DS90C401M - Dual LVDS Driver | Texas Instruments
MPN: DS90C401M ✗ پایان تولیدDS90C401M نمای کلی
An LVDS driver is a differential-signaling interface IC that transmits information through two conductors carrying complementary signals. The small voltage swing reduces electromagnetic emissions while the differential receiver detects the voltage difference between the conductors. In the broader hierarchy, an LVDS driver belongs to the line-driver and interface-IC category and supports balanced, high-speed communication over printed-circuit-board traces and other suitable point-to-point interconnects.
The DS90C401M is specifically described as a dual device for high-data-rate and low-power applications. Its current-mode architecture helps keep power dissipation low even at high frequency and limits fault current during short-circuit conditions. These characteristics are important where data throughput must be maintained without allowing interface noise, excessive power, or fault energy to disrupt the linked circuitry. The manufacturer also presents the DS90C401 and DS90C402 as a complementary chip solution.
Typical communication links can place the DS90C401M at the transmitting end and a suitable DS90C402 receiver at the receiving end. Differential routing should preserve the conductor geometry and provide a continuous return path beneath or alongside the pair. Because LVDS performance depends on the complete transmission system, cable length, termination, connector geometry, trace impedance, and receiver characteristics must be evaluated together rather than treating the IC in isolation.
A key design consideration is maintaining a low-noise power and ground environment. Decoupling capacitors should be positioned close to the supply and ground pins, while differential traces should be routed as a balanced pair with consistent spacing and minimal stubs. The 8-lead package is suitable for conventional surface-mount assembly, but pin assignments, exposed thermal requirements, and process details should be confirmed from the manufacturer datasheet before layout release.
This page consolidates verified manufacturer descriptions, distributor links, and the identified complementary-interface relationship. It also distinguishes confirmed facts from parameters not supplied by the verified data, avoiding unsupported claims while providing an engineering starting point for DS90C401M selection, sourcing, and circuit design.

کاربردهای معمول
DS90C401M مناسب است برای 6 کاربردs: High-Speed Point-to-Point Data Link, Dual-Channel Differential Interface, Low-Power Serial Communication, EMI-Sensitive Backplane Connection, Industrial Data Acquisition, Test and Measurement Link.
High-Speed Point-to-Point Data Link
The DS90C401M fits the transmit side of a high-speed point-to-point link because it provides two differential driver outputs and a typically 340 mV output swing. Pair it with the manufacturer-identified DS90C402 receiver to establish the receiving function. Its current-mode architecture is intended to keep dissipation low at high frequency, while minimized short-circuit current helps constrain fault energy. The exact supported data rate and trace-length limit must be taken from the full manufacturer datasheet because they are not included in the supplied search evidence.
پیشنهادی
Dual-Channel Differential Interface
The DS90C401M can transmit two differential channels where point-to-point, low-EMI signaling is required. Its dual-driver organization reduces the number of separate transmit devices needed for a two-channel interface, while the low output swing supports cleaner board-level communication. Layout should preserve pair symmetry and provide an adequate return path. Confirm that both channels operate within the complete DS90C401/DS90C402 system's verified speed and distance limits before finalizing the PCB.
پیشنهادی
Low-Power Serial Communication
The DS90C401M is suitable for low-power serial communication tasks that benefit from a current-mode driver rather than large single-ended swings. The manufacturer explicitly describes the device as optimized for both high data rate and low power, and says its dissipation can remain low even at high frequency. This makes it relevant to compact control, test, or data-acquisition systems, provided that trace length, receiver loading, and power-supply noise satisfy the complete interface specification.
پیشنهادی
EMI-Sensitive Backplane Connection
The DS90C401M's differential architecture and typically 340 mV output swing support low-EMI communication over suitable point-to-point interconnects. It can therefore be considered for backplane links where reducing conducted and radiated emissions is important. Real deployment requires controlled impedance, matched pair routing, appropriate terminations at the receiver, and connector qualification. Since the supplied sources provide no distance, impedance, or connector limits, those values must not be assumed from the generic LVDS label.
پیشنهادی
Industrial Data Acquisition
The DS90C401M can serve as the transmitter in an industrial data-acquisition chain when the receiving electronics require a balanced, high-speed interface. Two driver outputs allow the device to support a compact dual-channel transfer between a controller or converter and a remote acquisition section. Its low-dissipation current-mode design is useful where sustained activity must remain power-conscious, while minimized fault current improves robustness. Industrial temperature, isolation, EMC, and creepage requirements still need separate verification because they are not quantified in the supplied data.
پیشنهادی
Test and Measurement Link
The DS90C401M can transmit high-rate data from an instrumentation or test module to another circuit through a balanced point-to-point connection. The manufacturer identifies the device as optimized for high data rates, while the low typical 340 mV swing helps limit EMI in dense test systems. Use symmetric routing and a continuous reference plane to preserve signal quality. Maximum clock rate, jitter, and channel skew are not present in the retrieved source text and must be verified before clocking or sampling requirements are finalized.

یادداشت‌های طراحی
Route each differential output as a matched pair with constant geometry and avoid branches or test pads that create uncontrolled stubs. The verified source does not provide a target impedance, so use the DS90C401/DS90C402 interface specification to select trace dimensions and receiver termination. Preserve a continuous return path beneath or alongside the pair to limit radiated emissions and maintain signal integrity at high data rates.
Keep the driver close to the source-side interface and provide local decoupling at its supply pins. The verified description says current-mode operation keeps dissipation low even at high frequency and limits short-circuit fault current, but it does not provide supply voltage, quiescent current, or capacitor values. Consult the complete manufacturer datasheet before calculating decoupling or power-supply headroom.
Do not substitute the DS90C401 solely because a part is described as an LVDS driver. Confirm the exact 8-pin footprint, pin mapping, supply range, data-rate limit, output polarity, receiver compatibility, and lifecycle status. The verified replacement evidence supports DS90C401 ordering variants, but generic cross-reference tools alone do not establish drop-in compatibility for an unlisted competitor.
