DS90LV047ATMTCX 概述
An LVDS differential line driver is an interface IC that transmits complementary signals through a balanced pair. Because the two conductors carry equal and opposite signals, the transmitted signal is less susceptible to common-mode noise than a single-ended interface. This makes the DS90LV047A family suitable for links requiring low power consumption, high data rates, and reliable point-to-point signal transfer across a board or cable.
The principal verified features are four differential outputs, a 3 V to 3.6 V supply, a 400 Mbps signaling rate, and low-voltage differential signaling. The flow-through architecture supports signal routing where data enters and exits on corresponding package sides. The manufacturer identifies the device as an alternative to high-power pseudo-ECL devices in high-speed point-to-point interface applications.
The DS90LV047ATMTCX is a line driver rather than a receiver, ADC, DAC, or transceiver. Each of its four channels accepts TTL or CMOS logic and produces an LVDS differential output. The 16-pin TSSOP package is suitable for compact surface-mount layouts, while the quad-channel arrangement reduces the number of interface ICs needed when several independent links are required.
Typical applications include high-speed backplanes, point-to-point industrial links, digital video and control paths, communications equipment, and instrumentation requiring reliable differential transmission. The companion DS90LV048A family provides line receivers, allowing a transmitter and receiver pair to be designed into a complete LVDS link.
For PCB design, place the driver close to the source device, route differential pairs with matched geometry, and keep the pair away from unrelated high-current switching nodes. Confirm LVDS output amplitude, receiver compatibility, termination, and edge-rate requirements using the manufacturer datasheet before releasing a new layout.

典型应用
DS90LV047ATMTCX 适用于 6 应用s: High-Speed Point-to-Point Backplane Links, Digital Video and Control Interfaces, Industrial Communication Equipment, Communications and Instrumentation, Clock and Data Distribution, Compact Surface-Mount Control Boards.
High-Speed Point-to-Point Backplane Links
The DS90LV047ATMTCX fits board-to-board and backplane links that need four differential outputs, a 3 V to 3.6 V supply, and a signaling rate up to 400 Mbps. Place the driver near the transmitting logic and route each LVDS pair as a coupled differential trace to a compatible receiver. The main performance consideration is signal integrity: maintain matched geometry, controlled impedance, and a continuous return path so the stated data rate is not undermined by reflections or crosstalk.
推荐
Digital Video and Control Interfaces
The four-channel DS90LV047A driver can carry independent high-speed control or video-related differential signals where LVDS is preferred over a single-ended interface. Its 400 Mbps class supports demanding digital links while the 16-pin TSSOP package keeps the component compact. Validate the receiver’s supported resolution or data rate, and check connector and cable losses before assuming that the driver’s maximum rate is available in the complete channel.
推荐
Industrial Communication Equipment
The DS90LV047ATMTCX is suitable for industrial equipment requiring low-power differential signaling across internal modules or short external links. Its verified -40 C to +85 C operating range and 3 V to 3.6 V supply are useful constraints for equipment operating near a 3.3 V rail. The design must still address grounding, isolation requirements, EMC margins, connector behavior, and the receiver’s fault tolerance rather than relying only on the driver datasheet.
推荐
Communications and Instrumentation
The DS90LV047A family is described by Texas Instruments as an alternative to high-power pseudo-ECL devices for high-speed point-to-point interfaces. This makes the DS90LV047ATMTCX relevant to communications and test equipment where differential transfer is useful but power-efficient CMOS implementation is desired. Confirm input thresholds, output amplitude, timing, and termination against the actual receiver and system clocking requirements.
推荐
Clock and Data Distribution
The quad-driver arrangement allows several differential clock or data outputs to be distributed from one interface IC, reducing the number of separate driver packages in a multi-channel system. The 400 Mbps signaling capability and flow-through architecture are useful for short high-speed paths. Because LVDS is a point-to-point technology, each channel must terminate into a suitable receiver and should not be treated like a multi-drop clock bus.
推荐
Compact Surface-Mount Control Boards
The 16-pin TSSOP package makes the DS90LV047ATMTCX suitable for compact control boards that need four LVDS transmit channels without moving to a larger package. Its 4.40 mm package width and surface-mount construction support standard PCB assembly, although pin-pitch and thermal details must be checked against the manufacturer package drawing. Use a controlled differential-pair layout and confirm local power-supply decoupling requirements before production release.

设计说明
Route every LVDS output as a tightly coupled differential pair with continuous, consistent geometry. Keep the pair away from switching nodes and unrelated high-speed clocks, and provide a continuous reference-plane path beneath the pair. The verified 400 Mbps capability is an interface specification, not a guarantee that every PCB or cable will operate at that rate; receiver thresholds, cable loss, termination, and reflections must be validated together.
Place the DS90LV047ATMTCX close to the transmitting logic and the first receiver or connector so the high-speed differential section remains short. Follow the official package drawing for the 16-pin TSSOP footprint and verify pin numbering before assembly. Do not substitute a generic TSSOP footprint without checking exposed-pad, pin-1, and lead-pitch details against the Texas Instruments package drawing.
Operate the device from a supply within the verified 3 V to 3.6 V range and check the exact input thresholds of the transmitting CMOS logic against the DS90LV047A electrical limits. Confirm that the upstream regulator can support all four active channels and that the receiver and termination network do not impose an unexpected loading. The supplied data does not provide a complete current-consumption table, so those values must be taken from the manufacturer datasheet.
合规信息
The verified cross-reference data specifically states that the NOPB version is RoHS compliant. Reach, halogen-free, and conflict-minerals status were not provided for the exact target MPN.
