DS90C032TM - 4-Channel LVDS Receiver | Texas Instruments
Référence : DS90C032TM ✓ ActifDS90C032TM Présentation
An LVDS differential line receiver belongs to the line-driver and line-receiver hierarchy within interface ICs. LVDS transmits information as the voltage difference between two conductors, providing a differential signal that can reject common-mode noise and support reliable high-speed data transfer. This DS90C032 implementation converts four differential inputs into individual CMOS outputs, allowing an LVDS link to interface with conventional digital logic.
The DS90C032TM supports data rates above 155.5 Mbps and accepts low-voltage differential signals of 350 mV. Its CMOS outputs are compatible with TTL logic levels, while the device provides a TRI-STATE output function that can be used to multiplex outputs. The quad-channel architecture integrates four receivers into one package, reducing board area for systems that carry several differential signals.
The manufacturer describes the DS90C032 as a CMOS differential line receiver designed specifically around ultra-low power dissipation and high data rates. These characteristics make it relevant to point-to-point LVDS links where data throughput and power efficiency matter more than the multi-driver capabilities of a transceiver. The differential input architecture also helps preserve signal integrity when the transmitted data crosses a cable or PCB interconnect.
Typical uses include high-speed serial links, industrial data acquisition, telecommunications equipment, test systems, and digital backplanes. The receiver can interface an LVDS source to CMOS-based controllers, processors, FPGAs, or counters. The available TRI-STATE function provides additional flexibility when several receiver outputs share a common bus or must be disabled during a system operating mode.
When laying out the receiver, route the differential pair as a tightly coupled pair with a continuous reference plane and minimize stubs. Decoupling capacitors should be placed close to the device supply pins, while the differential traces should avoid discontinuities that could disturb impedance. The provided source data does not specify the complete pin map, termination requirements, operating-temperature range, or supply-current limits, so those values must be confirmed against the manufacturer datasheet before release.
This product summary consolidates the verified manufacturer description, distributor package information, data-rate capability, and drop-in comparison candidates into an engineering-focused reference. It also distinguishes documented attributes from parameters that still require datasheet confirmation, helping designers avoid treating an unavailable or incomplete value as a guaranteed specification.

Applications typiques
DS90C032TM convient pour 6 applications: High-Speed LVDS Data Links, Industrial Data Acquisition, Telecommunications Equipment, FPGA and Processor Interfacing, Test and Measurement Systems, Digital Backplane Interconnect.
High-Speed LVDS Data Links
The DS90C032TM fits point-to-point LVDS links because its four receivers accept 350 mV differential signals and translate them into CMOS, TTL-compatible levels. According to the Texas Instruments manufacturer datasheet, operation above 155.5 Mbps, equivalent to 77.7 MHz, is supported. The device can terminate four high-speed channels near a controller, FPGA, or data-acquisition engine while providing a lower-power interface than a multi-channel transceiver arrangement. The main engineering consideration is preserving controlled-impedance routing from the transmitter to the receiver, including matched differential lengths and minimal stubs. TRI-STATE outputs add flexibility when a system needs to disable or multiplex receiver channels.
Recommandé
Industrial Data Acquisition
The DS90C032TM is suitable for industrial acquisition equipment that receives several low-voltage differential signals from remote sensors or instrumentation. Its four-channel architecture consolidates LVDS-to-CMOS conversion into one 16-pin SOIC, while the verified 155.5 Mbps-plus data-rate capability provides margin for high-throughput serialized measurements. The receiver's CMOS outputs can connect to counters, processors, or FPGA input sections, subject to the timing limits in the manufacturer datasheet. Designers should evaluate common-mode range, input termination, clocking scheme, and isolation requirements at the system level because those values were not present in the supplied verified data.
