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.
Lucent 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 pur-
poses. The HBM ESD threshold established 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 (PECL), the device should be thought of as
an analog component. When laying out system appli-
cation boards, the 1430 transceiver should receive the
same type of consideration one would give to a sensi-
tive 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.
