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 transceiv ers

f eature 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 le vel 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 giv en 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 dischar ge (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 kΩ, 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-Wi ring Board Layout Considera tio ns

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 transmitte r and re ce iver 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 appro ximately 7 Ω.

Each output can provide approximately 50 mA maxi-

mum current to a 50 Ω load terminated to VCC – 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 preserv e 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

f or 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.

Tra nsc eiv er 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.
