DS90C031TM 개요
An LVDS line driver is a differential interface circuit that launches two complementary, low-voltage signals through a balanced conductor pair. The receiving endpoint detects the voltage difference while rejecting common-mode noise. Within the broader hierarchy, LVDS signaling belongs to differential digital interfaces and interface ICs; a line driver converts a logic-level source into a physically suitable low-voltage differential signal for balanced cable or PCB links.
The DS90C031 supports more than 155.5 Mbps data rates and uses a 5 V supply according to the supplied distributor specifications. Its four outputs are designed around approximately 350 mV differential signaling. Compared with conventional single-ended CMOS links, the differential architecture can improve noise immunity and permit useful transmission distance when implemented with controlled-impedance interconnects, proper terminations, and compatible receivers.
The CMOS input stage accepts TTL/CMOS logic levels, allowing the driver to sit directly between a digital controller or serializer and a balanced cable connection. Four channels provide useful density where several independent links are required, such as instrumentation, industrial data acquisition, telecommunications equipment, and test systems. The companion line receiver identified on TI's product page is the DS90C032.
For point-to-point LVDS links, route each differential pair on a controlled-impedance PCB trace or use a cable with the required impedance. Provide the receiver-side termination specified by the system design, keep differential traces close together, and minimize stubs and layer transitions. The TTL/CMOS interface and four-channel organization make the part convenient, but signal-integrity layout and an appropriate receiver remain central to reliable operation.
This page combines the verified 155.5 Mbps, four-driver, 5 V, 16-SOIC, and 350 mV characteristics with sourcing guidance and implementation considerations that go beyond a basic distributor listing.

일반적인 애플리케이션
DS90C031TM 적합 용도: 6 애플리케이션s: High-Speed Point-to-Point Data Links, Industrial Instrumentation Interfaces, Test and Measurement Systems, Telecommunications Equipment, Industrial Data Acquisition, Computer and Digital Control Interfaces.
High-Speed Point-to-Point Data Links
The DS90C031TM fits point-to-point links requiring four differential channels at rates above 155.5 Mbps. Place one channel's TTL/CMOS input near a digital transmitter and route its LVDS pair through a controlled-impedance PCB trace or cable to a compatible receiver. The differential output is approximately 350 mV, while the input stage accepts TTL/CMOS levels. The key performance consideration is maintaining matched routing, proper return paths, receiver termination, and controlled skew across all four channels.
추천
Industrial Instrumentation Interfaces
The four-driver arrangement is useful in industrial instrumentation where several low-voltage differential signals must leave a controller or measurement board. DS90C031TM accepts TTL/CMOS logic and operates from a 5 V supply, while its LVDS outputs can carry data above 155.5 Mbps over balanced interconnects. Use controlled-impedance routing, maintain continuous ground references, and select a receiver whose input characteristics match the system termination. The driver reduces susceptibility to common-mode noise compared with a single-ended output.
추천
Test and Measurement Systems
DS90C031TM can provide four high-speed differential drive channels in test equipment where controller outputs must cross a chassis or board interface. Its greater-than-155.5-Mbps capability is suitable for digital test data paths, synchronization signals, and high-speed instrumentation links. Keep each differential pair adjacent, avoid long unterminated stubs, and verify the receiver threshold and termination arrangement on the instrument interface. The 16-pin SOIC package supports compact placement, but exposed routing quality remains more important than package area alone.
추천
Telecommunications Equipment
The DS90C031TM is applicable to telecommunications and serial-interface equipment requiring multiple LVDS transmissions at high data rates. Four independent CMOS differential drivers can reduce the number of discrete line-driver packages in a board design while supporting TTL/CMOS source logic. The design must account for connector loss, cable impedance, receiver termination, and any transmission-line discontinuities. Above 77.7 MHz, small layout differences can affect edge quality, so use the manufacturer application guidance and validate eye, jitter, and common-mode behavior.
추천
Industrial Data Acquisition
DS90C031TM can distribute high-rate control, timing, or acquisition-related signals across balanced links in an industrial data-acquisition system. Its four-channel organization suits systems that need multiple point-to-point differential paths, while the 5 V supply and TTL/CMOS inputs simplify interface with CMOS control logic. Because the driver does not include a receiver, every channel requires a compatible endpoint and defined termination. PCB pair geometry and ground-return continuity should be verified over the full operating temperature range of -55°C to +125°C.
추천
Computer and Digital Control Interfaces
DS90C031TM is suitable for digital control boards that need to translate CMOS logic into low-voltage differential signals for a cable or inter-board link. Four drivers provide parallel channels for control, status, or high-speed data, provided each destination accepts LVDS. The approximately 350 mV differential output helps implement a balanced link, but the receiving device and connector must preserve signal integrity. Keep the driver close to the connector when possible, use a solid reference plane, and avoid crossing split planes beneath active differential routes.

설계 노트
Route each LVDS pair as a tightly coupled differential pair on a continuous reference plane. Keep the pair geometry consistent through connectors and layer transitions, avoid long stubs, and match the controlled impedance required by the board stack-up and receiving endpoint. At data rates above 155.5 Mbps, trace length, pair spacing, and return-path continuity can materially affect edge quality; validate the complete link rather than treating the SOIC footprint as sufficient.
Do not treat DS90C031 as a receiver or transceiver: the verified specifications show four drivers and zero receivers. Use a compatible LVDS receiver at the far end, such as the companion DS90C032 where appropriate, and implement the termination arrangement specified by the complete interface design. Also avoid assuming that a family member with a similar suffix has identical timing, temperature, or electrical limits; compare the exact orderable datasheet before substitution.
Provide a clean 5 V supply and decouple the device according to the manufacturer datasheet. Keep power and ground connections short, use a low-inductance return path, and separate noisy switching nodes from differential routing where possible. Since the verified material identifies a 5 V supply but does not provide current, startup, or power-consumption values, do not infer those figures; obtain them from the complete manufacturer datasheet before sizing the supply.
When replacing a board, compare channel count, package, pin names, supply voltage, input thresholds, output voltage, propagation behavior, temperature range, and termination requirements. DS90C031BTM is described in the supplied comparison as similar but with some differing electrical characteristics, so it is not automatically a drop-in replacement. A valid substitute must preserve the complete pinout and timing/electrical limits, not merely the DS90C031 family name.
규정 준수 정보
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-mineral status. These fields remain unknown rather than being inferred from the manufacturer name or package.
