failed transmitter).
Functional Data I/O
Avago’s HFBR-5720AL/ALP fiber-
optic transceiver is designed to
accept industry standard
differential signals. In order to
reduce the number of passive
components required on the
customer’s board, Avago has
included the functionality of the
transmitter bias resistors and
coupling capacitors within the
fiber optic module. The
transceiver is compatible with an
“AC-coupled” configuration and is
internally terminated. Figure 1
depicts the functional diagram of
the HFBR-5720AL/ALP.
Caution should be taken for the
proper interconnection between
the supporting Physical Layer
integrated circuits and the HFBR-
5720AL/ALP. Figure 4 illustrates
the recommended interface
circuit.
Several MSA compliant control
data signals are implemented in
the module and are depicted in
Figure 6.

Application Support
Evaluation Kit
To help you in your preliminary
transceiver evaluation, Avago
offers a 2.125 GBd Fibre Channel
evaluation board. This board will
allow testing of the fiber-optic
VCSEL transceiver. Please
contact your local field sales
representative for availability and
ordering details.
Reference Designs
Reference designs for the HFBR-
5720AL/ALP fiber-optic
transceiver and the HDMP-2630/
2631 physical layer IC are
available to assist the equipment
designer. Figure 4 depicts a
typical application configuration,
while Figure 5 depicts the MSA
power supply filter circuit design.
All artwork is available at the
Avago Website. Please contact
your local field sales engineer for
more information regarding
application tools.

Regulatory Compliance
performance. The overall
equipment design will determine
the certification level. The
transceiver performance is
offered as a figure of merit to
assist the designer.
Electrostatic Discharge (ESD)
There are two conditions in which
immunity to ESD damage is
important. Table 1 documents
our immunity to both of these
conditions. The first condition is
during handling of the transceiver
prior to insertion into the
transceiver port. To protect the
transceiver, it is important to use
normal ESD handling
precautions. These precautions
include using grounded wrist
straps, work benches, and floor
mats in ESD controlled areas.
The ESD sensitivity of the HFBR-
5720AL/ALP is compatible with
typical industry production
environments. The second
condition is static discharges to
the exterior of the host
equipment chassis after
installation. To the extent that the
duplex LC optical interface is
exposed to the outside of the host
equipment chassis, it may be
subject to system-level ESD
requirements. The ESD
performance of the HFBR-
5720AL/ALP exceeds typical
industry standards.
