Module Package The transceiver meets the Small Form Pluggable (SFP) industry standard package utilizing an integral LC-Duplex optical interface connector. The hotpluggable capability of the SFP package allows the module to be installed at any time - even with the host system operating and online. This allows for system configuration changes or maintenance without system down time. The HFBR-5720AL/ ALP uses a reliable 850 nm VCSEL source and requires a 3.3 V DC power supply for optimal design. Module Diagrams Figure 1 illustrates the major functional components of the HFBR-5720AL/ALP. The connection diagram of the module is shown in Figure 2. Figure 7 depicts the external configuration and dimensions of the module.
Installation The HFBR-5720AL/ALP can be installed in or removed from any MultiSource Agreement (MSA)compliant Small Form Pluggable port regardless of whether the host equipment is operating or not. The module is simply inserted, electrical interface first, under finger pressure. Controlled hot-plugging is ensured by design and by 3-stage pin sequencing at the electrical interface. The module housing makes initial contact with the host board EMI shield mitigating potential damage due to Electro-Static Discharge (ESD). The 3-stage pin contact sequencing involves (1) Ground, (2) Power, and then (3) Signal pins, making contact with the host board surface mount connector in that order. This printed circuit board card-edge connector is depicted in Figure 2.
Serial Identification (EEPROM) The HFBR-5720AL/ALP complies with an industry standard MSA that defines the serial identification protocol. This protocol uses the 2-wire serial CMOS E2PROM protocol of the ATMEL AT24C01A or equivalent. The contents of the HFBR5720AL/ALP serial ID memory are defined in Table 10 as specified in the SFP MSA.

Transmitter Section The transmitter section includes the transmitter optical subassembly (TOSA) and laser driver circuitry. The TOSA, containing an 850 nm VCSEL (Vertical Cavity Surface Emitting Laser) light source, is located at the optical interface and mates with the LC optical connector. The TOSA is driven by a custom silicon IC, which converts differential logic signals into an analog laser diode drive current. This Tx driver circuit regulates the optical power at a constant level provided the data pattern is valid 8B/10B balanced code. Tx Disable The HFBR-5720AL/ALP accepts a transmit disable control signal input which shuts down the transmitter. A high signal implements this function while a low signal allows normal laser operation. In the event of a fault (e.g., eye safety circuit activated), cycling this control signal resets the module as depicted in
Figure 6. The Tx Disable control should be actuated upon initialization of the module. Tx Fault The HFBR-5720AL/ALP module features a transmit fault control signal output which when high indicates a laser transmit fault has occurred and when low indicates normal laser operation. A transmitter fault condition can be caused by deviations from the recommended module operating conditions or by violation of eye safety conditions. A fault is cleared by cycling the Tx Disable control input. Eye Safety Circuit For an optical transmitter device to be eye-safe in the event of a single fault failure, the transmitter will either maintain normal eyesafe operation or be disabled. In the event of an eye safety fault, the VCSEL will be disabled.
Receiver Section The receiver section includes the receiver optical subassembly (ROSA) and amplification/ quantization circuitry. The ROSA, containing a PIN photodiode and custom transimpedance preamplifier, is located at the optical interface and mates with the LC optical connector. The ROSA is mated to a custom IC that provides post-amplification and quantization. This circuit also includes a loss of signal (LOS) detection circuit which provides an open collector logic high output in the absence of a usable input optical signal level. Loss of Signal The Loss of Signal (LOS) output indicates that the optical input signal to the receiver does not meet the minimum detectable level for Fibre Channel compliant signals. When LOS is high it indicates loss of signal. When LOS is low it indicates normal operation. The Loss of Signal

