Stan-
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 1417K5A transceiver is ±1000 V.
Application Information
The 1417 receiver section is a highly sensitive fiber­optic receiver. Although the data outputs are digital logic levels (CML), the device should be thought of as an analog component. When laying out system appli­cation boards, the 1417 transceiver should receive the same type of consideration typicall y given t o a sensitiv e analog component.
Printed-Wiring Board Layout Consider­ations
A fiber-optic receiver employs a very high gain, wide­bandwidth transimpedance amplifier. This amplifier detects and amplifies signals that are only tens of nA in amplitude when the receiver is operating near its sensi­tivity 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.
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 a pi filter, shown in Figure 4, be used for both the transmitter and receiver power supplies.
Data, Clock, and Signal Detect Outputs
Due to the high switching speeds of CML outputs, transmission line design must be used to interconnect components. To ensure optimum signal fidelity, both data outputs should be terminated identically. The sig­nal lines connecting the data outputs to the ne xt 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 back into 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 was intended. Also, by mini­mizing high-frequency ringing, possible EMI problems can be avoided.
The signal-detect output is positiv e LVTTL logic. 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 removing the process plug from the transceiver, 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.
