Figure 9 - Recommended Board Layout Hole Pattern
Power Supply Filtering and Ground Planes
It is important to exercise care in circuit board layout
to achieve optimum performance from these trans-
ceivers. Figures 7 and 8 show the power supply circuit
which complies with the small form factor multisource
agreement. It is further recommended that a continu-
ous ground plane be provided in the circuit board di-
rectly 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.
Package footprint and front panel considerations
The Avago Technologies transceiver complies with the
circuit board “Common Transceiver Footprint” hole
pattern defined in the current multisource agreement
which defined the 2 x 5 and 2 x 10 package styles. 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.
Figure 10 shows the front panel dimensions associated
with such a layout.

Eye Safety Circuit
For an optical transmitter device to be eye-safe in the
event of a single fault failure, the transmitter must ei-
ther maintain eye-safe operation or be disabled.
The HFCT-5953xxx/HFCT-5954xxx is intrinsically eye
safe and does not require shut down circuitry.
Signal Detect
The Signal Detect circuit provides a deasserted output
signal when the optical link is broken (or when the re-
mote transmitter is OFF). The Signal Detect threshold
is set to transition from a high to low state between
the minimum receiver input optional power and -45
dBm avg. input optical power indicating a definite opti-
cal fault (e.g. unplugged connector for the receiver or
transmitter, broken fiber, or failed far-end transmitter or
data source). The Signal Detect does not detect receiver
data error or error-rate. Data errors can be determined
by signal processing offered by upstream PHY ICs.
