Appendix B:
PCB Layout Suggestion
The following PCB layout
guidelines should be followed to
obtain a good PSRR and EM
immunity resulting in good
electrical performance. Things to
note:
1. The ground plane should be
continuous under the part,
but should not extend under
the shield trace.
2. The shield trace is a wide, low
inductance trace back to the
system ground.
3. VLED can be connected to
either unfiltered or
unregulated power supply. If
VLED and Vcc share the same
power supply, CX3 need not
be used and the connections
for CX1 and CX2 should be
before the current limiting
resistor R1. In a noisy
environment, including
capacitor CX2 can enhance
supply rejection. CX1 is
generally a ceramic capacitor
of low inductance providing a
wide frequency response
while CX2 and CX3 are
tantalum capacitors of big
volume and fast frequency
response. The use of a
tantalum capacitor is more
critical on the VLED line,
which carries a high current.
4. Preferably a multi-layered
board should be used to
provide sufficient ground
plane. Use the layer
underneath and near the
transceiver module as Vcc,
and sandwich that layer
between ground connected
board layers. Refer to the
diagram below for an example
of a four-layer board.
The area underneath the module
at the second layer, and 3 cm in
all directions around the
module, is defined as the critical
ground plane zone. The ground
plane should be maximized in

this zone. Refer to application
note AN1114 or the Avago IrDA
Data Link Design Guide for
details. The layout below is
based on a two-layer PCB.