Recommandé
Telecommunications Equipment
The DS90C032TM can be used in telecommunications equipment that receives low-amplitude differential data across cables, backplanes, or board-level links. Its differential input arrangement and support for data rates above 155.5 Mbps align with high-speed serial backplane links, while the CMOS outputs provide a bridge to control logic. The 350 mV input signal described by Texas Instruments supports direct LVDS integration, reducing the need for separate receive amplifiers in qualified designs. Production deployment still requires checking the receiver against the link's voltage, impedance, jitter, loss, and connector requirements. A controlled-impedance PCB layout and verified power distribution are essential for preserving receiver performance.
Recommandé
FPGA and Processor Interfacing
The DS90C032TM is appropriate when an FPGA, microcontroller, or digital processor needs to consume four LVDS signals. Its four CMOS differential line receivers convert the incoming 350 mV pairs into individual CMOS levels, avoiding four separate discrete receiver packages. The documented rate above 155.5 Mbps can support high-throughput communication, although the actual usable payload depends on encoding, clock recovery, and the FPGA I/O standard. Review pinout, enable timing, output rise and fall times, and supply tolerances before finalizing an interface. If the receiving logic already supports LVDS, a direct FPGA LVDS input may offer fewer components; the discrete receiver is useful when levels, routing, or isolation require conversion.
Recommandé
Test and Measurement Systems
The DS90C032TM can serve as the receive stage in test and measurement equipment that accepts differential data from remote fixtures, instrument buses, or synchronized test nodes. Four receivers in one 16-pin SOIC support dense channel counts, while the 5 V CMOS interface and TRI-STATE capability provide practical integration options. The manufacturer's documented 155.5 Mbps-plus rate is suitable for transferring measurement and control data when the source, clocking, and cable loss are compatible. Laboratory layouts should keep the receiver close to the connector when cable loss or reflections are significant. Calibration, threshold margin, and common-mode behavior must be validated against the complete test architecture because the supplied source does not provide those numerical limits.
Recommandé
Digital Backplane Interconnect
The DS90C032TM can be evaluated for digital backplane links that distribute high-speed differential data between circuit cards. Its support for rates above 155.5 Mbps and 350 mV differential inputs suits point-to-point LVDS channels, while four receivers permit multiple card-to-card lanes to terminate in one package. The key backplane concerns are differential impedance, insertion loss, connector transitions, skew, and reflections rather than raw receiver speed alone. TRI-STATE outputs may help when a card supports bus sharing or controlled output enable behavior. Use the manufacturer's electrical-characteristics tables to establish receiver margins, and perform channel simulation or measurements before production because the supplied verified data does not quantify common-mode range or propagation delay.

Notes de conception
Route each LVDS differential pair as a coupled, controlled-impedance pair on a continuous reference plane. Match the pair length to the source's requirements, avoid test pads and other stubs on the high-speed path, and keep the receiver away from unrelated switching nodes. The supplied data confirms 155.5 Mbps-plus operation and a 350 mV differential input, but it does not specify the required trace impedance or whether onboard termination is included.
Place the DS90C032TM close to the cable or board-to-board connector so that connector loss and reflection are not compounded by long PCB traces. Maintain symmetry between the differential inputs and provide a continuous ground reference beneath the pair. If the transmitter or receiver uses a separate termination network, place that network close to the appropriate device and verify its value against the manufacturer's application information.
Provide a clean 5 V supply and place local decoupling close to the device power pins. Keep switching-regulator routing and high-current paths away from the differential input and CMOS output paths, especially when the receiver is used near a 155.5 Mbps or faster link. The verified sources confirm a 5 V supply but do not provide supply-current limits or recommended capacitance values, so those details must be taken from the official manufacturer datasheet.
Do not assume that every quad differential receiver with a 16-pin SOIC is automatically interchangeable. Verify signal names, enable polarity, fail-safe behavior, input threshold, propagation delay, output timing, power-supply tolerance, and package dimensions before replacing DS90C032TM. The candidate list is limited to devices identified in the supplied cross-reference data, and several manufacturer-specific differences are marked as unavailable rather than inferred.
Informations de conformité
The supplied verified results do not explicitly state the target part's RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from general manufacturer policies.
