DS90C031BTM - 155.5 Mbps Quad LVDS Driver | Texas Instruments
部品番号: DS90C031BTM ✓ 生産中DS90C031BTM 概要
An LVDS line driver is a high-speed interface IC that converts single-ended CMOS or TTL logic into a balanced differential signal. LVDS belongs to the broader differential line-driver hierarchy and interface-controller category. Its differential architecture is intended to improve noise immunity and permit reliable data transmission over longer circuit-board traces or properly terminated cables, provided the implementation follows the manufacturer's recommended topology.
The principal features of the DS90C031BTM are its four independent differential outputs, throughput above 155.5 Mbps, and 350 mV differential output signaling. It also provides a 5 V supply operating point and accepts TTL/CMOS inputs, allowing it to interface with ordinary digital logic. Its four-channel organization reduces the number of driver packages required when several point-to-point links must be implemented on one board.
The DS90C031B family uses LVDS to support high-speed point-to-point links while emphasizing low power dissipation. Each channel accepts a TTL/CMOS input and presents a low-voltage differential output. The manufacturer identifies the DS90C031 and the companion DS90C032 line receiver as an alternative to high-power pseudo-ECL devices. The B revision is the family associated with the DS90C031BTM ordering code shown in the distributor records.
Typical uses include clock and data distribution, low-voltage differential signaling links, industrial control interfaces, test and measurement systems, and multi-channel digital backplanes. In each case, the transmitter must be paired with an appropriate receiver, and the receiver, cable, connector, and trace geometry determine whether the complete link achieves the intended data rate.
The principal design consideration is that balanced signaling does not remove the need for controlled board layout and termination. Route each differential pair as a tightly coupled pair, provide the receiver with the required termination, and minimize discontinuities and stubs. Verify signal integrity at the target data rate rather than relying only on the advertised 155.5 Mbps capability.
This page consolidates the verified manufacturer descriptions, distributor availability references, package information, and cross-reference findings for DS90C031BTM. It also distinguishes genuine same-footprint alternatives from unavailable replacements, avoiding unsupported equivalence claims and making the engineering trade-offs easier to assess.

High-Speed Clock Distribution
The DS90C031BTM is appropriate for distributing a high-frequency clock across a board when the destination devices use LVDS inputs. Its four differential transmitters support operation above 77.7 MHz, while the 350 mV differential output provides a low-voltage signal suitable for balanced routing. Each channel accepts TTL/CMOS, allowing ordinary digital sources to drive the transmitter inputs. The device does not regenerate or retime the clock, so rise time, jitter, channel skew, and source-device limitations remain part of the complete clocking budget. Differential traces should remain closely coupled, and the receiving device must provide the appropriate termination. The manufacturer-described DS90C031B family is therefore best viewed as a multi-channel clock transmitter, not as a complete clock-tree solution.

