Electrical Interfaces
The HFBR-5911LZ/ALZ interfaces with the host
circuit board through the ten I/O pins identified
by function in Table 4. These pins are sized for
use in boards between 0.062 in. and 0.100 in.
thick.
depicted in Figure 4.
The HFBR-5911LZ/ALZ transmit and receive
interfaces require PECL differential signal lines on
the host board. To simplify board requirements,
transmitter bias resistors and ac coupling capacitors
are incorporated into the transceiver module and
so are not required on the host board.
The Tx_Disable and Signal Detect lines require
TTL lines on the host board if they are to be
utilized. The transceiver will operate normally if
these lines are not connected on the host board.
Figure 2 depicts a recommended interface circuit
to link the HFBR-5911LZ/ALZ to the supporting
physical layer ICs.
Timing for the MSA compliant control signals
implemented in this transceiver are listed in Table
9 and diagramed in Figure 5.
PCB Assembly Process Compatibility
The HFBR-5911LZ/ALZ is compatible with industry-
standard wave solder and aqueous wash processes
as detailed in Table 10.
shipped with a process plug to keep out impinging
liquids, but is not intended to be immersed.
After assembly, the process plug should be kept
in place as a dust plug when the transceiver is
not in use.
Regulatory Compliance
The HFBR-5911LZ/ALZ complies with all applicable
l a w s
Table 11. Certification level is dependent of the
overall configuration of the host equipment. The
transceiver performance is offered as a figure of
merit to assist the designer.
Electrostatic Discharge (ESD)
The HFBR-5911LZ/ALZ is compatible with ESD
levels found in typical manufacturing and operating
environments as described in Table 11. In the
normal handling and operation of optical
transceivers, ESD is of concern in two
circumstances.
The first case is during handling of the transceiver
prior to soldering onto the host board. To protect
the device, it’s important to use normal ESD

handling precautions. These include using grounded
wrist straps, workbenches and floor mats wherever
the transceiver is handled.
The second case to consider is static discharges to
the exterior of the host equipment chassis after
assembly. If the optical interface is exposed to
the exterior of the host equipment cabinet, the
transceiver may be subject to system-level ESD
requirements.
EMI Immunity
Due to its shielded design, the EMI immunity of
the HFBR-5911LZ/ALZ exceeds typical industry
standards.
Electromagnetic Interference (EMI)
Equipment incorporating Gigabit transceivers is
typically subject to regulation by the FCC in the
United States, TUV in the European Union and
VCCI in Japan.
compliance to these standards is detailed in Table
11.
The metal housing and shielded design of the
HFBR-5911LZ/ALZ minimize the EMI challenge
facing the equipment designer.
Flammability
The HFBR-5911LZ/ALZ optical transceiver is made
of metal and high strength, heat resistant, chemical
resistant and UL 94V-0 flame retardant plastic.
