Description

The 1417G4A and 1417H4A 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 1417G4A operates at the OC-3/STM-1 rate of
155 Mbits/s, and the 1417H4A operates at the
OC-12/STM-4 rate of 622 Mbits/s. The transceivers
feature Agere Systems' high-reliability optics and are
packaged in a narrow-width plastic housing with an
LC duplex receptacle. This receptacle fits into an RJ-
45 form factor outline. The 10-pin package and
pinout conform to a multisource transceiver agree-
ment.

The transmitter features differential PECL logic level
data inputs and a TTL logic level disable input. The
receiver features differential PECL logic level data
and a PECL logic level signal-detect output for the
1417G4A, and a TTL logic level signal-detect output
for the 1417H4A.

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 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 1417G4A and 1417H4A transceivers 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.

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 layout.

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.

Noise that couples into the receiver through the power
supply pins can also degrade performance. It is recom-
mended that the pi filter, shown in Figure 2, be used for
both the transmitter and receiver power supplies.

Data and Signal Detect Outputs

The data and signal detect outputs of the 1417 trans-
ceiver 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

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) should be terminated identi-
cally. The signal lines connecting the data outputs to
the next device should be equal in length and have
matched impedances. Controlled impedance stripline
or microstrip 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 transitions to occur where none were
intended. Also, by minimizing high-frequency ringing,
possible EMI problems can be avoided.

The signal-detect output is positive ECL (PECL) logic
for the 1417G4A and TTL for the 1417H4A. 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

When the process plug is placed in the transceiver's optical port, 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 temperatures in
excess of 125 °C. The transceiver pins can be wave soldered at 250 °C for up to 10 seconds. The process plug
should only be used once. After removing the process plug from the transceiver, it must not be used again as a pro-
cess plug; however, if it has not been contaminated, it can be reused as a dust cover.
