DS90LV027MX - Dual 600Mbps LVDS Driver | Texas Instruments
MPN: DS90LV027MX ✓ Hoạt độngDS90LV027MX Tóm tắt
An LVDS driver is a line and bus driver that converts a low-voltage CMOS logic input into a balanced differential output. Because LVDS transmits information as the voltage difference between two conductors, it can support high data rates while reducing sensitivity to common-mode noise and limiting electromagnetic emissions. The DS90LV027MX includes two independent differential drivers, allowing clock, data, control, or serial-interface signals to be transmitted in parallel. Its dual-channel architecture increases routing flexibility while conserving board area compared with two separate single-channel devices.
The manufacturer describes the DS90LV027 as a current-mode driver optimized for high-data-rate and low-power operation. This architecture helps power dissipation remain low as operating frequency increases and also reduces the short-circuit fault current available from the outputs. Differential output swing is typically 340 mV, which supports LVDS-compatible receivers and limits output voltage excursions. The 8-lead SOIC package uses a flow-through layout intended to make PCB layout easier, particularly when traces must pass through or around the device on high-speed digital boards.
The verified device information identifies DS90LV027MX as a 2/0 LVDS driver in an 8-SOIC package. The related lead-free DS90LV027MX/NOPB listing identifies a 3.0 V to 3.6 V supply range, while Mouser lists the commercial-temperature variant at 0°C to 70°C. The DS90LV027 family is designed for data rates in excess of 600 Mbps, equivalent to more than 300 MHz of serialized information according to the family description. The current-mode implementation and controlled differential swing help balance high throughput, power consumption, and EMI control.
Typical uses include clock distribution, parallel-to-serial data links, industrial-control interfaces, test and measurement equipment, video timing links, and communications systems that transmit high-speed clock or data over balanced lines. Because the DS90LV027MX provides two differential outputs, a board designer can use one channel for a clock and another for data, or deploy two independent data streams. In each case, the receiver, cable, connector, and PCB geometry must be designed consistently with LVDS signal integrity requirements.
The most important layout consideration is to preserve controlled differential impedance and minimize the distance over which the two traces of a pair are separated. Place decoupling close to the supply pins, route the differential pair as a tightly coupled pair, and avoid unnecessary stubs or test-point discontinuities. The 8-lead SOIC footprint is easy to source, but package parasitics, connector transitions, and imperfect pair geometry can still reduce the practical benefit of the device’s high supported data rate.
This product page combines the verified Texas Instruments and distributor information with package, application, selection, and design guidance. It also distinguishes confirmed ordering variants from unsupported substitutes and identifies every parameter that still requires confirmation from the manufacturer datasheet or distributor record.

Ứng dụng tiêu biểu
DS90LV027MX phù hợp cho 6 Áp dụngs: High-Speed Clock Distribution, Industrial Control Data Links, Parallel-to-Serial Data Transport, Video Timing Interfaces, Test and Measurement Equipment, Low-Power LVDS Interconnects.
High-Speed Clock Distribution
The DS90LV027MX fits clock distribution because its two current-mode LVDS outputs support rates in excess of 600 Mbps while maintaining low power dissipation at high frequency. A board can route a clock through one differential channel and a complementary or data-related signal through the other. The typical 340 mV differential swing helps limit EMI, while the flow-through 8-lead SOIC arrangement simplifies routing across a balanced clock network. The receiving clock device must support LVDS inputs, and the PCB must maintain controlled differential impedance and closely matched trace lengths.

