5 / 10 page 5 Shipping Container The data link modules are packaged in a shipping container designed to protect it from mechanical and ESD damage during shipment or storage. Board Layout – Interface Circuit and Layout Guidelines It is important to take care in the layout of your circuit board to achieve optimum performance from these data link modules. Figure 7 provides a good example of a power supply filter circuit that works well with these parts. Also, suggested signal terminations for the Data, Data-bar, Signal Detect and Signal Detect-bar lines are shown. Use of a multilayer, ground-plane printed circuit board will provide good high-frequency circuit performance with a low inductance ground return path. See additional recommendations noted in the interface schematic shown in Figure 7. Figure 7. Recommended interface circuitry and power supply filter circuits. Notes: 1. Resistance is in ohms. Capacitance is in microfarads. Inductance is in microhenries. 2. Terminate transmitter input data and data-bar at the transmitter input pins. Terminate the receiver output data, data-bar, and signal detect-bar at the follow-on device input pins. For lower power dissipation in the signal detect termination circuitry with small compromise to the signal quality, each signal detect output can be loaded with 510 ohms to ground instead of the two resistor, split-load pecl termination shown in this schematic. 3. Make differential signal paths short and of same length with equal termination impedance. 4. Signal traces should be 50 ohms microstrip or stripline transmission lines. Use multilayer, ground-plane printed circuit board for best high- frequency performance. 5. Use high-frequency, monolithic ceramic bypass capacitors and low series DC resistance inductors. Recommend use of surface-mount coil inductors and capacitors. In low noise power supply systems, ferrite bead inductors can be substituted for coil inductors. Locate power supply filter components close to their respective power supply pins. C7 is an optional bypass capacitor for improved, low-frequency noise power supply filter performance. 6. Device ground pins should be directly and individually connected to ground. 7. Caution: do not directly connect the fiber-optic module PECL outputs (data, data-bar, signal detect, signal detect-bar, VBB) to ground without proper current limiting impedance. 8. (*) Optional metal ST optical port transmitter and receiver modules will have pins 8 and 9 electrically connected to the metal port only and not connected to the internal signal ground.
