Recommended Handling Precautions
Avago Technologies recommends that normal static pre-
cautions be taken in the handling and assembly of these
transceivers to prevent damage which may be induced
by electrostatic discharge (ESD). The AFBR-5800Z series
of transceivers meet MIL-STD-883C Method 3015.4 Class
2 products.
Care should be used to avoid shorting the receiver data or
signal detect outputs directly to ground without proper
current limiting impedance.
Solder and Wash Process Compatibility
The transceivers are delivered with protective process
plugs inserted into the duplex SC or duplex ST connector
receptacle. This process plug protects the optical subas-
semblies during wave solder and aqueous wash process-
ing and acts as a dust cover during shipping.
These transceivers are compat ible with either industry
standard wave or hand solder processes.

NOTES:
THE SPLIT-LOAD TERMINATIONS FOR ECL SIGNALS NEED TO BE LOCATED AT THE INPUT
R1 = R4 = R6 = R8 = R10 = 130 OHMS FOR +5.0 V OPERATION, 82 OHMS FOR +3.3 V OPERATION.
R2 = R3 = R5 = R7 = R9 = 82 OHMS FOR +5.0 V OPERATION, 130 OHMS FOR +3.3 V OPERATION.
C1 = C2 = C3 = C5 = C6 = 0.1 µF.
C4 = 10 µF.
L1 = L2 = 1 µH COIL OR FERRITE INDUCTOR.

Shipping Container
The transceiver is packaged in a shipping container de-
signed to protect it from mechanical and ESD damage
during shipment or storage.
Board Layout - Decoupling Circuit and Ground Planes
It is important to take care in the layout of your circuit
board to achieve optimum perform ance from these trans-
ceivers. Figure 7 provides a good example of a schematic
for a power supply decoupling circuit that works well
with these parts. It is further recommended that a con-
tiguous ground plane be provided in the circuit board di-
rectly under the transceiver to provide a low inductance
ground for signal return current. This recommen da tion is
in keeping with good high frequency board layout prac-
tices.
