HFBR-5301

Fibre Channel 133 MBd and 266 MBd Transceivers in Low Cost 1x9 Package Style

plane be provided in the circuit

board directly under the

transceiver to provide a low

inductance ground for signal

return current. This recommen-

dation is in keeping with good

high frequency board layout

practices.

Board Layout - Hole Pattern

The Hewlett-Packard transceiver

complies with the circuit board

“Common Transceiver Footprint”

hole pattern defined in the

original multisource announce-

ment for the 1x9 pin package

style. This drawing is reproduced

in Figure 7 with the addition of

ANSI Y14.5M compliant dimen-

sioning to be used as a guide in

the mechanical layout of your

circuit board.

Board Layout – Art Work

The Applications Engineering

group has developed Gerber file

art work for a multilayer printed

circuit board layout incorporating

the recommendations above.

Contact your local Hewlett-

Packard sales representative for

details.

Regulatory Compliance

These transceiver products are

intended to enable system

designers to develop equipment

that complies with the various

international regulations govern-

ing certification of Information

Technology Equipment. See the

Regulatory Compliance Table for

details.

Electromagnetic Interference

(EMI)

Most equipment designs utilizing

these high-speed transceivers

from Hewlett-Packard will need

to meet the requirements of the

FCC in the United States,

CENELEC EN55022 (CISPR 22)

in Europe and VCCI in Japan.

The HFBR-5301 and HFBR-5302

are suitable for use in designs

ranging from a single transceiver

in a desktop computer to large

quantities of transceivers in a

hub, switch or concentrator.

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 mount-

ing it on the circuit board. You

should 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 contain-

ing the transceiver parts. To the

extent that the transceiver 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.

Immunity

Equipment utilizing these trans-

ceivers will be subject to radio-

frequency electromagnetic fields

in some environments. These

transceivers have a high immunity

to such fields (see AN1075,

“Testing and Measuring Electro-

magnetic Compatibility Perfor-

mance of the HFBR-510X/520X

Fiber-Optic Transceivers,” 5963-

3358E).

Transceiver Reliability and

Performance Qualification

Data

The 1x9 transceivers have passed

Hewlett-Packard reliability and

performance qualification testing

and are undergoing ongoing

quality monitoring. Details are

available from your Hewlett-

Packard sales representative.

These transceivers are manu-

factured at the Hewlett-Packard

Singapore location which is an

ISO 9002 certified facility.
