DS90C032TMX - Quad LVDS Receiver, 155.5 Mbps | Texas Instruments
N.º da peça: DS90C032TMX ✓ AtivoDS90C032TMX Visão geral
An LVDS receiver is an interface IC that converts low-voltage differential signaling into complementary CMOS logic levels. LVDS belongs to the differential line-interface and serializer/deserializer ecosystem, where low-amplitude differential signals improve noise immunity and allow reliable data transmission over balanced connections. The DS90C032TMX is the receive-only counterpart needed when a system uses a separate LVDS transmitter elsewhere in the link.
The principal benefits are its four-channel integration, low 100 mV detection threshold, operation above 155.5 Mbps, and 5 V single-supply operation. Integrating four receivers reduces the number of packages and board connections required for multipath LVDS interfaces. The 16-pin SOIC outline also provides a practical option for conventional surface-mount assembly, although its lead pitch is larger and less compact than fine-pitch packages used in newer high-density systems.
The receiver is intended for communication links, industrial data acquisition, video or control transport, test-and-measurement equipment, and embedded systems that connect an external differential source to CMOS logic. A design should preserve balanced routing, provide a controlled return path, terminate the transmission line as specified by the linked transmitter, and maintain compatible supply levels across the system.
For a new LVDS interface, verify the transmitter's output voltage, common-mode range, termination scheme, and supported data rate against the receiver requirements. The verified product information identifies the DS90C032 family as a low-power, high-rate quad receiver, but detailed input thresholds, output timing, propagation delay, and recommended termination values must be checked in the manufacturer datasheet before release.
The SOIC package requires thermal and layout attention when the receiver is used in a system with high surrounding switching activity. Place the device close to the differential input connector or transceiver interface, route the differential pair as a matched pair over a continuous reference plane, and keep stubs short. This page consolidates the verified device identity, package, interface capability, sourcing links, and engineering constraints to support initial component selection and PCB planning.

Aplicações típicas
DS90C032TMX é adequado para 6 aplicaçãos: Industrial LVDS Data Acquisition, Board-to-Board Communication, Test and Measurement Equipment, Video and Control Transport, Embedded System Interconnects, Low-Power Communication Equipment.
Industrial LVDS Data Acquisition
The DS90C032TMX fits industrial data-acquisition equipment that must recover four low-amplitude differential signals from a remote sensor or instrument. Its four integrated receivers reduce the package count when several measurement channels arrive over balanced wiring, while the 100 mV detection threshold supports reliable reception of small LVDS signals. The device accepts a 4.5 V to 5.5 V supply and supports rates in excess of 155.5 Mbps. Route each pair as a controlled impedance connection over a continuous plane, keep stubs short, and apply the termination prescribed by the linked transmitter and manufacturer interface guidance.
Board-to-Board Communication
DS90C032TMX is appropriate for board-to-board links where four differential channels must terminate in CMOS logic on the receiving board. The +1.2 V nominal signal center and ±1 V common-mode window are suited to the LVDS signaling arrangement identified by Texas Instruments, while operation above 155.5 Mbps provides margin for high-speed control or data traffic. Its 16-pin SOIC package simplifies assembly on established surface-mount PCB processes. Maintain spacing from aggressors that share the ground reference, avoid unequal differential routing, and confirm that the transmitting device provides compatible output levels and termination.
Test and Measurement Equipment
The DS90C032TMX can receive up to four low-level differential channels in test and measurement systems, allowing a compact instrument to recover signals from remote fixtures, digitizers, or modular test cards. A 100 mV detection capability is useful when signal amplitude must be preserved over a balanced interconnect, and the quad architecture limits board area compared with four separate receiver packages. The 16-pin SOIC remains easy to inspect and rework during prototype development. Validate the complete channel with the intended transmitter, connector, cable, and termination because a compliant receiver alone does not guarantee end-to-end eye closure.
Video and Control Transport
DS90C032TMX can support multipath LVDS transport in equipment that distributes synchronized control information or low-resolution video-related data. Four receivers in one package provide a practical channel-count balance for compact backplanes and control cards, and the verified capability above 155.5 Mbps exceeds many legacy control-link requirements. Because LVDS is differential, the receiver should be placed near the connector or source and connected to a balanced trace pair with an uninterrupted reference plane. Check output timing, logic levels, and allowed data formats in the full manufacturer document before treating the interface as a substitute for a dedicated video serializer.
Embedded System Interconnects
The DS90C032TMX fits embedded systems that exchange several high-speed differential signals with an external controller, remote head, or expansion module. Its 155.5-Mbps-class interface capability supports compact command and status links, while integration of four channels reduces connector-side component count. The 5 V supply range makes the receiver suitable for systems that already operate around 4.5 V to 5.5 V, provided the associated CMOS logic uses compatible levels. Preserve the LVDS common-mode window, use matched pair routing, and isolate any ground-potential difference through the system-level connection strategy rather than adding arbitrary series components.
Low-Power Communication Equipment
DS90C032TMX is applicable to low-power communication equipment requiring multiple LVDS receive channels without allocating four separate receiver packages. The family is specifically described by Texas Instruments as intended for ultra-low power dissipation and high data rates, making channel consolidation useful where board area and standby behavior matter. Its four-channel SOIC implementation preserves a straightforward 16-pin surface-mount footprint. Ensure the linked transmitter's output amplitude, common-mode offset, and termination match the receiver's 100 mV threshold and ±1 V window. Review supply-current and power-consumption curves from the complete manufacturer data before final thermal and battery-budget calculations.

Notas de projeto
Route every DS90C032TMX differential input as a coupled pair with symmetrical geometry and a continuous reference plane. Keep the receiver close to the connector or transmitter, minimize vias, and avoid unmatched stubs because the verified minimum detectable differential signal is only 100 mV. Confirm the manufacturer's recommended termination arrangement with the specific transmitter rather than adding a generic resistor without accounting for the complete LVDS network.
The receiver's verified input window is ±1 V common-mode around a +1.2 V center. Check source amplitude, offset, channel skew, connector loss, and ground-potential differences before enabling the link. A receiver that detects 100 mV is still sensitive to impedance discontinuities and coupled noise, so use a controlled impedance PCB stack-up and keep unrelated high-current or high-speed traces away from the differential pairs.
Decouple the 5 V supply locally and use the manufacturer-specified input and output capacitor values after reviewing the complete DS90C032 data sheet. Place the supply bypass capacitor adjacent to the device's supply and ground pins, while maintaining a low-impedance return path for high-frequency transients. The supplied data verifies operation from 4.5 V to 5.5 V but does not provide capacitor values or supply-current limits.
Do not treat the DS90C032TMX, DS90C032TM/NOPB, and DS90C032TMX/NOPB orderable strings as automatically interchangeable without checking TI ordering information. The NOPB suffix may affect labeling and compliance documentation, while package suffixes can identify a mechanically related but differently ordered device. For a second-source substitution, compare the exact pin drawing, pin functions, supply limits, input thresholds, and electrical timing against the specific orderable datasheet.
