Electrostatic Discharge
Caution: This device is susceptible to damage as
a result of electrostatic discharge (ESD).
Take proper precautions during both
handling and testing. Follow
EIA
Stan-
dard
EIA
-625.
Although protection circuitry is designed into the
device, take proper precautions to avoid exposure to
ESD.
Agere Systems employs a human-body model (HBM)
for ESD-susceptibility testing and protection-design
evaluation. ESD voltage thresholds are dependent on
the critical parameters used to define the model. A
standard HBM (resistance = 1.5 k
, capacitance =
100 pF) is widely used and, therefore, can be used for
comparison purposes. The HBM ESD threshold estab-
lished for the 1430G5 transceiver is
1000 V.
Application Information
The 1430 receiver section is a highly sensitive fiber-
optic receiver. Although the data outputs are digital
logic levels (LVPECL), the device should be thought of
as an analog component. When laying out system
application boards, the 1430 transceiver should receive
the same type of consideration one would give to a
sensitive analog component.
Printed-Wiring Board Layout Considerations
A fiber-optic receiver employs a very high gain, wide
bandwidth transimpedance amplifier. This amplifier
detects and amplifies signals that are only tens of nA in
amplitude when the receiver is operating near its sensi-
tivity limit. Any unwanted signal currents that couple
into the receiver circuitry cause a decrease in the
receiver's sensitivity and can also degrade the perfor-
mance of the receiver's signal detect (SD) circuit. To
minimize the coupling of unwanted noise into the
receiver, careful attention must be given to the printed-
wiring board.
At a minimum, a double-sided printed-wiring board
(PWB) with a large component-side ground plane
beneath the transceiver must be used. In applications
that include many other high-speed devices, a multi-
layer PWB is highly recommended. This permits the
placement of power and ground on separate layers,
which allows them to be isolated from the signal lines.
Multilayer construction also permits the routing of sen-
sitive signal traces away from high-level, high-speed
signal lines. To minimize the possibility of coupling
noise into the receiver section, high-level, high-speed
signals such as transmitter inputs and clock lines
should be routed as far away as possible from the
receiver pins.

Application Information
(continued)
Noise that couples into the receiver through the power
supply pins can also degrade performance. It is
recommended that the pi filter, shown in Figure 3, be
used for both the transmitter and receiver power
supplies.
Data, Clock, and Signal Detect Outputs
The data, clock, and signal detect outputs of the 1430
transceiver are driven by open-emitter NPN transistors,
which have an output impedance of approximately 7
.
Each output can provide approximately 50 mA maxi-
mum current to a 50
load terminated to V
CC
2.0 V.
Due to the high switching speeds of ECL outputs,
transmission line design must be used to interconnect
components. To ensure optimum signal fidelity, both
data outputs (RD+/RD) and clock outputs
(CLK+/CLK) should be terminated identically. The sig-
nal lines connecting the data clock outputs to the next
device should be equal in length and have matched
impedances. Controlled impedance stripline or micro-
strip construction must be used to preserve the quality
of the signal into the next component and to minimize
reflections back into the receiver, which could degrade
its performance. Excessive ringing due to reflections
caused by improperly terminated signal lines makes it
difficult for the component receiving these signals to
decipher the proper logic levels and can cause transi-
tions to occur where none were intended. Also, by min-
imizing high-frequency ringing, possible EMI problems
can be avoided.
The signal-detect output is LVTTL logic. A logic low at
this output indicates that the optical signal into the
receiver has been interrupted or that the light level has
fallen below the minimum signal detect threshold. This
output should not be used as an error rate indicator,
since its switching threshold is determined only by the
magnitude of the incoming optical signal.
Transceiver Processing
The transceiver and plug can withstand normal wave
soldering and aqueous spray cleaning processes.
However, the transceiver is not hermetic, and should
not be subjected to immersion in cleaning solvents.
The transceiver case should not be exposed to temper-
atures in excess of 125
C. The fiber pigtail cannot
exceed 85
C. The transceiver pins can be wave sol-
dered at 250
C for up to 10 seconds.
