Board Layout - Decoupling Circuit, Ground Planes and
Termination Circuits
It is important to take care in the layout of your circuit board
to achieve optimum performance from these transceivers.
Figure 7 provides a good example of a schematic for a
power supply decoupling circuit that works well with these
parts. It is further recommended that a continuous 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. Figures 7 and
8 show two recommended termination schemes.
Board Layout - Hole Pattern
The Avago Technologies transceiver complies with the
circuit board “Common Transceiver Footprint” hole pattern
dened in the original multisource announcement which
dened the 2 x 5 package style. This drawing is reproduced
in Figure 9 with the addition of ANSI Y14.5M compliant
dimensioning to be used as a guide in the mechanical
layout of your circuit board.

NOTES:
1. THIS FIGURE DESCRIBES THE RECOMMENDED CIRCUIT BOARD LAYOUT FOR THE MT-RJ
TRANSCEIVER PLACED AT .550 SPACING.
2. THE HATCHED AREAS ARE KEEP-OUT AREAS RESERVED FOR HOUSING STANDOFFS. NO
METAL TRACES OR GROUND CONNECTION IN KEEP-OUT AREAS.
3. 10 PIN MODULE REQUIRES ONLY 16 PCB HOLES, INCLUDING 4 PACKAGE GROUNDING TAB
HOLES CONNECTED TO SIGNAL GROUND.
4. THE SOLDER POSTS SHOULD BE SOLDERED TO CHASSIS GROUND FOR MECHANICAL
INTEGRITY AND TO ENSURE FOOTPRINT COMPATIBILITY WITH OTHER SFF TRANSCEIVERS.

Regulatory Compliance
These transceiver products are intended to enable com-
mercial system designers to develop equipment that com-
plies with the various international regulations governing
certication of Information Technology Equipment. See
the Regulatory Compliance Table for details. Additional
information is available from your Avago Technologies
sales representative.
Electrostatic Discharge (ESD)
There are two design cases in which immunity to ESD
damage is important.
The rst 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 oor mats in ESD controlled areas.
The second case to consider is static discharges to the ex-
terior of the equipment chassis containing the transceiver
parts. To the extent that the MT-RJ 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 this high speed trans-
ceiver 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.
Immunity
Equipment utilizing these transceivers will be subject to
radio-frequency electromagnetic elds in some environ-
ments. These transceivers have a high immunity to such
elds.
