Agilent HFBR-53A5VEM/HFBR-53A5VFM
3.3 V 1 x 9 Fiber Optic Transceivers
for Gigabit Ethernet Low Voltage
Data Sheet
Description
The HFBR-53A5VM transceivers
from Agilent Technologies allow the
system designer to implement a
range of solutions for multimode
Gigabit Ethernet applications.
The overall Agilent transceiver
product consists of three sections:
the transmitter and receiver optical
subassemblies, an electrical
subassembly, and the package
housing which incorporates a
duplex SC connector receptacle.
Transmitter Section
The transmitter section of the
HFBR-53A5VEM/FM 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 custom, 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
differentially terminate with a 100
resistor.
Receiver Section
The receiver of the
HFBR-53A5VEM/FM 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 pro-
vides a TTL logic-high output
upon detection of a usable input
optical signal level. The high
speed output lines are internally
ac-coupled.

Notes:
1. The Laser Reset Voltage is the voltage level below which the VCCT voltage must be lowered to cause the laser driver circuit to reset from an
electrical/optical shutdown condition to a proper electrical/optical operating condition. The maximum value corresponds to the worst-case
highest VCC voltage necessary to cause a reset condition to occur. The laser safety shutdown circuit will operate properly with transmitter VCC
levels of 2.5 Vdc VCC 5.0 Vdc.
2. These outputs are compatible with 10 K, 10 KH, and 100 K ECL and PECL inputs.
3. These are 20-80% values.
4. Under recommended operating conditions.
