Signal Detect
The signal detect circuit works by
sensing the peak level of the received
signal and comparing this level to a
reference level. The signal detect is a
single ended output and is compat-
ible with TTL and CMOS levels. No
external termination is required.
Data Outputs
The receiver DATA and /DATA provide
PECL output levels. These outputs
are PECL compatible and are DC
coupled. Both outputs should be
terminated correctly. Refer to the
‘Termination Schemes’ section for
more detail about recommended
Figure 2a. Typical HFBR-591xE receiver output at +25° C, +3.3 V
termination techniques. Under loss
of light conditions the Data outputs
will switch randomly.
It is recommended that the Receiver
outputs be connected to 50 W trans-
mission lines. Refer to the ‘Board
Layout’ section for additional rec-
ommended PC board layout tech-
niques.
Figure 2a shows a typical HFBR-591xE
receiver data output waveform.
Figure 2b shows a typical HFCT-591xE
receiver data output waveform.
Test Fixture
The Small Form Factor (SFF) trans-
Figure 2b. Typical HFCT-591xE receiver output at +25° C, +3.3 V
ceiver test fixture, shown in Figure 3,
is available for easy test and evalua-
tion purposes.
It has a four layer FR-4 printed circuit
board with ground planes on both
sides. It is designed to be footprint
compatible for all single and multi -
mode Gigabit Ethernet variants.
