There are numerous application notes on terminating and interfacing PECL logic and the two most common methods are a single resistor to ground, Figure 4, and a pull-up/pull-down scheme as shown in Figure 5. An AC coupling capacitor is optional, depending on the application and the input logic requirements of the next stage. One of the most important considerations is terminating the Output and Complementary Outputs equally. An unused output should not be left un-terminated, and if it one of the two outputs is left open it will result in excessive jitter on both. PC board layout must take this and 50 ohm impedance matching into account. Load matching and power supply noise are the main contributors to jitter related problems. Figure 3 Standard PECL Output Configuration Figure 4 Single Resistor Termination Scheme Resistor values are typically 120 to 240 ohms Figure 5 Pull-Up Pull-Down Termination Reliability VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The VS-702 family is capable of meeting the following qualification tests: Table 3.

Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this datasheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Permanent damage is also possible if OD or Vc is applied before Vcc. Table 4.
