Description
The 2417G4A and 2417H4A transceivers are high­speed, cost-effective optical transceivers that are compliant with the International Telecommunication Union Telecommunication (ITU-T) G.957 specifica­tions for use in ATM, SONET, and SDH applications. The 2417G4A operates at the OC-3/STM-1 rate of 155 Mbits/s, and the 2417H4A operates at the OC­12/STM-4 rate of 622 Mbits/s. The transceivers fea­ture Agere Systems high-reliability optics and are packaged in a narrow-width plastic housing with an LC duplex receptacle. This receptacle fits into an RJ-45 form-factor outline. The 10-pin package and pinout conform to a multisource transceiver agree­ment.
The transmitter features differential LVPECL logic level data inputs and an LVTTL logic level disable input. The receiver f eatu res differential LVPECL logic level data and an LVPECL logic level signal-detect output for the 2417G4A, and a LVTTL logic level sig­nal-detect output for the 2417H4A.

Absolute Maximum Rat ings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso­lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

Electrostatic Discharge
Caution: This device is susceptible to damage as
a result of electrostatic discharge (ESD). Take proper precautions during both handling and testing. Follow
EIA
dard
Although protection circuitry is designed into the device, take proper precautions to avoid exposure to ESD.
Agere Systems employs a human-body model (HBM) for ESD susceptibility testing and protection-design evaluation. ESD voltage thresholds are dependent on the critical parameters used to define the model. A standard HBM (resistance = 1.5 kΩ, capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM ESD threshold estab­lished for the 2417G4A and 2417H4A transceivers is ±1500 V.

Application Information
The 2417 receiver section is a highly sensitive fiber­optic receiver. Although the data outputs are digital logic levels (LVPECL), the device should be thought of as an analog component. When laying out system application boards, the 2417 tr ansceiv er should receiv e the same type of consideration one would give to a sensitive analog component.
Printed-Wiring Board Layout Consider­ations
A fiber-optic receiver employs a very high gain, wide bandwidth transimpedance amplifier. This amplifier detects and amplifies signals that are only tens of nA in amplitude when the receiver is operating near its sensi ­tivity limit. Any unwanted signal currents that couple into the receiver circuitry cause a decrease in the receiver's sensitivity and can also degrade the perfor­mance of the receiver's signal detect (SD) circuit. To minimize the coupling of unwanted noise into the receiver, careful attention must be given to the printed­wiring board layout.
At a minimum, a double-sided printed-wiring board (PWB) with a large component-side ground plane beneath the transceiver must be used. In applications that include many other high-speed devices, a multi­layer PWB is highly recommended. This permits the placement of power and ground on separate layers, which allows them to be isolated from the signal lines.
Multilayer construction also permits the routing of sen­sitive signal traces away from high-level, high-speed signal lines. To minimize the possibility of coupling noise into the receiver section, high-level, high-speed signals such as transmitter inputs and clock lines should be routed as far away as possible from the receiver pins.
Noise that couples into the receiver through the power supply pins can also degrade performance. It is recommended that the pi filter, shown in Figure 2, be used for both the transmitter and receiver power supplies.
Data and Signal Detect Outputs
The data and signal detect outputs of the 2417 trans­ceiver are driven by open-emitter NPN transistors, which have an outpu t impedance of appr o xima tely 7 Ω. Each output can provide approximately 50 mA maxi­mum current to a 50 load terminated to V
Due to the high switching speeds of ECL outputs, transmission line design must be used to interconnect components. To ensure optimum signal fidelity, both data outputs (RD+/RD–) should be terminated identi­cally. The signal lines connecting the data outputs to the next device should be equal in length and have matched impedances. Controlled impedance stripline or microstrip construction must be used to preserve the quality of the signal into the next component and to minimize reflections bac k int o the receiver, which could degrade its performance. Excessive ringing due to reflections caused by improperly terminated signal lines makes it difficult for the component receiving these signals to decipher the proper logic levels and can cause transitions to occur where none were intended. Also, by minimizing high-frequency ringing, possible EMI problems can be avoided.
The signal-detect output is positive ECL (LVPECL) logic for the 2417G4A and TTL for the 2417H4A. A logic low at this output indicates that the optical signal into the receiver has been interrupted or that the light level has fallen below the minimum signal detect threshold. This output should not be used as an error rate indicator, since its switching threshold is deter­mined only by the magnitude of the incoming optical signal.

Transceiver Processing
When the process plug is placed in the transceiver's optical port, the transceiver and plug can withstand normal wave soldering and aqueous spray cleaning processes. However, the transceiver is not hermetic, and should not be subjected to immersion in cleaning solvents. The transceiver case should not be exposed to temperatures in excess of 125 °C. The transceiver pins can be wave soldered at 250 °C for up to 10 seconds. The process plug should only be used once. After rem ovi ng the process plug fr om the tr ansceiv er, it must not be used again as a pro­cess plug; however, if it has not been contaminated, it can be reused as a dust cover.
