DS90LV048ATM - 400 Mbps Quad LVDS Receiver | Texas Instruments
Артикул: DS90LV048ATM ✓ АктивенDS90LV048ATM Обзор
An LVDS receiver is an interface integrated circuit that converts a low-voltage differential signal into a complementary CMOS logic output. LVDS, or Low Voltage Differential Signaling, belongs to the differential interface IC hierarchy and supports reliable high-speed communication by comparing the voltage difference between two conductors. By rejecting common-mode noise and using low swing levels, LVDS is well suited to compact industrial, communications, and data-processing systems.
The DS90LV048A family provides four flow-through differential receivers and supports data rates in excess of 400 Mbps. Its 350 mV typical differential input amplitude allows it to operate with the companion DS90LV047A line-driver family. The receiver architecture translates each differential LVDS input into a CMOS output suitable for downstream digital logic, while its quad-channel organization consolidates four links into one 16-pin device.
The flow-through arrangement helps preserve signal timing by keeping the data path direct through the package. This is particularly valuable in point-to-point links where receiver-to-logic propagation delay must remain predictable. A listed 1.5 ns propagation-delay value and 15 mA operating-current figure place the device in the low-power, high-speed interface class, although application-specific limits should be checked against the manufacturer datasheet before final timing and power-budget calculations.
Typical uses include point-to-point links between a transmitter and field-programmable gate array, industrial control equipment, video-processing systems, and other high-speed digital backplanes. The quad receiver can reduce component count when four differential channels are required. It is also appropriate where a 3.3 V supply and CMOS outputs match the receiving logic, while cable length, connector behavior, connector pin assignments, and system-level LVDS timing remain design constraints.
For PCB implementation, place the receiver close to the source connector, route the differential pair as a tightly coupled pair, and provide a solid ground reference. Keep unused receiver inputs properly terminated according to the device recommendations. Confirm supply sequencing, output-load limits, and the relationship between input threshold, propagation delay, and system timing before operating the link at its maximum data rate.
This product overview combines the manufacturer's functional description with package, interface, sourcing, replacement, and layout guidance. It also distinguishes genuine same-footprint receiver options from functionally similar parts that require separate electrical and timing review, helping engineers select a replacement without overlooking enable, pinout, or temperature requirements.

Типичное применение
DS90LV048ATM подходит для 6 применениеs: FPGA Point-to-Point Data Links, Industrial Control and Monitoring Systems, High-Speed Backplane Interconnect, Video and Imaging Data Transfer, Communications and Data-Processing Equipment, Test and Measurement Data Paths.
FPGA Point-to-Point Data Links
The DS90LV048ATM is appropriate when an FPGA or other CMOS logic device must receive several high-speed differential channels. Its four flow-through receivers support rates above 400 Mbps, equivalent to 200 MHz, while a typical 350 mV differential input matches the signal level expected from an LVDS transmitter. Using four channels in one 16-pin SOIC reduces the number of receiver packages, but each pair requires careful routing, a continuous reference plane, and skew control. Verify the transmitter output, FPGA input thresholds, propagation delay, and timing budget before committing to the maximum data rate.

Industrial Control and Monitoring Systems
The DS90LV048ATM can receive low-voltage differential data links in industrial control, monitoring, and remote-I/O equipment. Its four receiver channels support compact point-to-point interfaces, while the listed 3.3 V supply and -40°C to +85°C operating range fit many embedded industrial designs. Differential signaling reduces sensitivity to common-mode interference compared with single-ended interconnects, but successful deployment still depends on cable routing, connector selection, grounding, and electromagnetic compatibility. Validate the complete channel across temperature, cable length, and the worst-case data pattern.
Рекомендуется
High-Speed Backplane Interconnect
The DS90LV048ATM can serve as the receiving endpoint for short, point-to-point channels on a high-speed digital backplane. Its quad flow-through architecture preserves a direct data path, and the listed 1.5 ns propagation delay provides a concrete timing parameter for receiver-to-logic analysis. Four channels per package also help limit connector density compared with discrete single receivers. However, operation above 400 Mbps requires low-loss routing, tightly coupled differential pairs, uninterrupted reference planes, and verified connector and via transitions. Simulate the complete interconnect rather than relying on device specifications alone.
Рекомендуется
Video and Imaging Data Transfer
The DS90LV048ATM is useful in compact video or imaging systems that distribute low-voltage differential data from a transmitter to CMOS processing logic. The four parallel receiver channels can recover multiple related signals, and the device supports data rates above 400 Mbps for high-speed point-to-point links. Differential signaling is particularly helpful in systems containing switching converters or other sources of common-mode noise. The design should still account for connector geometry, cable skew, receiver input tolerance, and the timing relationship between recovered outputs and downstream processing.
Рекомендуется
Communications and Data-Processing Equipment
The DS90LV048ATM fits communication and data-processing modules that use low-power LVDS links between circuit boards or between a controller and a transceiver. Its four channels support a compact receiver implementation, and the 3.3 V operating supply aligns with modern CMOS logic. Because the receiver is designed for low power dissipation, it can suit space- and power-constrained equipment when system clocking and thermal budgets permit. Check propagation-delay tolerance, input sensitivity, output loading, and logic thresholds across every supported voltage and temperature condition.
Рекомендуется
Test and Measurement Data Paths
The DS90LV048ATM can be used in test and measurement equipment that receives high-speed differential commands or status data from an external controller. Its four receiver channels provide a practical way to consolidate several low-voltage links, while operation above 400 Mbps supports demanding data-transfer paths. The 16-pin SOIC package simplifies assembly in moderate-size instruments. For laboratory-grade performance, characterize the cable, connector, and fixture because reflections and impedance discontinuities can influence the received signal even when the receiver itself is operating correctly.

Заметки по проектированию
Route each LVDS pair as a tightly coupled, length-matched differential pair over a continuous reference plane. Keep the DS90LV048ATM close to the connector or transmitter, minimize stubs and test-pad branches, and avoid splitting the pair across PCB layers. Although the receiver accepts a typical 350 mV differential input, edge-rate-dependent attenuation and connector transitions can still degrade signal integrity at the supported high data rate.
Do not assume that every part described as an equivalent LVDS receiver is automatically pin-to-pin interchangeable. Compare the 16-pin SOIC footprint, differential input assignment, enable or fail-safe behavior, CMOS output polarity, input threshold, propagation delay, supply range, and temperature grade. In particular, confirm unused-input handling in the manufacturer datasheet before finalizing the schematic and PCB layout.
Use the listed 1.5 ns propagation delay as one component of the link timing budget rather than as a complete channel-delay figure. Add receiver variation, transmitter skew, logic setup and hold requirements, connector delay, and interconnect delay. Estimate: total data-path margin equals the available period minus all measured or specified delay components; use the minimum period corresponding to the highest supported data rate.
Plan the 3.3 V rail for both static and switching current from the receiver and any adjacent logic. Estimated: receiver dissipation equals supply voltage multiplied by operating current; with 3.3 V and 15 mA, the receiver-only calculation is 49.5 mW before PCB losses or adjacent-device effects. Verify this estimate against worst-case supply current, temperature, and output-loading conditions in the manufacturer electrical-characteristics tables.