thresholds are set to indicate a definite optical fault has occurred (e.g., disconnected or broken fiber connection to receiver, failed transmitter). Functional Data I/O Agilent's HFBR-5720AL/ALP fiberoptic transceiver is designed to accept industry standard differential signals. In order to reduce the number of passive components required on the customer's board, Agilent has included the functionality of the transmitter bias resistors and coupling capacitors within the fiber optic module. The transceiver is compatible with an "AC-coupled" configuration and is internally terminated. Figure 1 depicts the functional diagram of the HFBR-5720AL/ALP. Caution should be taken for the proper interconnection between the supporting Physical Layer integrated circuits and the HFBR5720AL/ALP. Figure 4 illustrates the recommended interface circuit. Several MSA compliant control data signals are implemented in the module and are depicted in Figure 6.
Application Support Evaluation Kit To help you in your preliminary transceiver evaluation, Agilent offers a 2.125 GBd Fibre Channel evaluation board. This board will allow testing of the fiber-optic VCSEL transceiver. Please contact your local field sales representative for availability and ordering details. Reference Designs Reference designs for the HFBR5720AL/ALP 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 MSA power supply filter circuit design. All artwork is available at the Agilent Website. Please contact your local field sales engineer for more information regarding application tools. Regulatory Compliance 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.
Electrostatic Discharge (ESD) 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 insertion into the transceiver port. 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-5720AL/ ALP 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 outsid e of the host equipment chassis, it may be subject to system-level ESD requirements. The ESD performance of the HFBR5720AL/ALP exceeds typical industry standards.

Immunity Equipment hosting the HFBR5720AL/ALP modules will be subjected to radio-frequency electro-magnetic fields in some environments. These transceivers have good immunity to such fields due to their shielded design. Electromagnetic Interference (EMI) Most equipment designs utilizing these high-speed transceivers from Agilent 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-5720AL/ALP 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 perfornmance. Eye Safety These 850 nm VCSEL-based transceivers provide Class 1 eye safety by design. Agilent Technologies has tested the transceiver design for compliance with the requirements listed in Table 1 under normal operating conditions and under a single fault condition Reliability These transceivers have an estimated failure rate of <100 FITS @ 50C.
Flammability The HFBR-5720AL/ALP VCSEL transceiver housing is made of metal and high strength, heat resistant, chemically resistant, and UL 94V-0 flame retardant plastic. Caution There are no user serviceable parts nor any maintenance required for the HFBR-5720AL/ ALP. Tampering with or modifying the performance of the HFBR5720AL/ALP will result in voided product warranty. It may also result in improper operation of the HFBR-5720AL/ALP circuitry, and possible overstress of the laser source. Device degradation or product failure may result. Connection of the HFBR-5720AL/ ALP to a non-approved optical source, operating above the recommend-ed absolute maximum conditions or operating the HFBR-5720AL/ALP 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.

Notes: 1. Tx Fault is an open collector/drain output which should be pulled up externally with a 4.7 K - 10 K resistor on the host board to a supply < VCCT+0.3 V or VCCR+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. 2. Tx disable input is used to shut down the laser output per the state table below. It is pulled up within the module with a 4.7 K - 10 K resistor. Low (0 - 0.8 V): Transmitter On Between (0.8 V and 2.0 V): Undefined High (2.0 - 3.63 V): Transmitter Disabled Open: Transmitter Disabled 3. Mod-Def 0,1,2. are the module definition pins. They should be pulled up with a 4.7 K - 10 K resistor on the host board to a supply less than VCCT+0.3 V or VCCR+0.3 V. Mod-Def 0 is grounded by the module to indicate that the module is present Mod-Def 1 is clock line of two wire serial interface for optional serial ID Mod-Def 2 is data line of two wire serial interface for optional serial ID 4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7 K - 10 K resistor on the host board to a supply < VCCT, R+0.3 V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V. 5. RD-/+: These are the differential receiver outputs. They are AC coupled 100 differential lines which should be terminated with 100 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. 6. VCCR and VCCT are the receiver and transmitter power supplies. They are defined as 2.97 - 3.63 V at the SFP connector pin. The maximum supply current is 200 mA and the associated in-rush current will typically be no more than 30 mA above steady state after 500 nanoseconds. 7. TD-/+: These are the differential transmitter inputs. They are AC coupled differential lines with 100 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 500 - 2400 mV (250 - 1200 mV single ended), though it is recommended that values between 500 and 1200 mV differential (250 - 600 mV single ended) be used for best EMI performance. These levels are compatible with CML and LVPECL voltage swings.
