Figure 3. Block Diagram
Package
The overall package concept for these devices consists
of the following basic elements; two optical subassem-
blies, a electrical subassembly and the housing as illus-
trated in the block diagram in Figure 3.
The package outline drawing and pin out are shown in
Figures 4 and 5. 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 LC connector over the entire length of
the package.
The electrical subassembly consists of high volume
multilayer printed circuit board on which the IC and
various surface-mounted passive circuit elements are
attached.
The optical subassemblies are attached to the electrical
subassembly. These two units are then tted within the
outer housing of the transceiver. The housing is then
encased with a metal EMI protective shield.
The electrical subassemby carries the signal pins that
exit from the bottom of the transceiver. The solder
posts are designed to provide the mechanical strength
required to withstand the loads imposed on the trans-
ceiver by mating with the LC connectored ber cables.
Although they are not connected electrically to the
transceiver, it is recommended to connect them to
chassis ground.

Pin Descriptions:
Pin 1 Receiver Signal Ground V
EE
RX:
Directly connect this pin to the receiver ground plane.
Pin 2 Receiver Power Supply V
CC
RX:
Provide +3.3 V dc via the recommended receiver
power supply lter circuit. Locate the power supply
lter circuit as close as possible to the V
CC
RX pin. Note:
the lter circuit should not cause V
CC
to drop below
minimum specication.
Pin 3 Signal Detect SD:
Normal optical input levels to the receiver result in a
logic “1” output.
Low optical input levels to the receiver result in a logic
“0” output.
This Signal Detect output can be used to drive a LVPECL
input on an upstream circuit, such as Signal Detect
input or Loss of Signal-bar.
Pin 4 Receiver Data Out Bar RD-:
No internal terminations are provided. See recommend-
ed circuit schematic.
Pin 5 Receiver Data Out RD+:
No internal terminations are provided. See recommend-
ed circuit schematic.
Pin 6 Transmitter Power Supply
V
CC
TX:
Provide +3.3 V dc via the recommended transmitter
power supply lter circuit. Locate the power supply
lter circuit as close as possible to the V

TX pin.
Pin 7 Transmitter Signal Ground
V
EE
TX:
Directly connect these pins to the transmitter signal
ground plane.
Pin 8 Transmitter Disable T
DIS
:
Optional feature, connect this pin to +3.3 V TTL logic
high “1” to disable module. To enable module connect
to TTL logic low “0”.
Pin 9 Transmitter Data In TD+:
No internal terminations are provided. See recommend-
ed circuit schematic.
Pin 10 Transmitter Data In Bar TD-:
No internal terminations are provided. See recommend-
ed circuit schematic.
Mounting Studs/Solder Posts
The two mounting studs are provided for transceiv-
er mechanical attachment to the circuit board. It is
recommended that the holes in the circuit board be
connected to chassis ground.
