well. It is further recommended
that a contiguous ground plane
be provided in the circuit board
directly under the transceiver to
provide a low inductance ground
for signal return current. This
recommendation is in keeping
with good high frequency board
layout practices.
Board Layout – Hole
Pattern
This Hewlett-Packard transceiver
complies with the circuit board
“Common Transceiver Footprint”
hole pattern defined in the
original multisource announce-
ment which defined the 1x9
package style. This drawing is
reproduced in Figure 8 with the
addition of ANSI Y14.5N
compliant dimensioning 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
artwork for a multilayered printed
circuit board layout incorporating
the above recommendations.

Board Layout –
Mechanical
For applications providing a
choice of either a duplex SC or a
duplex ST connector interface,
while utilizing the same pinout on
the printed circuit board, the ST
port needs to protrude from the
chassis panel a minimum of 9.53
mm for sufficient clearance to
install the ST connector.
Please refer to Figure 8a for a
mechanical layout detailing the
recommended location of the
duplex SC and duplex ST
transceiver packages in relation
to the chassis panel.
Regulatory Compliance
These transceiver products are
intended to enable commercial
system designers to develop
equipment that complies with the
various international regulations
governing certification of Infor-
mation Technology Equipment.
See the Regulatory Compliance
Table for details. Additional

is contacted by a Human Body Model probe.
Typically provide a 10 dB margin to the noted
standard limits when tested at a certified test range
without a chassis enclosure.
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.
Typically withstand at least 25 kV without damage

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 precau-
tions include using grounded
wrist straps, work benches, and
floor mats in ESD controlled
areas.
The second case is static
discharges to the exterior of the
equipment chassis containing the
transceiver 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 equip-
ment is intended to meet.