Industrial Control Data Links
Industrial control equipment can use the DS90LV027MX to transmit two clock or data signals over balanced LVDS connections. Its support for rates above 600 Mbps provides margin for parallel-to-serial data movement, while the current-mode implementation limits high-frequency dissipation and minimizes short-circuit fault current. The 3.0 V to 3.6 V supply range aligns with common 3.3 V control electronics. Designers should still verify receiver thresholds, cable length, grounding, and industrial temperature requirements because the verified DS90LV027MX listing specifies a 0°C to 70°C range.
Được đề xuất
Parallel-to-Serial Data Transport
The DS90LV027MX is suitable for compact parallel-to-serial transport blocks that must move clock and data across a board or through a balanced cable. Its dual-driver organization allows simultaneous transmission of two differential signals without requiring two separate packages. Because the family supports data rates in excess of 600 Mbps, it can serve as the transmit stage in a high-speed link when paired with a compatible LVDS receiver. Practical performance depends on maintaining a tightly coupled trace pair, minimizing stubs, and providing low-impedance return paths in the multilayer PCB.
Được đề xuất
Video Timing Interfaces
Video timing systems can use the DS90LV027MX to carry horizontal or vertical synchronization information and related control signals over LVDS. Differential transmission reduces susceptibility to common-mode noise compared with a single-ended interface, while the driver’s typical 340 mV swing provides a controlled low-EMI output. The two-channel SOIC can support a timing clock and an associated data stream. The video receiver must meet the required pixel-clock rate and the PCB connector transition must preserve differential impedance to avoid reflections and timing degradation.
Được đề xuất
Test and Measurement Equipment
The DS90LV027MX can transmit high-rate clocks or data between instrument subsystems where compact differential drivers are needed. Its dual-channel arrangement reduces the number of packages required when two related signals are routed, and its current-mode outputs are designed to keep dissipation low at high operating frequencies. The 8-SOIC footprint is straightforward to assemble and route. For instrumentation, engineers should evaluate receiver tolerance, cable attenuation, connector geometry, and ground-plane continuity because those factors can determine whether the more-than-600-Mbps capability is usable at the target distance.
Được đề xuất
Low-Power LVDS Interconnects
The DS90LV027MX fits board-to-board or backplane interconnect designs that require balanced signaling without the power cost of a continuously switching driver. The current-mode architecture allows power dissipation to remain low at high frequency, while controlled differential swing helps reduce electromagnetic emissions. Two drivers can be used for complementary clock and data links, or one channel can remain unused if only one link is required. Design validation should include simultaneous-channel activity, fault-current behavior, supply-noise sensitivity, and receiver thresholds across the intended operating range.

Ghi chú thiết kế
Route each LVDS channel as a tightly coupled differential pair with continuous reference planes. Maintain equal trace lengths where timing skew matters, avoid changing layer transitions without corresponding return-path vias, and keep the pair away from switching nodes and unrelated high-current traces. The verified data specifically identifies a flow-through package arrangement for easier PCB layout, but it does not replace impedance calculation or receiver-specific trace-length guidance.
Treat the DS90LV027MX outputs as controlled-impedance differential interfaces rather than ordinary CMOS outputs. Use a receiver whose differential thresholds and input impedance are compatible with the driver, minimize connector and cable transitions, and provide a continuous ground reference. The verified support for rates in excess of 600 Mbps does not guarantee that an arbitrary cable, connector, or PCB route will preserve that rate; validate the complete channel with eye-diagram and compliance measurements.
Place the supply-decoupling capacitor close to the device supply pins and provide a low-impedance plane connection to minimize loop area. The verified supply range is 3.0 V to 3.6 V around a nominal 3.3 V rail. The current-mode architecture is designed to reduce high-frequency dissipation, but total power still depends on supply voltage, output loading, channel activity, and ambient temperature, so rail headroom should be evaluated with the receiver and interconnect load included.
Do not substitute any 8-pin LVDS driver solely because it is also labeled dual or differential. Confirm channel polarity, input thresholds, supply range, package pin assignments, output swing, propagation delay, and temperature grade. The supplied cross-reference evidence confirms three Texas Instruments ordering variants of the DS90LV027 family, but it does not substantiate unrelated competitors as true drop-in replacements for this exact footprint.
