Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. If a cable fault condition occurs that shorts the twisted pair conductors together, thus resulting in a 0V differential input voltage to the receiver, the receiver output will remain in a high state. Typically the characteristic impedance of the media is in the range of X. A current mode driver, generally speaking has a high output impedance and supplies a constant current for a range of loads a voltage mode driver on the other hand supplies a constant voltage for a range of loads. Channel 4 Noninverting Output Current Driver.

The active high and active low enable inputs deactivate all the current drivers when the drivers are in the disabled state.

The received voltage is centered around the receiver offset of 1. Output short circuit current IOS is specified as magnitude only, minus sign indicates lvdx only.

This is a stress rating only; functional operation of the device at these or any other conditions 33v those indicated in the operational section of this specification is not implied. Chip to Chip Skew is defined as the difference between the minimum and maximum specified differential propagation delays. All voltages are referenced to ground unless otherwise specified.

DS90LV 3V LVDS Quad CMOS Differential Line Driver

External lower value pull up and pull down resistors for a stronger bias may be used to boost fail-safe in the presence of higher noise levels. Lab 9 in this note. Do not tie unused receiver inputs to ground or any other voltages. National Semiconductor Corporation Americas Tel: The receiver output will be High for all failsafe conditions. TI bases its knowledge and belief on information provided by third parties, and makes no representation or warranty as to the accuracy of such information.


Samples may or may not be available. LVDS drivers and receivers are intended to be primarily used in an uncomplicated point-to-point configuration as is shown in Figure 6. The data can then be transmitted for considerable distances, over media such as a twisted pair cable or PCB backplane, to an LVDS receiver such as the ADN, where it develops a voltage across a termination resistor, RT. LVDS drivers and receivers are intended to be primarily used in an uncomplicated point-to-point configuration as is shown in Figure 6.

If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. Generator waveform for all tests unless otherwise specified: Point-to-Point Application 5 http: If the cable picks up more than 10mV of differential noise, the receiver may see the noise as a valid signal and switch.

The differential voltage is detected by the receiver and converted back into a single-ended logic signal.

Driver Output Levels http: This specification applies to devices over the recommended operating temperature and voltage ranges, and across process distribution. Life support devices or systems are devices or systems which, a are intended for surgical implant into ovds body, or b support or sustain life, and whose failure to perform, when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user.


The current mode requires as discussed above that a resistive termination be employed to terminate the signal and to complete the loop as shown in Figure 6.

Keep drivers and receivers as close to the LVDS port side connectors as possible.

All typicals are given for: A termination resistor of X should be selected to match the media, and is located as close to the receiver input pins as possible. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

3 V, LVDS, Quad, CMOS Differential Line Driver ADN4665

This can be prevented with minimal impact to the DS90LV AC performance by installing a ccmos pull down resistor on the minus receiver input pin to ground. They should not introduce major impedance discontinuities.

Pin Configuration Table 4. This will help eliminate reflections and ensure noise is coupled as common-mode. The signal is centered around a 1. Within a pair of traces, the distance between the two traces should be minimized to maintain common-mode rejection of the receivers.
