HFBR-24x6Z Low-Cost 125 MHz Receiver
Description
The HFBR-24x6Z fiber optic receiver is designed to oper-
ate with the Avago Technologies HFBR-14xxZ fiber optic
transmitters and 50/ 125 μm, 62.5/125 μm, 100/140 μm
and 200 μm HCS® fiber optic cable. Consistent coupling
into the receiver is assured by the lensed optical system
(Figure 1). Response does not vary with fiber size for core
diameters of 100 μm or less.
The receiver output is an analog signal which allows
follow-on circuitry to be optimized for a variety of dis-
tance/data rate requirements. Low-cost external compo-
nents can be used to convert the analog output to logic
compatible signal levels for various data formats and
data rates up to 175 MBd. This distance/data rate trade-
off results in increased optical power budget at lower
data rates which can be used for additional distance or
splices.
The HFBR-24x6Z receiver contains a PIN photodiode
and low noise transimpedance preamplifier integrated
circuit. The HFBR-24x6Z receives an optical signal and
converts it to an analog voltage. The output is a buffered

CAUTION: The small junction sizes inherent to the design of these components increase the components’ susceptibility to damage
from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these compo-
nents to prevent damage and/or degradation which may be induced by ESD.

emitter follower. Because the signal amplitude from the
HFBR-24x6Z receiver is much larger than from a simple
PIN photodiode, it is less susceptible to EMI, especially
at high signaling rates. For very noisy environments,
the conductive or metal port option is recommended.
A receiver dynamic range of 23 dB over temperature is
achievable (assuming 10-9 BER).
The frequency response is typically dc to 125 MHz.
Although the HFBR-24x6Z is an analog receiver, it is
compatible with digital systems. Please refer to Applica-
tion Bulletin 78 for simple and inexpensive circuits that
operate at 155 MBd or higher.
The recommended ac coupled receiver circuit is shown
in Figure 14. It is essential that a 10 ohm resistor be con-
nected between pin 6 and the power supply, and a 0.1
mF ceramic bypass capacitor be connected between the
power supply and ground. In addition, pin 6 should be
filtered to protect the receiver from noisy host systems.
Refer to AN 1038, 1065, or AB 78 for details.
