DS90C402M Overview
What is an LVDS receiver? Low Voltage Differential Signaling, or LVDS, is a differential digital interface technology that conveys one bit across two conductors carrying complementary signals. An LVDS receiver detects the voltage difference between those inputs and rejects common-mode noise that appears equally on both conductors. In the broader hierarchy, the DS90C402M is a differential line receiver, interface IC, digital communications component, and semiconductor.
The main verified features are its dual-receiver architecture, ±100 mV input threshold sensitivity, and common-mode noise protection. The device is packaged in a PCB space-saving 8-lead small-outline package identified by distributor listings as SOIC. The receiver is intended for high-data-rate and low-power applications, making it suitable for point-to-point links where low voltage, differential signaling, and noise immunity are important.
The DS90C401 and DS90C402 form a complementary pair-chip solution for dual high-speed point-to-point communication. Using matched differential routing helps preserve signal integrity and reduces susceptibility to external noise. The receiver’s threshold specification also defines the input signal region it recognizes as a valid differential transition, while common-mode protection helps the interface tolerate noise present on both input conductors.
Typical applications include high-speed point-to-point links, low-voltage serial communication, LVDS-compatible backplanes, industrial control links, test equipment interfaces, and embedded systems that use differential digital signaling. The DS90C402M should be selected when the board uses the same eight-pin SOIC footprint and the interface electrical requirements match the verified receiver specifications. The datasheet should be consulted for supply voltage, input common-mode range, propagation delay, and absolute maximum ratings before final design release.
For PCB implementation, keep the differential pair impedance controlled and minimize stubs and unnecessary routing length. Provide a continuous reference plane and terminate unused inputs according to the manufacturer’s guidance. Avoid substituting generic differential receivers without checking pin mapping, supply voltage, threshold behavior, and propagation delay.

Typical Applications
DS90C402M is suitable for 6 applications: High-Speed Point-to-Point LVDS Links, Industrial Control Communication, Test and Measurement Interfaces, Embedded Backplane Communication, Low-Power Data Acquisition Modules, Data and Control Links in Robotics.
High-Speed Point-to-Point LVDS Links
The DS90C402M fits high-speed point-to-point links because it combines two receivers with ±100 mV threshold sensitivity and common-mode noise protection. It can receive two differential channels in an 8-SOIC package, allowing a compact interface between two nearby assemblies. When paired with the DS90C401 transmitter, it supports the manufacturer-described dual high-speed point-to-point solution. The design must preserve controlled differential impedance and verify supply, timing, and termination requirements from the datasheet.
Recommended
Industrial Control Communication
The DS90C402M can serve as the receiving element for industrial control signals where differential signaling helps reject common-mode noise. Its dual-channel architecture supports two independent receiver paths, while the ±100 mV threshold sensitivity provides a defined input detection range. Use it only when the controller’s logic levels, cable length, grounding strategy, and link timing are compatible with the verified LVDS interface. Industrial qualification status and extended temperature requirements should be checked separately.
Recommended
Test and Measurement Interfaces
The DS90C402M is suitable for compact test and measurement equipment that needs noise-tolerant differential reception across short point-to-point links. Two receivers can reduce the number of external receiver packages, while common-mode protection helps the interface tolerate coupled noise in an instrument enclosure. The 8-SOIC footprint simplifies board-level integration, but the system designer must verify input common-mode limits, propagation delay, supply voltage, and termination values before release.
Recommended
Embedded Backplane Communication
The DS90C402M can be used in embedded backplanes where LVDS differential signaling is used to carry data between circuit cards or tightly spaced subsystems. The dual receiver provides two channels in one package, and common-mode noise protection is valuable when multiple digital domains share a connector or chassis. Board layout must maintain a continuous reference plane, appropriate differential impedance, and short return paths. Cable length and data-rate limits must be established from the full manufacturer documentation because they are not present in the supplied snippets.
Recommended
Low-Power Data Acquisition Modules
The DS90C402M is appropriate for low-power data-acquisition modules that need to receive differential control or data signals without adding a large transceiver package. Its two-receiver configuration can handle paired links while the low-power design objective supports compact systems. The selected board should provide local decoupling and a stable ground reference, and the differential pair should be routed with matched geometry. Confirm supply-current and operating-temperature values in the datasheet before using it in a temperature- or battery-constrained design.
Recommended
Data and Control Links in Robotics
The DS90C402M can support differential data or control links in robotics systems where motor, actuator, and sensor wiring may introduce noise. Common-mode noise protection and ±100 mV threshold sensitivity help distinguish the intended differential signal, while dual reception supports compact multi-channel interfaces. The design should keep the receiver close to the protected logic section, maintain controlled impedance, and use connector and cable practices appropriate for the environment. Verify that the robot controller’s LVDS levels and timing match the receiver before deployment.

Design Notes
Route each LVDS pair as a controlled-impedance differential line over a continuous reference plane. Keep the positive and negative traces closely coupled, match their length as practical, and minimize vias, stubs, and test-pad discontinuities. The verified DS90C402M data confirms ±100 mV threshold sensitivity and common-mode noise protection, but the actual signal-integrity margin still depends on the complete transmitter, cable, termination, and receiver specifications.
Use the manufacturer’s 8-SOIC footprint and pin assignment rather than inferring functions from package size. Confirm differential inputs, supply, ground, and enable or output connections from the official DS90C402 datasheet. Place local bypass capacitors close to the device’s supply pins and provide an uninterrupted ground connection. Because the supplied snippets do not include the complete pinout or recommended capacitor values, do not fabricate those values during schematic capture.
Do not treat every 8-pin differential receiver as a direct DS90C402M substitute. The candidate must match the receiver topology, pin mapping, supply voltage, input threshold, propagation delay, common-mode range, and termination expectations. Also verify that a companion transmitter’s output amplitude and edge rate are compatible with the receiver’s ±100 mV threshold specification. A cross-reference search result alone is not sufficient evidence for production substitution.
Compliance Information
The supplied verified results do not provide compliance statements for DS90C402M. Confirm RoHS, REACH, lead-free, halogen-free, conflict-minerals, and automotive qualification status using the current manufacturer product documentation or supplier declaration.
