Application Support
Electrostatic Discharge (ESD)
Evaluation Kit
Reference designs for the HFBR-5921L/5923L fiber-optic
transceiver and the HDMP-2630/2631 physical layer IC
are available to assist the equipment designer. Figure 4
depicts a typical application configuration, while Figure
5 depicts the multisourced power supply filter circuit design. All artwork is available at the Avago electronic bulletin board. Please contact your local field sales engineer for
more information regarding application tools.
There are two conditions in which immunity to ESD damage is important. Table 1 documents our immunity to
both of these conditions. The first condition is during handling of the transceiver prior to attachment to the PCB.
To protect the transceiver, it is important to use normal
ESD handling precautions. These precautions include
using grounded wrist straps, work benches, and floor
mats in ESD controlled areas. The ESD sensitivity of the
HFBR-5921L/5923L is compatible with typical industry
production environments. The second condition is static
discharges to the exterior of the host equipment chassis
after installation. To the extent that the duplex LC optical
interface is exposed to the outside of the host equipment
chassis, it may be subject to system-level ESD requirements. The ESD performance of the HFBR-5921L/5923L
exceeds typical industry standards.
Regulatory Compliance
Immunity
See Table 1 for transceiver Regulatory Compliance performance. The overall equipment design will determine the
certification level. The transceiver performance is offered
as a figure of merit to assist the designer.
Equipment hosting the HFBR-5921L/5923L modules will
be subjected to radio-frequency electromagnetic fields in
some environments. The transceivers have good immunity to such fields due to their shielded design.
To help you in your preliminary transceiver evaluation,
Avago offers a 2.125 GBd Fibre Channel evaluation board.
This board will allow testing of the HFBR-5921L/ 5923L
optical transceivers. Please contact your local field sales
representative for availability and ordering details.

Electromagnetic Interference (EMI)
Caution
Most equipment designs utilizing these high-speed transceivers from Avago Technologies will be required to meet
the requirements of FCC in the United States, CENELEC
EN55022 (CISPR 22) in Europe and VCCI in Japan. The metal housing and shielded design of the HFBR-5921L/5923L
minimize the EMI challenge facing the host equipment
designer. These transceivers provide superior EMI performance. This greatly assists the designer in the management of the overall system EMI performance.
There are no user serviceable parts nor is any maintenance required for the HFBR-5921/5923. All adjustments
are made at the factory before shipment to our customers. Tampering with or modifying the performance of the
HFBR-5921L/5923L will result in voided product warranty. It may also result in improper operation of the HFBR5921L/5923L circuitry, and possible overstress of the laser
source. Device degradation or product failure may result.
Connection of the HFBR-5921L/5923L to a nonapproved
optical source, operating above the recommended absolute maximum conditions or operating the HFBR5921L/5923L in a manner inconsistent with its design and
function may result in hazardous radiation exposure and
may be considered an act of modifying or manufacturing
a laser product. The person(s) performing such an act is
required by law to re-certify and re-identify the laser product under the provisions of U.S. 21 CFR (Subchapter J) and
the TUV.
Eye Safety
These 850 nm VCSEL-based transceivers provide Class 1
eye safety by design. Avago Technologies has tested the
transceiver design for compliance with the requirements
listed in Table 1: Regulatory Compliance, under normal
operating conditions and under a single fault condition.
Flammability
The HFBR-5921L/5923L VCSEL transceiver housing is made
of metal and high strength, heat resistant, chemically resistant, and UL 94V-0 flame retardant plastic.

Transmitter Fault Indication – High indicates a Fault
2
Notes:
1. Transmitter and Receiver Ground are common in the internal module PCB. They are electrically connected to signal ground within the module,
and to the housing shield (see Note 5 in Figure 7c). This housing shield is electrically isolated from the nose shield which is connected to chassis
ground (see Note 4 in Figure 7c).
2. TX Fault is an open collector/drain output, which should be pulled up externally with a 4.7 K – 10 KΩ resistor on the host board to a supply
< VCC T + 0.3 V or VCC R + 0.3 V. When high, this output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the
output will be pulled to < 0.8 V.
3. TX disable input is used to shut down the laser output per the state table below. It is pulled down internally within the module with a 6.8 KΩ
resistor.
Low (0 – 0.8 V):
Transmitter on
Between (0.8 V and 2.0 V):
Undefined
High (2.0 – 3.465 V):
Transmitter Disabled
Open:
Transmitter Enabled
4. SD (Signal Detect) is a normally high LVTTL output. When high it indicates that the received optical power is adequate for normal operation.
When Low, it indicates that the received optical power is below the worst case receiver sensitivity, a fault has occurred, and the link is no longer
valid. SD is pulled up internally with a 2 KΩ resistor to VCCR.
5. RD-/+: These are the differential receiver outputs. They are AC coupled 100 Ω differential lines which should be terminated with 100 Ω differential
at the user SerDes. The AC coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will
be between 400 and 2000 mV differential (200 – 1000 mV single ended) when properly terminated. These levels are compatible with CML and
LVPECL voltage swings.
6. VCC R and VCCT are the receiver and transmitter power supplies. They are defined as 3.135 – 3.465 V at the PTH connector pin. The maximum
supply current is 200 mA.
7. TD-/+: These are the differential transmitter inputs. They are AC coupled differential lines with 100 Ω differential termination inside the module.
The AC coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 400 – 2400 mV
(200 – 1200 mV single ended), though it is recommended that values between 400 and 1200 mV differential (200 – 600 mV single ended) be used for
best EMI performance. These levels are compatible with CML and LVPECL.

1. Internally AC coupled and terminated (100 Ohm differential). These levels are compatible with CML and LVPECL voltage swings.
2. Internally AC coupled with an external 100 ohm differential load termination.
3. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern.
4. Contributed RJ is calculated for 1x10 -12 BER by multiplying the RMS jitter (measured on a single rise or fall edge) from the oscilloscope by 14. Per
the FC-PI standard (Table 13 - MM jitter output, Note 1), the actual contributed RJ is allowed to increase above its limit if the actual contributed
DJ decreases below its limits, as long as the component output DJ and TJ remain within their specified FC-PI maximum limits with the worst
case specified component jitter input.
5. 20%-80% Rise and Fall times measured with a 500 MHz signal utilizing a 1010 data pattern.
6. In a network link, each component’s output jitter equals each component’s input jitter combined with each component’s contributed jitter.
Contributed DJ adds in a linear fashion and contributed RJ adds in a RMS fashion. In the Fibre Channel FC-PI Rev 11 specification “6.3.3 MM
jitter budget” section, there is a table specifying the input and output DJ and TJ for the receiver at each data rate. In that table, RJ is found from
TJ - DJ where the RX input jitter is noted as Gamma R and the RX output jitter is noted as Delta R. Our component contributed jitter is such that,
if the maximum specified input jitter is present, and is combined with our maximum contributed jitter, then we meet the specified maximum
output jitter limits listed in the FC-PI MM jitter specification table.
