In order to get proper functionality, a recommended circuit is provided in above recommended circuit schematic. When designing the circuit
interface, there are a few fundamental guidelines to follow.
(1) The differential data lines should be treated as 50
Micro strip or strip line transmission lines. This will help to minimize the parasitic inductance
and capacitance effects. Locate termination at the received signal end of the transmission line. The length of these lines should be kept short and of
equal length.
(2) For the high speed signal lines, differential signals should be used, not single-ended signals, and these differential signals need to be loaded
symmetrically to prevent unbalanced currents which will cause distortion in the signal.
(3) Multi layer plane PCB is best for distribution of
V
CC
, returning ground currents, forming transmission lines and shielding, Also, it is important to
suppress noise from influencing the fiber-optic transceiver performance, especially the receiver circuit.
(4) A separate proper power supply filter circuits shown in Figure for the transmitter and receiver sections. These filter circuits suppress V
CC
noise over
a broad frequency range, this prevents receiver sensitivity degradation due to
V
CC
noise.
(5) Surface-mount components are recommended. Use ceramic bypass capacitors for the 0.1
μ
F capacitors and a surface-mount coil inductor for 1
μ
H
inductor. Ferrite beads can be used to replace the coil inductors when using quieter
V
CC
supplies, but a coil inductor is recommended over a ferrite
bead. All power supply components need to be placed physically next to the
V
CC
pins of the receiver and transmitter.
(6) Use a good, uniform ground plane with a minimum number of holes to provide a low-inductance ground current return for the power supply currents.
