LVPECL Application Diagrams

Figure 7. Standard PECL Output Conﬁguration Figure 8. Single Resistor Termination Scheme

Figure 9. Pull-Up Pull Down Termination

Resistor values are typically 120 to 240 ohms

for 3.3V operation.

Resistor values are typically 82 to 120 ohms

for 2.5V operation.

Resistor values are typically for 3.3V operation

For 2.5V operation, the resistor to ground is 62

ohms and the resistor to supply is 240 ohms

The VCC6 incorporates a standard PECL output scheme, which are un-terminated emitters as shown in Figure 7. There are numerous application notes on

terminating and interfacing PECL logic and the two most common methods are a single resistor to ground, Figure 8, and a pull-up/pull-down scheme as

shown in Figure 9. An AC coupling capacitor is optional, depending on the application and the input logic requirements of the next stage.

Figure 11. LVDS to LVDS Connection, Internal 100ohm

Some LVDS structures have an internal 100 ohm resistor on the

input and do not need additional components.

Figure 12. LVDS to LVDS Connection

External 100ohm and AC blocking caps

Some input structures may not have an internal 100 ohm

resistor on the input and will need an external 100ohm

resistor for impedance matching. Also, the input may have

an internal DC bias which may not be compatible with

LVDS levels, AC blocking capacitors can be used.

Output Conﬁguration

One of the most important considerations is terminating the Output and Complementary Outputs equally. An unused output should not be left un-termi-

nated, 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.
