Figure 6. Recommended Board Layout Hole Pattern
Board Layout - Decoupling
Circuit and Ground Planes
It is important to take care in the
layout of your circuit board to
achieve optimum performance
from these transceivers. Figure 3
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 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 which defined the 2 x 5
package style. This drawing is
reproduced in Figure 6 with the
addition of ANSI Y14.5M
compliant dimensioning to be
used as a guide in the mechanical
layout of your circuit board.
Figure 7 shows the front panel
dimensions associated with such
a layout.
DIMENSIONS IN MILLIMETERS (INCHES)
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. 2 x 5 Transceiver module requires 16 PCB holes (10 I/O pins, 2 solder posts and 4 package grounding tabs).
Package grounding tabs should be 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.
