DS90LV019 - 3.3V/5V LVDS Driver Receiver | Texas Instruments
MPN: DS90LV019 ✓ सक्रियDS90LV019 अवलोकन
The DS90LV019 operates from a single 3.3V or 5.0V supply, making it suitable for systems that need a compact differential interface without a separate supply rail for each side of the link. The integrated driver and receiver simplify board-level LVDS connectivity between a controller, FPGA, serializer, or external equipment. The flow-through pin arrangement supports practical PCB routing, including short stubs between device pins and a connector.
The electrical interface is intended for high-speed, low-power differential signaling rather than ordinary single-ended logic. The driver generates the differential output used to overcome noise and common-mode interference over a point-to-point cable or PCB trace, while the receiver converts the differential signal back into a TTL/CMOS-compatible output. The receiver enable input can place the output in a controlled state when the link is not active.
The DS90LV019 is identified as a 14-pin SOIC narrow or 14-pin TSSOP device depending on the ordering variant. The device family is also associated with a military-qualified ordering option, DS90LV019-MIL, for applications requiring that specified product grade. Designers should confirm the exact package, supply requirement, and control-signal polarity in the manufacturer datasheet before layout release.
Typical uses include industrial control links, test and measurement equipment, communication modules, video or imaging interfaces, and embedded systems that need reliable differential signaling over a short interconnect. The independent DE and RE# controls also make the device useful for half-duplex point-to-point links where transmit and receive states must be sequenced.
Design emphasis should be placed on controlled-impedance routing of the differential pair, keeping the driver and receiver connections short, and placing decoupling close to the supply pins. Because the device combines a transmitter and receiver, unused logic inputs should be tied to defined levels rather than left floating. The exact pin assignment, recommended termination network, and maximum signal-rate values must be taken from the manufacturer datasheet for the selected package and grade.

सामान्य अनुप्रयोग
DS90LV019 के लिए उपयुक्त है 6 अनुप्रयोगs: Industrial Point-to-Point Control Links, FPGA and Processor Differential Interfaces, Bidirectional Communication Modules, Test and Measurement Equipment, Video and Imaging Data Interfaces, LVDS-to-TTL Interface Conversion.
Industrial Point-to-Point Control Links
The DS90LV019 fits short industrial control links that need differential signaling between a controller and remote electronics. Its one differential driver and one receiver support a compact bidirectional point-to-point connection, while the independent DE and RE# inputs allow transmit and receive activity to be controlled separately. Operation from a single 3.3V or 5.0V supply simplifies rail selection in systems that already use either voltage. The flow-through pin arrangement also helps engineers route the interface toward a connector with limited board area.
अनुशंसित
FPGA and Processor Differential Interfaces
The DS90LV019 is suitable as an LVDS interface between an FPGA or processor-based module and a high-speed external circuit. The device provides a differential line driver, a differential receiver, and TTL/CMOS-compatible D IN and R OUT logic, which keeps the digital-side interface simple. The 3.3V or 5.0V supply flexibility supports logic levels commonly used by embedded systems. Use controlled-impedance routing and confirm the maximum signaling rate in the manufacturer datasheet for the intended data path.
अनुशंसित
Bidirectional Communication Modules
The DS90LV019 can be used in communication modules where each board connects to another node over a short point-to-point cable. Combining a driver and receiver in one device reduces the number of separate interface components required for a link. Separate DE and RE# controls provide a straightforward way to enable transmit and receive paths independently, and the device accepts a single 3.3V or 5.0V supply. Cable length, connector pinout, and termination must be designed against the applicable signal-rate limits.
अनुशंसित
Test and Measurement Equipment
The DS90LV019 is appropriate for test and measurement equipment that exchanges data over a short differential connection to an instrument module or fixture. The differential driver improves signal integrity over a point-to-point interconnect, and the receiver provides a TTL/CMOS-compatible output for the rest of the instrument. A single 3.3V or 5.0V supply reduces the number of rails required around the interface. Its flow-through pinout supports straightforward routing toward front-panel or board-to-board connectors.
अनुशंसित
Video and Imaging Data Interfaces
The DS90LV019 can support short differential data links in video or imaging modules where a controller must exchange multi-bit information with a remote capture or processing board. The integrated differential driver and receiver keep the interface compact, and the D IN, DE, RE#, and R OUT lines provide straightforward control over both directions. The DS90LV019 supports both 3.3V and 5.0V supplies, helping it fit imaging boards with different logic rails. Signal-rate and lane-timing requirements must be checked in the manufacturer datasheet.
अनुशंसित
LVDS-to-TTL Interface Conversion
The DS90LV019 is useful when one side of a system requires an LVDS differential interface while the local logic side uses TTL/CMOS signals. The differential driver converts D IN into a point-to-point LVDS output, and the receiver converts the incoming differential pair into R OUT. Because the driver and receiver are independent, DE and RE# can be managed separately when only one direction is active. Both 3.3V and 5.0V operation are supported, allowing the interface to fit multiple embedded logic platforms.

डिज़ाइन नोट्स
Route the differential pair as a controlled-impedance transmission line and keep the driver and receiver connections as short as practical. The DS90LV019 uses a flow-through pin arrangement to simplify routing toward a connector, but the differential pair should remain continuous with minimal stubs. Confirm the exact package pinout for the ordered suffix before assigning PCB tracks.
Do not leave unused digital inputs floating. DE, RE#, and D IN should be connected to defined logic levels or controlled by the host logic, while R OUT should be left unconnected only when the receiver output is intentionally unused. Because the driver and receiver are independent, incorrect enable sequencing can place the interface into an unintended state during power-up or link switching.
Use the termination and receiver network specified in the manufacturer datasheet for the intended data rate and interconnect. LVDS performance depends on controlled impedance, proper pair geometry, and correctly placed termination; adding or moving termination components can change the edge response. Validate the completed link with an eye diagram or equivalent signal-integrity measurement when the link distance or rate is substantial.
Place the supply-decoupling capacitor close to the device power pins and keep the return path continuous. The DS90LV019 supports both 3.3V and 5.0V single-supply operation, so the decoupling value and routing should be selected against the operating condition and the datasheet's recommended application circuit. Confirm the absolute maximum and recommended supply ranges for the exact ordering variant.
