DS90CR482VS - 5.38Gbps 48-Bit LVDS Deserializer | TI
Référence : DS90CR482VS ✓ ActifDS90CR482VS Présentation
A deserializer is an interface IC that reconstructs a group of parallel digital signals from serialized differential transmissions. In the LVDS Channel Link hierarchy, the DS90CR482VS belongs to the serializer and deserializer class, within interface ICs and semiconductor signal-conditioning products. Balanced differential signaling improves noise immunity by detecting voltage differences rather than relying on a single conductor referenced to ground.
The headline specifications verified for this device are a 48-bit parallel output bus, eight LVDS input channels, a 5.38 Gbps aggregate data rate, and a 65–112 MHz operating frequency range. Its 100-pin TQFP package provides dedicated connections for data, clocking, control, power, and ground. These characteristics make the device relevant to industrial data acquisition, video transport, embedded control backplanes, and other systems that move wide parallel data across a compact cable.
The DS90CR482 receives eight differential data inputs and returns 48 parallel outputs. The DS90CR481 description in the supplied material states that the companion transmitter samples 48 CMOS/TTL input bits every transmit-clock cycle and serializes them into eight LVDS streams, with a ninth LVDS link carrying the phase-locked transmit clock. The receiving device reverses this arrangement and reconstructs the parallel data bus.
Typical system-level uses include high-speed control links, industrial automation equipment, test systems, video interfaces, and communication equipment. In each case, the principal benefits are reduced connector pin count, lower signal-pickup susceptibility than single-ended transmission, and the ability to move a 48-bit parallel bus across a differential link. Cable length, skew, termination, clocking, and ground-return design remain system-level constraints.
Designers should treat the 5.38 Gbps figure as an aggregate signaling rate rather than 5.38 Gbps on every input. Controlled-impedance routing, correct LVDS termination, compliant connector geometry, and verification of inter-pair skew are essential. Exact supply-voltage tolerances, output timing, output capacitance, and recommended passive-component values must be confirmed in the official Texas Instruments datasheet before schematic release.
This page consolidates verified distributor inventory and pricing, official product-page information, a verified TI ordering designation, and practical selection guidance. It also clearly identifies electrical and mechanical details that were not present in the supplied source data, preventing unsupported assumptions about voltage ratings, timing, compliance, or pin assignments.

Applications typiques
DS90CR482VS convient pour 6 applications: Industrial Automation Data Links, High-Speed Video Transport, Test and Measurement Instrumentation, Embedded Control Backplanes, Communication Equipment, Medical and Diagnostic Data Acquisition.
Industrial Automation Data Links
The DS90CR482VS fits industrial automation links that must transfer a wide parallel control or measurement bus across a compact balanced connection. Its eight LVDS inputs reconstruct 48 CMOS/TTL outputs, while the verified 65–112 MHz operating range supports a 5.38 Gbps aggregate rate. Differential reception can reduce sensitivity to common-mode noise in cabinets containing motors, contactors, and switching equipment. The device is normally paired with a compatible DS90CR481 transmitter. Exact industrial temperature, isolation, and EMC qualification must be confirmed from the official datasheet before deployment.
Recommandé
High-Speed Video Transport
The DS90CR482VS can support parallel-to-serial video transport when the system already uses compatible LVDS clocking and data-lane architecture. Eight differential inputs recover 48 parallel output bits at a verified aggregate rate of 5.38 Gbps, reducing the number of conductors required between circuit boards or across a cable. The 100-pin TQFP provides the required data, clock, power, and ground connectivity. Pixel clock rate, video timing, color depth, jitter tolerance, connector loss, and cable skew must be evaluated against the complete system because those values were not supplied.
Recommandé
Test and Measurement Instrumentation
The DS90CR482VS is appropriate for test and measurement equipment that needs to transfer a 48-bit parallel result or control bus over fewer differential wires. Its verified 65–112 MHz range allows the link to carry a 5.38 Gbps aggregate payload, which can support high-rate acquisition, trigger, configuration, or status traffic. Differential signaling helps preserve data integrity across internal cables and backplanes. Designers should verify output timing, input thresholds, clock jitter, power sequencing, and termination values in the official datasheet before building a new acquisition channel.
Recommandé
Embedded Control Backplanes
The DS90CR482VS can serve as the receiving endpoint in an embedded control backplane that distributes parallel processor, DSP, or FPGA data over LVDS links. The device converts eight differential inputs into 48 parallel outputs, minimizing connector contacts compared with a direct parallel bus while retaining a wide data width. Its verified 5.38 Gbps aggregate throughput provides substantial headroom for control, status, and sampled data traffic. The PCB implementation must include controlled-impedance routing, suitable LVDS terminations, solid return paths, and verification that lane-to-lane skew satisfies the timing budget.
Recommandé
Communication Equipment
The DS90CR482VS is suitable for communication equipment requiring a compact link between parallel logic and external differential circuitry. Eight LVDS inputs and 48 CMOS/TTL outputs support a 65–112 MHz Channel Link operating range and a verified 5.38 Gbps aggregate rate. This architecture can shorten wide parallel traces, reduce connector pin usage, and improve immunity to externally coupled noise relative to single-ended routing. Link budget, cable attenuation, connector performance, reference-clock topology, and electromagnetic-emissions requirements must be analyzed at the board and enclosure level before production.
Recommandé
Medical and Diagnostic Data Acquisition
The DS90CR482VS can be evaluated for medical or diagnostic equipment that transports a 48-bit parallel acquisition or control word over a compact differential link. Its eight LVDS inputs and 5.38 Gbps aggregate data rate offer a wide data path while reducing external connection count, and the balanced signaling is useful in systems containing switching or high-gain analog circuitry. However, the supplied sources do not state medical qualification, isolation, safety rating, or operating-temperature limits. Those requirements must be resolved from official documentation and applicable validation records before clinical use.

Notes de conception
Route the eight differential LVDS input pairs as controlled-impedance, length-matched traces with a continuous reference plane. Keep the serializer output and deserializer input connections short where possible, minimize stubs and test-point discontinuities, and avoid routing the links beneath unrelated high-speed or switching nodes. Differential-pair geometry, trace spacing, and terminations must follow the official datasheet and the cable or PCB impedance target.
Validate inter-lane skew, clock jitter, insertion loss, and receiver eye margin at the intended operating frequency across the full 65–112 MHz range. The 5.38 Gbps figure is an aggregate rate across eight data links and does not by itself establish channel margin. Use the official timing and application information to determine termination, equalization or pre-emphasis requirements, and whether a cable, connector, or PCB-riser model must be included.
Place power-decoupling components directly at the device supply and ground pins, and provide a low-impedance return path for every high-speed differential pair. The 100-pin TQFP package has numerous power and ground connections, so follow the manufacturer's recommended pin assignments and plane connections rather than improvising a split supply or ground arrangement. Confirm voltage levels and decoupling values in the datasheet because they were not included in the supplied source data.
Informations de conformité
The supplied source snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The NOPB ordering designation appears in the verified TI listing, but it is not treated as proof of any specific compliance declaration without the corresponding manufacturer documentation.
