DS90LV027AHM - 600Mbps Dual LVDS Driver | TI
N.º de pieza: DS90LV027AHM ✓ ActivoDS90LV027AHM Descripción general
An LVDS driver is a line-driver interface that converts low-voltage digital signals into a differential low-voltage signal for reliable, high-speed transmission over balanced interconnects. Within the signal-chain hierarchy, the DS90LV027AHM belongs to the LVDS interface-driver category, uses Low Voltage Differential Signaling, and provides a current-mode differential output suitable for clock and data links.
The device’s key features include support for data rates above 600 Mbps, a typical output swing of 360 mV, and low differential output swing for reduced EMI. Its flow-through pin arrangement simplifies PCB routing by allowing signals to pass through the device without changing direction. The driver architecture also provides short-circuit fault-current limiting, supporting fault-tolerant operation in cables and connectorized backplanes.
Two independent differential outputs allow one package to drive two LVDS channels, reducing board area for parallel clock and data links. Because the outputs are current-mode devices, their power consumption remains low at high operating frequencies. The 3 V to 3.6 V supply range integrates directly with common low-voltage digital systems, while the high-temperature rating supports applications with extended ambient-temperature requirements.
Typical uses include clock distribution, high-speed data transmission, industrial control links, test equipment, backplanes, and industrial systems requiring more than 600 Mbps operation. The DS90LV027AHM can be paired with the DS90LV028AH dual line receiver to form a complete differential transmission path when signal integrity and protocol requirements are compatible.
PCB implementation should preserve the flow-through signal path, use a continuous ground reference plane, and minimize stubs on differential traces. Keep the input and output branches short, maintain closely matched trace geometry, and follow the manufacturer’s recommended supply bypassing and controlled-impedance layout practices.
This page combines the manufacturer’s device characteristics, verified part identification, package information, practical interface-design guidance, and a strict assessment of drop-in replacement options to support faster engineering selection and sourcing.

Aplicaciones típicas
DS90LV027AHM es adecuado para 6 aplicacións: High-Speed Clock Distribution, Industrial High-Speed Data Links, Test and Measurement Equipment, Backplane and Cable Interconnects, Parallel Data Transmission, High-Temperature Control Systems.
High-Speed Clock Distribution
The DS90LV027AHM fits clock-distribution networks requiring low-EMI, high-speed differential outputs. According to the TI manufacturer datasheet, the device supports data rates in excess of 600 Mbps (300 MHz), so it can carry clock signals well beyond 300 MHz. Its two current-mode LVDS outputs support dual-channel distribution while maintaining low power dissipation at high frequency. The flow-through arrangement permits a straight-through PCB signal path, which simplifies controlled-impedance routing and reduces unnecessary trace turns.
Recomendado
Industrial High-Speed Data Links
The DS90LV027AHM is appropriate for industrial data links that need two differential channels, low output swing, and an extended -40°C to +125°C operating specification. Its current-mode LVDS outputs support rates above 600 Mbps (300 MHz), making the device suitable for high-rate command, measurement, or synchronization links. The typical 360 mV differential swing reduces EMI compared with larger-amplitude single-ended signaling. Use continuous reference planes, matched trace geometry, and short branches to preserve signal integrity.
Recomendado
Test and Measurement Equipment
The DS90LV027AHM can drive clock and data connections inside high-speed test and measurement equipment when the interface must operate beyond 600 Mbps (300 MHz). Two independent outputs reduce the driver count required for parallel links, while the current-mode architecture keeps high-frequency power dissipation low. Its 3 V to 3.6 V operating range aligns with conventional low-voltage digital test systems. The flow-through layout helps designers preserve short, balanced paths between the driver and receiver devices.
Recomendado
Backplane and Cable Interconnects
The DS90LV027AHM is suitable for balanced backplane or cable-based LVDS interconnects requiring low EMI and high data throughput. According to the TI manufacturer datasheet, the current-mode outputs support rates above 600 Mbps (300 MHz), and the typical differential output swing is 360 mV. Short-circuit fault-current limiting adds resilience for cable and connector faults. PCB implementation should use a continuous ground plane, matched pair routing, minimal stubs, and termination consistent with the selected LVDS system architecture.
Recomendado
Parallel Data Transmission
The DS90LV027AHM can support parallel data transmission by driving two differential lanes from one 8-pin SOIC package. Its support for data rates in excess of 600 Mbps (300 MHz) provides margin for high-speed source-synchronous or clock-linked data paths. Current-mode operation reduces power dissipation at high frequency, while the flow-through pin arrangement helps maintain a direct PCB route. The design must still account for pair skew, receiver thresholds, connector loss, and the propagation characteristics of the complete interconnect.
Recomendado
High-Temperature Control Systems
The DS90LV027AHM fits high-temperature control or monitoring systems where internal electronics may operate across the -40°C to +125°C range. Its dual current-mode LVDS outputs provide high-speed data transfer without the high-frequency power increase associated with less efficient driver approaches. The 3 V to 3.6 V supply range supports low-voltage digital control electronics. Thermal qualification should apply to the complete assembly, including the PCB, connector, receiver, and power source, because the driver rating alone does not establish system-level thermal performance.

Notas de diseño
Route each differential pair as a tightly coupled, impedance-controlled trace over a continuous ground plane. Keep the flow-through path straight, match the spacing and width of both conductors, and avoid vias where practical. The 360 mV typical output swing and low-EMI design depend on a controlled transmission environment; excessive stubs, unequal pair lengths, or a split ground plane can increase reflections and radiated noise.
Place the driver close to the signal source and receiver to minimize trace loss and preserve the intended high-speed edge rate. Follow the decoupling network and pin placement specified in the manufacturer data sheet, and provide a low-impedance return path beneath every differential pair. Keep test points short and symmetric because an unterminated stub on a >600 Mbps link can act as an unintended antenna or reflection point.
Do not treat an LVDS protocol label or an 8-pin SOIC outline as proof of drop-in compatibility. Verify pin names, supply tolerances, differential output swing, propagation delay, temperature grade, and fault behavior for every proposed substitute. The DS90LV027AHM is the +125°C high-temperature member, so replacing it with a standard-temperature device can reduce environmental margin even when the footprint appears identical.
Use the low 360 mV typical differential output swing to limit edge-driven emissions, but do not assume the IC alone controls EMI. Connector transitions, return-path discontinuities, and cable-radiated noise can dominate the system result. Maintain a continuous reference plane, avoid crossing split-plane boundaries, and use the intended LVDS receiver and termination arrangement to suppress reflected energy at the far end of the link.
