ATM Transceivers for SONET OC-3 / SDH STM-1 in Low Cost 1 x 9 Package Style

Avago Technologies 

Regulatory Compliance

These transceiver products are intended to enable com-

mercial system designers to develop equipment that

complies with the various international regulations gov-

erning certification of Information Technology Equip-

ment. See the Regulatory Compliance Table for details.

Additional information is available from your Avago Tech-

nologies sales representative.

Electrostatic Discharge (ESD)

There are two design cases in which immunity to ESD

damage is important.

The first case is during handling of the transceiver prior

to mounting it on the circuit board. It is important to

use normal ESD handling precautions for ESD sensitive

devices. These precautions include using grounded wrist

straps, work benches, and floor mats in ESD controlled

areas.

The second case to consider is static discharges to the

exterior of the equipment chassis containing the trans-

ceiver parts. To the extent that the duplex SC connector

is exposed to the outside of the equipment chassis it may

be subject to whatever ESD system level test criteria that

the equipment is intended to meet.

Electromagnetic Interference (EMI)

Most equipment designs utilizing these high speed trans-

ceivers from Avago Technologies will be required to meet

the requirements of FCC in the United States, CENELEC

EN55022 (CISPR 22) in Europe and VCCI in Japan.

These products are suitable for use in designs ranging

from a desktop computer with a single transceiver to a

concentrator or switch product with large number of

transceivers.

In all well-designed chassis, the two 0.5” holes required

for ST connectors to protrude through will provide 4.6 dB

more shielding than one 1.2” duplex SC rectangular

cutout. Thus, in a well-designed chassis, the duplex ST 1 x

9 transceiver emissions will be identical to the duplex SC

1 x 9 transceiver emissions.

Withstand up to 2200 V applied between electrical pins

Typically withstand at least 25 kV without damage when the Duplex

SC Connector Receptacle is contacted by a Human Body Model

probe.

Transceivers typically provide a 13 dB margin (with duplex SC

receptacle) or a 9 dB margin (with duplex ST receptacles) to the

noted standard limits. However, it should be noted that final margin

depends on the customer’s board and chassis design.

Typically show no measurable effect from a 10 V/m field swept from

10 to 450 MHz applied to the transceiver when mounted to a circuit

card without a chassis enclosure.
