Single Resistor Termination Scheme
Figure 10.
Standard HCSL Output Configuration
In some cases a 10-30 ohm series resistor is
used to help reduce overshoot.
The VM-702 incorporates a standard High Speed Current Logic, HCSL ,output scheme which is a 15mA current source switched between Out and Comple-
mentary 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 im-
pedance 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-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.

Figure 11. Single Resistor Termination Scheme
Resistor values are typically 140 ohms for 3.3V operation
and 82.5ohms for 2.5V operation.
Figure 12. 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 250 ohms
The VM-702 incorporates a standard LVPECL output scheme, which are un-terminated emitters as shown in Figure 8. There are numerous application
notes on terminating and interfacing LVPECL logic and the two most common methods are a single resistor to ground, Figure 9, and a pull-up/pull-down
scheme as shown in Figure 10. An AC coupling capacitor is optional, depending on the application and the input logic requirements of the next stage.

Figure 13. LVDS to LVDS Connection, Internal 100ohm
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.
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

IR Compliance
Suggested IR Profile
Devices are built using lead free epoxy and can be subjected to
standard lead free IR reflow conditions shown in Table 6. Contact
pads are gold over nickel and lower maximum temperatures can also
be used, such as 220C.

Maximum Ratings, Tape & Reel
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 VM-702, 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.
