HFBR-5320
200 MBd Low-Cost SBCON
Multimode Fiber Transceiver
Data Sheet
Description
The HFBR-5320 SBCON transceiver from Avago provides
system designers with a product to implement a range
of solutions compliant with the IBM® Enterprise System
Connection (ESCON)® architecture.
Transmitter Section
The transmitter section of the HFBR-5320 utilizes 1300
nm Surface Emitting InGaAsP LED. The LED is packaged in an optical sub-assembly within the transmitter section. The LED is driven by a custom silicon IC
which converts differential PECL logic signals [ECL referenced (shifted) to a +5 Volt supply] into an analog LED
drive current.
Receiver Section
The receiver section of the HFBR-5320 utilizes an
InGaAs PIN photodiode coupled to a custom silicon transimpedance preamplifier IC. This PIN/preamplifier combination is coupled to a custom quantizer IC
which provides the final pulse shaping for the logic Data
Output and Status Flag function. The Data and Status Flag
Outputs are differential PECL compatible [ECL referenced
(shifted) to a +5 Volt power supply] logic outputs.
Package
The overall package concept for the Avago transceiver
consists of the following basic elements: two optical subassemblies, an electrical sub-assembly and the housing
with an integral duplex SBCON connector receptacle. This
is illustrated in Figure 1.
The package outline and pin-out are shown in Figures 2 and
3. The package includes internal shields for the electrical
and optical sub-assemblies to ensure low EMI emissions
and high immunity to EMI fields.

Figure 1. Block diagram.
The optical sub-assemblies utilize a high-volume assembly
process together with low-cost lens elements which result
in a cost-effective building block.
The electrical subassembly consists of a high-volume
multi-layer printed circuit board on which the IC circuits
and various surface-mount passive circuit elements are
attached.
The outer housing, including the SBCON-compliant duplex
connector receptacle, is molded of filled, non-conductive
UL 94V-0 flame retardant Ultem® plastic (U.L. File E121562)
to provide mechanical strength and electrical isolation.
The transceiver is attached to a printed circuit board with
28 signal pins (4 rows of 7 pins) and with the four slots on
the flanges which are located on the package sides. These
four slots on the flanges provide the primary mechanical
strength to withstand the loads imposed by the duplex
connectored fiber cables.
Applications Information
The Applications Engineering group in the Avago Optical
Communications Division is available to assist you with the
technical understanding associated with this transceiver.
You can contact them through your local Avago sales
representative.
Avago LED technology has produced 1300 nm LED devices
with lower aging characteristics than normally associated
with these technologies in the industry. The industry
convention is 1.5 dB aging for 1300 nm LEDs. The Avago
LED will normally experience less than half this amount
of aging over normal, commercial equipment mission-life
periods. Contact your local Avago sales representatives
for additional details.
Recommended Handling Precautions
It is advised that normal, anti-static precautions be taken
in the handling and assembly of these transceivers to
prevent damage which may be induced by electrostatic
discharge (ESD). The HFBR-5320 transceiver meets MilStd-883C Method 3015.4 Class 2.
Care should be used to avoid shorting the receiver Data
or Status Flag Outputs directly to ground without proper
current limiting impedance.
Solder and Wash Process Compatibility
The transceiver is delivered with a protective process plug
inserted into the duplex SBCON connector receptacle. This
process plug protects the optical sub-assemblies during
wave solder and aqueous wash processing and acts as a
dust cover during shipping. These transceivers are compatible with either industry standard wave or hand soldering
processes. The process plug part number is HFBR-5002.
Shipping Container
The transceiver is packaged in a shipping container designed to protect it from mechanical and ESD damage
during shipment or storage.
Board Layout - Decoupling Circuit and Ground Planes
It is important to take care in the layout of your circuit board
to achieve optimum performance from the transceiver.
Figure 3 provides a good example of a schematic for a
power supply decoupling circuit that works well with this
part. It is further recommended that a contiguous ground
plane be provided in the circuit board directly under the
transceiver to provide a low inductive ground for signal
return current. This recommendation is in keeping with
good high-frequency board layout practices.

