Description

The 1417K4A transceiv er is a high-speed, cost-eff ec-

tive optical transceiver intended for 2.488 Gbits/s

shelf-to-shelf optical interconnect applications as well

as SONET SR OC-48 and SDH I-16. The transceiv er

features proven Agere Systems’ optics and is pack-

aged in a narrow-width plastic housing with an LC

duplex receptacle. The receptacle fits into an RJ-45

form factor outline. The 10-pin package pinout con-

forms to a multisource transceiver agreement.

The transmitter f eatures the ability to interface to both

LVPECL and CML differential logic level data inputs.

It also features a TTL logic level disable input. The

receiver features differential CML logic level outputs

and a TTL 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 pr ecautions 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 kΩ, capacitance =

100 pF) is widely used and, therefore , can be used for

comparison purposes. The HBM ESD threshold estab-

lished for the 1417K4A transceiver is ±1000 V.

Application Information

The 1417 receiver section is a highly sensitive fiber-

optic receiver. Although the data outputs are digital

logic levels (CML), 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-Wi ring 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 man y other high-speed devices, a multi-

layer PWB is highly recommended. This permits the

placement of power and ground on separate la yers,

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 a way 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 a pi filter, shown in Figure 3, be used for

both the transmitte r and re ce iver power supplies.

Data and Signal Detect Outputs

Due to the high switching speeds of CML 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 LVTTL logic. A logic

low at this output indicates that the optical signal into

the receiver has been interrupted or that the light le vel

has fallen below the minimum signal-detect threshold.

This output should not be used as an error rate indica-

tor, 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 ex posed 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.
