LVPECL Application Diagrams
Figure 6. Standard PECL Output Conguration Figure 7. Single Resistor Termination Scheme Figure 8. Pull-Up Pull Down Termination
Resistor values are typically 140 ohms for 3.3V
operation and 84 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
140Ω140Ω
The VCC6 incorporates a standard PECL output scheme, which are un-terminated emitters as shown in Figure 6. There are numerous application notes on
terminating and interfacing PECL logic and the two most common methods are a single resistor to ground, Figure 7, and a pull-up/pull-down scheme as
shown in Figure 8. An AC coupling capacitor is optional, depending on the application and the input logic requirements of the next stage.

Figure 10. LVDS to LVDS Connection, Internal 100ohm Figure 11. LVDS to LVDS Connection
External 100ohm and AC blocking caps
Some LVDS structures have an internal 100 ohm resistor
on the input and do not need additional components. 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.
LVDS Application Diagrams
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 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.

Absolute Maximum Ratings and Handling Precautions
Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied or any other
excess of conditions represented in the operational sections of this data sheet. Exposure to absolute maximum ratings for extended
periods may adversely aect device reliability.
Although ESD protection circuitry has been designed into the VCC6, proper precautions should be taken when handling and mounting.
VI employs a Human Body Model and Charged Device Model for ESD susceptibility testing and design evaluation.
ESD thresholds are dependent on the circuit parameters used to dene the model. Although no industry standard has been adopted for
the CDM a standard resistance of 1.5kOhms and capacitance of 100pF is widely used and therefor can be used for comparison purposes.
