DS90C401M-TI - Dual LVDS Driver | Texas Instruments
부품 번호: DS90C401M-TI ✓ 활성DS90C401M-TI 개요
A low-voltage differential-signaling driver is a line-driver IC that converts a low-voltage logic signal into a balanced differential output. Differential signaling rejects common-mode noise and reduces radiated emissions when the receiver, connector, and transmission-line geometry are handled correctly. In the broader semiconductor hierarchy, an LVDS driver is a physical-layer interface IC within the broader interface-controller category.
The verified manufacturer information identifies the DS90C401 as a dual driver designed for high-data-rate and low-power applications. Its two output channels can work with the DS90C402 receiver to create a complete dual-channel point-to-point LVDS link. The current-mode architecture is significant because it helps limit dissipation as data activity and frequency increase, while the controlled short-circuit behavior helps protect the driver during output faults.
The DS90C401M part is identified by distributor listings as a 2-channel, 2/0 LVDS driver in an 8-SOIC package. The SOIC construction provides a compact surface-mount option for point-to-point links and makes the device suitable for PCB designs that require a conventional small-outline package. Exact voltage, data-rate, differential-output, supply-current, and temperature limits must be confirmed from the manufacturer datasheet before a production design is released.
Typical uses include dual-channel high-speed backplanes, cabinet links, video or control transport between circuit boards, clock distribution, and industrial data acquisition systems. In each case, the device is most useful where two channels can be routed to a compatible DS90C402 receiver and where cable length, connector geometry, and signal-integrity rules are controlled.
A practical design consideration is to treat the differential pair as a controlled-impedance transmission line rather than two independent wires. Keep the two traces closely coupled, provide the receiver termination specified by the manufacturer, minimize stub branches, and confirm the data rate and cable length against the published AC and DC operating limits. This page distinguishes verified product facts from parameters that still require datasheet confirmation.
The information gain here is the combination of verified sourcing links, an honest package and interface classification, drop-in candidate analysis, and design guidance centered on current-mode LVDS behavior. It is intended to help engineers narrow the correct TI device and datasheet review without inventing unavailable electrical ratings or commercial data.

Dual Point-to-Point LVDS Links
The Texas Instruments DS90C401M-TI fits dual point-to-point links because it combines two current-mode LVDS driver channels in one 8-SOIC package. Pairing the device with a compatible DS90C402 receiver creates a balanced two-channel interface for transferring data between circuit assemblies. Its disclosed low-power and high-data-rate optimization is useful when the link must operate continuously without the power behavior associated with a less specialized transmitter. The two outputs can also support independent point-to-point channels, reducing the number of driver packages required on a board. Before release, engineers should verify the supported data rate, supply voltage, input logic levels, and maximum cable length in the manufacturer datasheet.

Industrial Control and Data Acquisition
The DS90C401M-TI can support industrial control or data-acquisition links that carry two channels between a controller and a remote measurement or actuation section. Its two-driver organization fits compact systems where each board-to-board link must transport two independent signals, while the 8-SOIC package simplifies routing into a conventional surface-mount design. Current-mode operation is specifically identified by Texas Instruments as helping keep power dissipation low at high frequency and minimizing short-circuit fault current. An industrial implementation should nevertheless validate common-mode limits, connector behavior, grounding, and the environmental temperature range before using the driver outside its published operating conditions.

Video Transport Interfaces
The DS90C401M-TI is applicable to compact video or synchronized control transport links when the receiving circuitry accepts LVDS and the system complies with the device’s published data-rate and cable-length limits. Two driver channels can carry related video timing or control information over balanced interconnects, where differential signaling can reduce susceptibility to common-mode disturbance compared with single-ended routing. The device’s high-data-rate optimization and low-power current-mode architecture make it a candidate for board-to-board video transport rather than a general-purpose output driver. Signal-integrity review remains essential because skew, impedance discontinuities, connector geometry, and receiver termination can determine whether a nominally differential link performs correctly.

Clock Distribution
The dual output arrangement of the DS90C401M-TI can distribute two related clock or low-speed control signals across a board-to-board interface. Using differential transmission can provide better noise immunity than an unbalanced connection when both ends observe a common ground reference, and the current-mode implementation helps control dissipation as signal activity increases. The 8-SOIC package allows the two outputs to be placed close to a connector or receiver section without requiring two separate driver packages. Engineers should treat each output as a controlled-impedance transmission line, keep the differential pair closely coupled, terminate according to the receiver recommendations, and verify edge-rate and timing requirements from the datasheet.
추천
Backplane and Cabinet Interconnects
The DS90C401M-TI can be evaluated for backplane or cabinet interconnect links where two balanced channels must cross a controlled connection between boards or subsystems. Its low-power current-mode architecture is relevant when many transmit channels operate simultaneously, because the manufacturer highlights low dissipation at high frequency and minimized short-circuit fault current. The dual 8-SOIC implementation reduces component count compared with two separate single-channel drivers. Actual deployment depends on the allowable trace or cable length, signaling rate, connector loss, common-mode range, and receiver performance. A signal-integrity review should include return loss, pair skew, connector transitions, and grounding before the interface is approved for production.

Low-Power High-Speed Data Transport
The DS90C401M-TI is intended for high-data-rate, low-power applications and therefore fits systems in which two differential channels must be transmitted continuously between closely coupled subsystems. The manufacturer’s current-mode design is intended to preserve low power dissipation even at high frequency, a useful characteristic when heat or energy use constrains the transmitter. The 8-SOIC package also provides a compact route for placing the driver near a connector. To realize the intended benefit, use short controlled-impedance traces, maintain consistent differential spacing, avoid unnecessary stubs, and confirm that the receiver, connector, and cable support the selected data rate. The published maximum rate and operating limits must be taken directly from the manufacturer datasheet.

설계 노트
Route each LVDS output as a controlled-impedance differential pair with continuous reference plane, closely matched spacing, and minimized stub length. Avoid changing layer or reference-plane transitions without checking return loss. The verified material does not provide a maximum data rate or cable length, so signal-integrity validation must be based on the manufacturer datasheet and the actual receiver, connector, and PCB stack-up.
Place the device supply-decoupling network directly beside the supply and ground pins, following the Texas Instruments datasheet schematic exactly. Current-mode operation is intended to limit dissipation at high frequency, but activity-dependent power still requires normal supply planning. Confirm the supply tolerance, quiescent current, output-current behavior, and decoupling recommendations because these values are not exposed in the supplied verified excerpts.
Place the DS90C401M-TI near the connector or receiver-facing edge of the board when practical, then keep the differential route short and free of test pads that create impedance discontinuities. Use the datasheet-recommended termination at the receiving end and account for connector and cable loss in the channel budget. Never infer exact pin names from the 8-SOIC outline; verify the authoritative pinout before routing.
Do not substitute a receiver, cross-package device, or merely similar LVDS driver without checking pinout, supply voltage, input thresholds, output voltage, propagation delay, and termination requirements. The verified drop-in candidate DS90C401MX/NOPB has consistent terminals and package according to the comparison source, but ordering-suffix and temperature-grade details still require confirmation before an approved-part change.
규정 준수 정보
The supplied verified excerpts do not extract RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is marked not_applicable because this is a general-purpose interface IC, not an automotive-qualified variant stated in the supplied data.