Point-to-Point Data Links
The DS90C031BTM fits board-to-board or backplane point-to-point links that require a low-power differential transmitter. It converts four TTL/CMOS channels into four 350 mV LVDS outputs and supports rates above 155.5 Mbps. This allows several related links to share one interface package while maintaining a common electrical signaling scheme. The transmitter alone does not guarantee link performance: connector loss, cable length, receiver thresholds, termination, and trace impedance determine the usable bandwidth. For reliable deployment, characterize the complete channel with the intended receiver rather than evaluating the driver in isolation. DS90C032 and DS90C032B are the natural companion receivers identified in the verified manufacturer material.
おすすめ
Industrial Control Data Interconnect
DS90C031BTM can be used in industrial control equipment when a controller must transfer several related signals to a remote data-acquisition or motion-control section. The four-channel arrangement reduces the package count compared with discrete single-channel drivers, while LVDS provides a balanced signal better suited to electrically coupled board-level links than ordinary single-ended routing. Its 155.5 Mbps capability gives designers substantial margin for command, status, or synchronized data streams. Industrial implementation still requires attention to ground continuity, cable or connector behavior, and electromagnetic compatibility. The verified data does not provide an industrial temperature grade, isolation rating, or reinforced-creepage specification, so those requirements must be confirmed from the full manufacturer documentation before deployment.
おすすめ
Test and Measurement Instrumentation
The DS90C031BTM is suitable for high-speed data transfer between instrument logic, daughterboards, and external test fixtures that use LVDS. Four outputs allow a measurement system to send clocks, triggers, or coordinated digital commands over balanced connections. Operation above 77.7 MHz and data rates above 155.5 Mbps supports contemporary automated test architectures, provided the receiver and interconnect are designed for the selected rate. Signal-integrity verification is essential because fast edge rates can reveal reflections, impedance discontinuities, connector transitions, and skew that are invisible at lower frequencies. The transmitter is especially useful when reducing the number of driver packages on a crowded instrument mainboard. Its companion role is fulfilled by DS90C032 or DS90C032B receiver devices.
おすすめ
LVDS Backplane Communication
The DS90C031BTM can drive several LVDS channels from one backplane controller, making it relevant to multi-board systems that require balanced, high-speed signaling. Its four differential outputs support more than 155.5 Mbps and translate standard TTL/CMOS logic into 350 mV LVDS pairs. In a backplane, the major engineering constraints are trace impedance, pair-to-pair skew, connector loss, and the receiver's common-mode range. The component does not contain transmit pre-emphasis or receive equalization, so long or lossy channels may require system-level mitigation. Keep each differential pair continuous and tightly coupled, avoid layer transitions and stubs, and use receiver termination recommended by the companion DS90C032 family. Validate the complete channel at production corner conditions.
おすすめ
Synchronized Digital Subsystems
The DS90C031BTM can support synchronized communication between two digital subsystems when several data or control paths must cross a noisy internal boundary. Driving four channels from a single package simplifies channel organization and helps maintain a common interface technology. The 155.5 Mbps data-rate capability and 77.7 MHz clock-rate support provide suitable headroom for transferred data, but they do not guarantee inter-channel skew limits or receiver equalization. Designers should evaluate source timing, output enable behavior, trace length matching, and the receiving device's tolerance to the full LVDS waveform. The transmitter's 5 V operating point and TTL/CMOS input compatibility simplify connection to conventional digital logic. DS90C032 and DS90C032B provide the corresponding receiver functions for a complete four-channel link.

設計ノート
Route each LVDS output as a tightly coupled differential pair with continuous reference to a solid ground plane. Avoid stubs, test pads, excessive vias, and changes in layer or reference-plane geometry beneath the pair. Match the differential impedance specified by the board and complete channel design, and keep unrelated switching or return-current paths away from the pair to reduce differential and common-mode noise pickup.
Treat the DS90C031BTM as one element of a complete signal path rather than as a standalone 155.5 Mbps interface. Verify source edge rate, receiver thresholds, trace loss, connector behavior, cable length, and termination with the intended DS90C032-class receiver. A supported data rate does not guarantee adequate eye opening on an arbitrary PCB or cable assembly, particularly when the complete link includes connectors and unequal routing.
Provide a stable 5 V supply and decouple the device close to its power pins according to the manufacturer datasheet. Keep supply and return paths short, use a low-impedance ground reference, and avoid sharing narrow supply connections with unrelated switching loads. The verified data establishes a 5 V operating point but does not supply the required capacitance values or current limits, so those values must be taken directly from the datasheet rather than guessed.
Do not treat the DS90C031BTM as a transceiver or receiver. It contains four transmitters and no receivers, so each link requires a separate receiving device such as the manufacturer-described DS90C032 family. Also do not infer that a similarly named LVDS part is a drop-in replacement: channel count, pin names, supply requirements, enable logic, and output timing must be compared against the manufacturer pinout before substitution.
コンプライアンス情報
The supplied verified records identify the device, family, package, signaling technology, and basic electrical functions but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields therefore remain unknown rather than being inferred from the manufacturer name or ordering code.