Regulatory Compliance
This transceiver product is intended to enable commercial system designers to develop equipment that
complies with the various international regulations governing certification of Information Technology Equipment. See the Regulatory Compliance Table for details.
Additional information is available from your local
Avago sales representative.
Electromagnetic Interference (EMI)
Most equipment designs utilizing this high-speed transceiver from Avago will be required to meet the requirements of FCC in the United States, CENELEC EN55022
(CISPR 22) in Europe and VCCI in Japan.
Electrostatic Discharge (ESD)
There are two design cases in which immunity to ESD
damage is important.
Immunity
The first case is during handling of the transceiver prior
to mounting it on the circuit board. It is important to
use normal ESD handling precautions for ESD sensitive
devices. These precautions include using grounded
wrist straps, work benches, and floor mats in ESD controlled areas.
The second case to consider is static discharges to the
exterior of the equipment chassis containing the transceiver parts. To the extent that the SBCON-compatible
duplex connector receptacle is exposed to the outside
of the equipment chassis, it may be subject to whatever
ESD system level test criteria that the equipment is intended to meet.
This device is suitable for a variety of applications utilizing the IBM® ESCON® / SBCON architecture.
Equipment utilizing this transceiver will be subject to
radio-frequency electromagnetic fields in some environments. This transceiver has a high immunity to such
fields.
Ordering Information

Notes:
1. This is the maximum voltage that can be applied across the
Differential Transmitter Data Inputs to prevent damage to the
input ESD protection circuit.
2. The outputs are terminated with 50 Ω connected to VCC –2 V.
3. The power supply current needed to operate the transmitter is
provided to differential ECL circuitry. This circuitry maintains a
nearly constant current flow from the power supply. Constant
current operation helps to prevent unwanted electrical noise
from being generated and conducted or emitted to neighboring
circuitry.
4. This value is measured with the outputs terminated into 50 Ω
connected to VCC –2 V and an Input Optical Power Level of –14.5
dBm average.
5. The power dissipation value is the power dissipated in the receiver
itself. Power dissipation is calculated as the sum of the products of
supply voltage and currents, minus the sum of the products of the
output voltages and currents.
6. This value is measured with respect to VCC with the output
terminated into
50 Ω connected to VCC –2 V.
7. The output rise time and fall times are measured between 20%
and 80% levels with the output connected to VCC – 2 V through
50 Ω.
8. Eye-width specified defines the minimum clock time-position
range, centered around the center of the 5 ns baud interval, at
which the BER must be 10–12 or better. Test data pattern is PRBS
27–1. The maximum change in input optical power to open the
eye to 1.4 nsec from a closed eye is 1.0 dB.
9. These optical power values are measured with the following
conditions:
• The Beginning of Life (BOL) to the End of Life (EOL) optical
power degradation is assumed to be 1.5 dB per the industry
convention for long wavelength LEDs. The actual degradation
observed in normal commercial environments will be <1.0 dB
with Avago’s 1300 nm LED products.
• Over the specified operating voltage and temperature ranges.
• Input Signal: 27 –1 data pattern PseudoRandom Bit-Stream, 200
Mbit/sec NRZ code.
10. Input conditions: 100 MHz, square wave signal, input voltages are
in the range specified for VIL and VIH.
11. From an assumed Gaussian-shaped wavelength distribution, the
relationship between FWHM and RMS values for Spectral Width is
2.35 x RMS = FWHM.
12. Measured with electrical input signal rise and fall time of 0.35 to
1.3 ns (20-80%) at the transmitter input pins. Optical output rise
and fall times are measured between 20% and 80% levels.
13. Transmitter Systematic Jitter is equal to the sum of Duty Cycle
Distortion (DCD) and Data Dependent Jitter (DDJ). DCD is
equivalent to Pulse-Width Distortion (PWD). Systematic Jitter
is measured at the 50% signal level with 200 MBd, PRBS 27 –1
electrical input data pattern.
6
14. This specification is intended to indicate the performance of the
receiver section of the transceiver when Input Optical Power
signal characteristics are present per the following conditions.
