Transmitter Section
The transmitter section of the HFBR-5963L utilizes a 1300
nm InGaAsP LED. This LED is packaged in the optical sub-
assembly portion of the transmitter section. It is driven
by a custom silicon IC which converts differential PECL
logic signals, ECL referenced (shifted) to a +3.3 V supply,
into an analog LED drive current.
Receiver Section
The receiver section of the HFBR-5963L utilizes an InGaAs
PIN photodiode coupled to a custom silicon transimped-
ance preamplifier IC. It is packaged in the optical subas-
sembly portion of the receiver.
This PIN/preamplifier combination is coupled to a custom
quantizer IC which provides the final pulse shaping for
the logic output and the signal detect function. The data
output is differential. The data output is PECL compat-
ible, ECL referenced (shifted) to a +3.3 V power supply.
The receiver outputs, data output and data out bar, are
squelched at signal detect deassert. The signal detect
output is single ended. The signal detect circuit works by
sensing the level of the received signal and comparing
this level to a reference. The SD output is +3.3 V TTL.
Package
The overall package concept for the Avago Technologies
transceiver consists of three basic elements; the two op-
tical subassemblies, an electrical subassembly, and the
housing as illustrated in the block diagram in Figure 1.
The package outline drawing and pin out are shown in

Figures 2 and 5. The details of this package outline and
pin out are compliant with the multisource definition of
the 2 x 5 DIP. The low profile of the Avago Technologies
transceiver design complies with the maximum height
allowed for the LC connector over the entire length of
the package.
The optical subassemblies utilize a high-volume assem-
bly process together with low-cost lens elements which
result in a cost- effective building block.
The electrical subassembly consists of a high volume mul-
tilayer printed circuit board on which the ICs and various
surface-mounted passive circuit elements are attached.
The receiver section includes an internal shield for the
electrical and optical subassemblies to ensure high im-
munity to external EMI fields.
The outer housing including the LC ports is molded
of filled nonconductive plastic to provide mechanical
strength. The solder posts of the Avago Technologies
design are isolated from the internal circuit of the trans-
ceiver.
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 LC con-
nector fiber cables.
