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 connec-
tor receptacle. This process plug protects the optical
subassemblies during wave solder and aqueous wash
processing and acts as a dust cover during shipping.
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.

These transceivers are compatible with either industry
standard wave or hand solder processes.
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 performance from these
transceivers. Figure  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 contiguous ground plane be provided in the
circuit board directly under the transceiver to provide
a low inductance ground for signal return current. This
recommendation is in keeping with good high frequen-
cy board layout practices.
