HFBR-53A5VEMZ/HFBR-53A5VFMZ
3.3 V 1 x 9 Fiber Optic Transceivers
for Gigabit Ethernet Low Voltage
Data Sheet
Description
The HFBR-53A5VEMZ transceivers from Avago Technolo-
gies allow the system designer to implement a range of
solutions for multimode Gigabit Ethernet applications.
The overall Avago transceiver produ­ ct consists of three
sections: the transmitter and receiver optical sub-
assemblies, an electrical subassembly, and the pack-
age housing which incorporates a duplex SC connector
receptacle.
Transmitter Section
The transmitter section of the HFBR-53A5VEMZ/FMZ
consists of an 850 nm Vertical Cavity Surface Emitting
Laser (VCSEL) in an optical subassembly (OSA), which
mates to the fiber cable. The OSA is driven by a cus-
tom, silicon bipolar IC which converts differential PECL
compatible logic signals into an analog laser diode
drive current.The high speed output lines are internally ac-
coupled and differen-tially terminate with a 100 Ω resistor.
Receiver Section
The receiver of the HFBR-53A5VEMZ/FMZ includes a
GaAs PIN photo-diode mounted together with a custom,
silicon bipolar transimpedance preamplifier IC in an
OSA. This OSA is mated to a custom silicon bipolar circuit
that provides post-amplification and quantization.
The post-amplifier also includes a Signal Detect circuit
which pro­vides aTTL logic-high output upon detection of
a usable input optical signal level. The high speed output
lines are internally ac-coupled.
