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 DC balanced code.
TX Disable
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 transient fault can be cleared by cycling the TX Disable control input.
Eye Safety Circuit
Signal Detect
For an optical transmitter device to be eye-safe in the event of a single fault failure, the transmitter will either maintain normal, eye-safe 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 Signal Detect (SD) circuit which provides an LVTTLcompatible logic low output in the absence of a usable input optical signal level.
The Signal Detect (SD) output indicates if the optical input signal to the receiver does not meet the minimum detectable level for Fibre Channel compliant signals. When SD is low it indicates loss of signal. When SD is high it indicates normal operation. The Signal Detect 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
The HFBR-5921L/5923L 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. The TX Disable control should be actuated upon initialization of the module. See Figure 6 for product timing diagrams.
TX Fault (Available only on the 2 x 6)
Agilent's HFBR-5921L/5923L fiber-optic 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- 5921/5923. Caution should be taken to account for the proper interconnection between the supporting Physical Layer integrated circuits and the HFBR-5921L/5923L . Figure 4 illustrates the recommended interface circuit.

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)
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.
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-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.
Eye Safety
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 4
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: Regulatory Compliance, under normal operating conditions and under a single fault condition.

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 K 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 K 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 K resistor to VCCR. 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. 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 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.

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.