The Input Optical Power dynamic range from the minimum level
(with a window time-width) to the maximum level is the range
over which the receiver is guaranteed to provide output data with
a Bit Error Ratio (BER) better than or equal to
10–15.
• At the Beginning of Life (BOL).
• Over the specified operating temperature and voltage ranges.
• Receiver data window time-width is
1.4 ns or greater
and centered at mid-symbol.
• Input signal is 200 MBd, PseudoRandom-Bit-Stream 27 –1 data
pattern.
• Transmitter cross-talk effects have been included in Receiver
sensitivity. Transmitter should be running at 50% duty cycle
(nominal) between 8 - 200 Mbps, while Receiver sensitivity is
measured.
15. All conditions of note 14 apply except that the measurement is
made at the center of the symbol with no window time-width.
16. The receiver systematic jitter specification applies to optical
powers between –14.5 dBm avg. to –27.0 dBm avg. at the
receiver. Receiver Systematic Jitter is equal to the sum of Duty
Cycle Distortion (DCD) and Data Dependent Jitter (DDJ). DCD
is equivalent to Pulse-Width Distortion (PWD). Systematic Jitter
is measured at the 50% signal level with 200 MBd, PRBS 27 –1
electrical output data pattern.
17. Status Flag switching thresholds: Direction of decreasing optical
power If Power >–36.0 dBm avg., then SF = 1 (high)
If Power <–45.0 dBm avg., then SF = 0 (low)
Direction of increasing optical power:
If Power <–45.5 dBm avg., then SF = 0 (low)
If Power >–35.5 dBm avg., then SF = 1 (high)
18. Status Flag Hysteresis is the difference in low-to-high and highto-low switching thresholds. Thresholds must lie within optical
power limits specified. The Hysteresis is desired to avoid Status
Flag chatter when the optical input is near the threshold.
19. The Status Flag output shall be asserted with 500 µs after a step
increase of the Input Optical Power. The step will be from a low
Input Optical Power <–45.5 dBm avg., to
>–35.5 dBm
avg.
20. Status Flag output shall be de-asserted within 500 µs after a step
decrease in the Input Optical Power. The Step will be from a high
Input Optical Power >–36.0 dBm avg. to <–45.0 dBm avg.
21. This value is measured with an output load of RL = 10 kΩ.
22. The Extinction Ratio is a measure of the modulation depth of the
optical signal. The data “0” output optical power is compared to
the data “1” peak output optical and expressed in decibels. With
the transmitter driven by a HALT Line State (12.5 Mhz squarewave) signal, the average optical power is measured. The data “1”
peak power is then calculated by adding 3 dB to the measured
average optical power. The data “0” output optical power is found
by measuring the optical power when the transmitter is driven
by a logic “0” input. The Extinction Ratio is the ratio of the optical
power at the “0” level compared to the optical power at the “1”
level expressed in decibels.

Notes:
1. Resistance is in Ohms. Capacitance is in microfarads. Inductance is in microhenries.
2. Terminal transmitter input Data and Data-bar at the transmitter input pins. Terminate the receiver Output Data, Data-bar, Status Flag, and Status
Flag-bar at the follow-on device input pins. For lower power dissipation in the Status Flag termination circuitry with small compromise to the
signal quality, each Status Flag output can be loaded with 510 Ohms to ground instead of the two resistor, split -load PECL termination shown in
the Figure 3 schematic.
3. Make differential signal paths short and same length with equal termination impedance.
4. Signal traces should be 50 Ohms microstrip or stripline transmission lines. Use multilayer, ground-plane printed circuit board for best high-frequency
performance.
5. Use high-frequency, monolithic ceramic bypass capacitors and low series dc resistance inductors. Recommend use of surface-mount coil
inductors and capacitors. In low noise power supply systems, ferrite bead inductors can be substituted for coil inductors. Locate power supply
filter components close to their respective power supply pins.
6. Device ground pin should be directly and individually connected to ground.
7. Caution: Do not directly connect the fiber-optic module PECL outputs (Data, Data-bar, Status flag, Status Flag-bar, VBB) to ground without proper
current limiting impedance.
