Figure 6. Standard PECL Output Configuration Figure 7. Single Resistor Termination Scheme
Resistor values are typically 140 ohms for 3.3V
operation and 84 ohms for 2.5V operation.
Figure 8. Pull-Up Pull Down Termination
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 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.

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.
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 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.

Maximum Ratings, Tape & Reel
S
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 affect 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 define 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.
