DS90C402MX - Dual 155.5Mbps LVDS Receiver | Texas Instruments
MPN： DS90C402MX ✓ 啟用中DS90C402MX 概覽
An LVDS receiver is an interface IC that detects a small differential voltage between two conductors and converts that signal into a compatible digital logic output. This differential method belongs to the broader interface-IC and signal-conditioning hierarchy. Compared with single-ended links, differential reception can improve noise immunity by rejecting common-mode disturbance. The DS90C402MX is intended for one half of a dual high-speed link when paired with the Texas Instruments DS90C401.
Key features include two independent LVDS receivers, operation to 155.5 Mbps, ±100 mV threshold sensitivity, and common-mode noise protection. Its low-power design targets systems where receiver power and board area are constrained. The dual architecture consolidates two receive channels into one package, reducing component count compared with two separate single-channel receivers. The exact supply current, input capacitance, propagation delay, output timing, and connector details are not present in the supplied verified data and therefore are not inferred here.
The receiver’s differential inputs are intended for point-to-point communication, where a complementary transmitter establishes the proper signal and termination environment. Its common-mode protection is especially relevant when traces share a board with digital or switching circuitry. Engineers must nevertheless preserve the differential geometry recommended by the manufacturer datasheet and control impedance consistently from transmitter through receiver. A receiver alone does not create a compliant LVDS link; the transmitter, cable or PCB transmission medium, termination, connector, and system grounding all affect signal integrity.
Typical applications include dual-channel point-to-point backplanes, industrial control links, embedded instrumentation, and compact communications equipment. The DS90C401/DS90C402 pairing supports two coordinated high-speed channels where a single-channel LVDS receiver would require duplicated packages. In data converters or digital processing systems, the receiver can also recover signals arriving from a remote circuit board when the board-level channel has already been characterized.
The primary design consideration is preserving LVDS signal integrity through controlled-impedance, tightly coupled routing and correct termination. Review the complete manufacturer datasheet for electrical tables, recommended land patterns, input topology, and timing before release because several detailed values are unavailable in the verified excerpts. For pricing and replacement decisions, do not assume that a functional transceiver or driver is pin compatible; the receiver must match the existing footprint, supply arrangement, and pinout.
This page combines the verified manufacturer descriptions, package identification, operating-rate reference, threshold sensitivity, and replacement search results into an engineering-oriented DS90C402MX overview. It distinguishes verified facts from parameters that require the full datasheet and avoids presenting unverified electrical, compliance, lifecycle, or pricing claims as established specifications.

典型應用
DS90C402MX 適用於 6 應用s: Dual Point-to-Point LVDS Link, Industrial Control Backplane, Embedded Instrumentation Interface, Data Converter Interconnect, Board-to-Board Communication, Synchronized Measurement Channel.
Dual Point-to-Point LVDS Link
DS90C402MX fits a dual point-to-point link when the system uses two LVDS receive channels and a compatible transmitter such as the DS90C401. Its verified signaling-rate capability is 155.5 Mbps, while ±100 mV threshold sensitivity provides the specified detection margin for differential signals. The receiver is placed at the receiving end of each controlled-impedance channel, with board routing and termination selected from the complete DS90C401/DS90C402 implementation guidance. Because the two channels are integrated in one 8-SOIC package, the design can reduce board area compared with separate single-channel receivers, while common-mode noise protection helps reject disturbance that appears equally on both conductors.
推薦
Industrial Control Backplane
DS90C402MX is suitable for an industrial control backplane where two low-power differential channels must carry data between circuit boards or control modules. The verified 5 V supply and -40 °C to +85 °C temperature range provide the primary environmental framework for this use, while 155.5 Mbps supports high-rate point-to-point communication. Differential routing is important in industrial systems because switching regulators, motors, and digital logic can create common-mode noise; the receiver’s documented common-mode protection helps the link remain usable. The final design must still verify connector loss, grounding, cable length, termination, and the receiver timing limits in the manufacturer datasheet.
推薦
Embedded Instrumentation Interface
DS90C402MX can receive two low-voltage differential data streams in embedded instrumentation that separates a transmitter module from a processing or conversion section. At up to 155.5 Mbps, the verified device rate provides a practical interface for transferring synchronized or parallelized channel data across a short board-to-board connection. Its low-power optimization helps preserve system budget, and the two-channel package reduces the number of receiver footprints. Engineers should preserve pair symmetry, maintain a continuous reference plane, and avoid routing the LVDS pairs beside unrelated high-current switching nodes. The complete timing and input-parameter tables are required before defining timing margins.
推薦
Data Converter Interconnect
DS90C402MX can serve as the receive element in a data-converter interconnect when the surrounding system requires two low-noise differential links rather than a single-ended connection. The verified receiver threshold of ±100 mV establishes the input sensitivity reference, and the common-mode protection feature is useful when the converter subsystem shares a board with high-energy digital or switching circuits. The part is intended to pair with the DS90C401 in a dual high-speed point-to-point solution. Actual suitability depends on the converter’s output timing, link distance, termination strategy, jitter budget, and the DS90C402MX electrical tables, none of which are fully present in the supplied excerpts.
推薦
Board-to-Board Communication
DS90C402MX is appropriate for short, point-to-point board-to-board communication when both boards share compatible power and ground conventions and the transmission medium can be controlled. Its 8-SOIC package and two receive channels make it a practical consolidation point for dual-link designs, while the verified 155.5 Mbps rate supports relatively high-speed transfer over suitable interconnects. Differential pair geometry, impedance, return-path continuity, and connector transitions must be treated as part of the receiver design because a correct receiver pinout alone cannot compensate for poor channel implementation. The exact package land pattern and recommended terminations should be copied from the official manufacturer documentation.
推薦
Synchronized Measurement Channel
DS90C402MX can receive two synchronized measurement-data channels in a compact acquisition or control system. The dual architecture is useful when related samples must arrive through matched differential paths and the system must preserve channel-to-channel symmetry. The documented ±100 mV threshold sensitivity provides the receiver’s specified decision threshold, and common-mode protection helps reject noise coupled equally onto each pair. The design should maintain matched routing and provide a continuous ground reference to prevent differential-to-common-mode conversion. Engineers must confirm propagation delay, output timing, input capacitance, and allowable loading from the full datasheet before using the receiver in a precision timing chain.

- Common-mode noise protection (對比DS90C402MX/NOPB)
設計說明
Route each LVDS pair as a tightly coupled differential pair with a continuous reference-plane return path. Preserve pair symmetry through connectors and layer transitions, and use the DS90C402/DS90C401 system guidance for controlled impedance and termination. The verified material confirms ±100 mV threshold sensitivity and common-mode noise protection, but it does not provide a recommended trace impedance or termination value; obtain those values from the full manufacturer datasheet before release.
Place the DS90C402MX close to the receiving connector or channel endpoint and keep the receiver pins and surrounding return path free of unrelated high-current switching nodes. The 8-SOIC footprint reduces package count for dual receive channels, but the two pairs should be routed with equivalent geometry and comparable loading. Verify the exact land pattern and exposed thermal or lead geometry against the official package drawing rather than relying on distributor package labels.
Do not substitute a DS90C401 transmitter, an unrelated transceiver, or a component with only a similar data rate for DS90C402MX. A valid drop-in replacement must match the receiver pinout, 8-SOIC footprint, 5 V supply arrangement, differential input behavior, output logic, timing, and common-mode limitations. Also do not treat a distributor page as proof of current stock or guaranteed lead time; confirm the exact MPN and quantity before purchasing.
