In some cases a 10-30 ohm series resistor is used to help reduce overshoot. The VC-709 incorporates a standard High Speed Current Logic, HCSL ,output scheme which is a 15mA current source switched between Out and Complementary Out. Being un-terminated drains, as shown in Figure 8, they require external 50 ohm resistors to ground as shown in Figure 9. HCSL is a high impedance output with quick switching times, in can be advantageous to use a 10 to 30 ohm series resistor as shown in Figure 10, to help reduce overshoot/ ringing. 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.

Single Resistor Termination Scheme Resistor values are typically 140 ohms for 3.3V operation and 84 ohms for 2.5V operation. Figure 12. Pull-Up Pull Down Termination Resistor values shown are typical for 3.3 V opertaion. For 2.5V operation, the resistor to ground is 62 ohms and the resistor to supply is 250 ohms The VC-709 incorporates a standard PECL output scheme, which are un-terminated FET drains. There are numerous application notes on terminating and interfacing PECL logic and the two most common methods are a single resistor to ground, Figure 11, or for best 50 ohm matching a pull-up/pull-down scheme as shown in Figure 12 should be used. AC coupling capacitor are 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.

LVDS to LVDS Connection, Internal 100ohm Resistor Some LVDS structures have an internal 100 ohm resistor on the input and do not need additional components. AC blocking capacitors can be used if the DC levels are incompatible. LVDS Driver 100ȍ Receiver Figure 14. LVDS to LVDS Connection 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.

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 VC-709, 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. Table 7.
