupled to a custom
quantizer IC that provides the final pulse shaping for the logic
output and the Signal Detect function. The data output is
differential. The signal detect output is single-ended. Both data
and signal detect outputs are PECL compatible, ECL referenced
(shifted) to a +3.3V or +5V power supply.
Package
The overall package concept for the Broadcom transceivers
consists of the following basic elements: two optical
subassemblies, an electrical subassembly, and the housing as
illustrated in
Figure 1
and
Figure 2.
