Description
The 1417G5 and 1417H5 transceivers are high-
speed, cost-effective optical transceivers that are
compliant with the International Telecommunication
Union Telecommunication (ITU-T) G.957 specifica-
tions for use in ATM, SONET, and SDH applications.
The 1417G5 operates at the OC-3/STM-1 rate of
155 Mbits/s, and the 1417H5 operates at the OC-12/
STM-4 rate of 622 Mbits/s. The transceiver features
Agere Systems high-reliability optics and is pack-
aged in a narrow-width plastic housing with an LC
duplex receptacle. This receptacle fits into an RJ-45
form factor outline. The 20-pin package and pinout
conform to a multisource transceiver agreement.
The transmitter features differential PECL logic level
data inputs and a LVTTL logic level disable input. The
receiver features differential PECL logic level data
and clock outputs and a LVTTL logic level signal-
detect output.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.

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 depen-
dent on the critical parameters used to define the
model. A standard HBM (resistance = 1.5 k, capaci-
tance = 100 pF) is widely used and, therefore, can be
used for comparison purposes. The HBM ESD thresh-
old established for the 1417G5 and 1417H5 transceiv-
ers is ±1000 V.
Application Information
The 1417 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 1417 transceiver should receive the
same type of consideration one would give to a sensi-
tive analog component.
Agere Systems Inc.
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.
