DS90CP02SP - 1.5Gbps 2x2 LVDS Crosspoint Switch | Texas Instruments
MPN: DS90CP02SP ✓ Hoạt độngDS90CP02SP Tóm tắt
A crosspoint switch is a signal-routing IC that directs data from multiple inputs to multiple outputs under control of external logic. In the broader electronics hierarchy, a crosspoint switch belongs to logic ICs and multiplexing or switching circuits. The DS90CP02SP is specialized for differential LVDS links rather than ordinary single-ended digital signals. Its architecture is intended to preserve data integrity across long or electrically demanding interconnect paths, including backplanes and balanced cables.
The principal verified feature is its 1.5-Gbps data rate for a 2x2 LVDS crosspoint configuration. The two-channel architecture supports routing flexibility in systems that need selectable signal paths. The non-blocking operation permits simultaneous routing options without forcing a fixed point-to-point mapping. Fully differential paths help reject common-mode noise and maintain signal polarity through controlled differential signaling. The package is identified by distributors as 28-UQFN, with a 5 mm by 5 mm body.
The device is targeted at high-speed communications and signal-integrity-sensitive routing. Its differential signal paths can be used when a system must connect source and destination circuitry through a controlled crosspoint rather than a fixed trace. The wide input common-mode capability is identified in the manufacturer description as useful for practical LVDS interoperability, although detailed input thresholds, output levels, timing, power ratings, and temperature limits are not included in the supplied verified data.
Typical applications include LVDS backplane routing, balanced-cable signal switching, industrial control links, communications equipment, and test systems where a compact differential routing element is useful. The same 28-UQFN footprint should be used as the mechanical starting point for PCB layout. The exact pin assignments, recommended resistor networks, trace geometry, and power-decoupling requirements must be confirmed from the official Texas Instruments datasheet before implementation.
A key design consideration is that high-speed differential routing depends as much on PCB layout as on the switch itself. Keep each differential pair tightly matched, minimize stubs, maintain continuous reference planes, and control impedance through the backplane or cable transition. Verify the complete channel with the intended source and destination devices because transmitter amplitude, receiver thresholds, connector geometry, and loss characteristics determine the usable system margin.
This product record combines the verified Texas Instruments device description with distributor package and channel information, a structured application view, and engineering guidance focused on LVDS signal integrity. It is intended to support early design decisions while leaving unverified electrical details explicitly marked for confirmation against the official datasheet.

Ứng dụng tiêu biểu
DS90CP02SP phù hợp cho 6 Áp dụngs: FR-4 Backplane LVDS Routing, Balanced-Cable Signal Switching, Industrial Control Signal Routing, Test and Measurement Signal Paths, Communications Equipment Routing, High-Speed Digital Backplane Control.
FR-4 Backplane LVDS Routing
The DS90CP02SP fits a selectable 1.5-Gbps differential routing point in an FR-4 backplane because its 2x2 crosspoint architecture can connect inputs to selectable outputs without requiring a fixed one-to-one path. Its fully differential LVDS signal paths are intended to preserve signal integrity and noise immunity across a lossy printed-circuit-board interconnect. Place the device where trace geometry, reference planes, connector transitions, and receiver thresholds have been validated together. The key design trade-off is that switching flexibility must be balanced against insertion loss and return-loss budget; a part rated for 1.5 Gbps does not remove the need to characterize the complete channel.
Được đề xuất
Balanced-Cable Signal Switching
For balanced-cable links, the DS90CP02SP can provide a controlled differential crosspoint where the cable termination and receiver interface are designed for the intended LVDS levels. Its 1.5-Gbps capability makes it relevant for high-speed communication paths rather than low-rate control signals, while the fully differential implementation helps limit susceptibility to common-mode disturbance. The device should be used only after confirming output voltage, input threshold, supply voltage, and cable-loss specifications from the official datasheet. In a real link, connector launches and cable transitions must be treated as part of the channel rather than assuming that the IC alone guarantees reliable operation.
Được đề xuất
Industrial Control Signal Routing
The DS90CP02SP can serve as a high-speed routing element in industrial equipment that needs to select between differential signal sources without changing the external cable arrangement. Its 2x2 non-blocking format provides a compact way to organize two differential paths, and the 1.5-Gbps target is more than appropriate for many communication links carrying control, status, or synchronized data. Industrial designs should still account for the unknown supply voltage, temperature range, and input thresholds in the supplied data. Validate EMC, grounding, isolation strategy, and fault behavior at system level before deploying the switch in a safety- or production-critical path.
Được đề xuất
Test and Measurement Signal Paths
The DS90CP02SP is suitable for test systems that need to route two high-speed differential channels between instrumentation, fixtures, and device-under-test circuitry. The non-blocking 2x2 arrangement can simplify source selection while the fully differential paths help preserve signal polarity through the test fixture. Because the verified material does not provide timing, jitter, insertion-loss, or return-loss curves, engineers should characterize the complete fixture with the intended transmitter and receiver. Short, controlled traces, proper terminations, and a continuous ground reference are especially important when the device is used near instrument connectors or long cable assemblies.
Được đề xuất
Communications Equipment Routing
In communications equipment, the DS90CP02SP can provide a selectable differential route for a 1.5-Gbps link when the design needs two inputs, two outputs, or a compact matrix routing element. The fully differential LVDS implementation supports noise-immune signal transfer, while the non-blocking architecture can simplify system configuration and routing control. Integration requires careful attention to the exact pinout, control protocol, power rails, and termination arrangement, none of which are fully available in the supplied search snippets. Confirm the manufacturer's recommended layout and test the assembled board across temperature, cable length, and connector or backplane variations.
Được đề xuất
High-Speed Digital Backplane Control
The DS90CP02SP can be used in a high-speed digital backplane that needs controllable differential routing rather than a permanent point-to-point connection. Its 2x2 configuration allows the system designer to select signal paths while preserving the LVDS signaling convention across the board. The most important engineering step is to maintain controlled differential impedance and minimize discontinuities between the switch, connector, and far-end receiver. The verified data supports the 1.5-Gbps positioning and 28-UQFN package, but it does not provide enough detail to calculate a complete channel budget. Use the official datasheet and measured SI data before release to production.

Ghi chú thiết kế
Treat the DS90CP02SP as part of a complete LVDS channel, not as an isolated 1.5-Gbps component. Keep each differential pair tightly matched, minimize stubs and layer transitions, use a continuous reference plane, and verify impedance against the board stack-up. The manufacturer identifies lossy FR-4 backplanes and balanced cables as intended applications, so connector launches and cable transitions must be included in the insertion-loss and return-loss budget.
Use the manufacturer's 28-UQFN land pattern and pin table rather than a generic UQFN footprint. Place the device close enough to the relevant differential connectors or backplane launches to minimize trace exposure, while preserving the required return path. Because the supplied verified data does not expose pin names, power pins, or exposed-pad details, do not finalize the PCB layout until those items are confirmed from the official datasheet.
Do not treat DS90CP02SP, DS90CP02SP/NOPB, and DS90CP02SPX/NOPB as interchangeable solely because distributor listings use similar names. Confirm the exact orderable suffix, package marking, lifecycle status, pinout, temperature grade, and supplier authorization. Also verify LVDS input thresholds, output levels, supply voltage, termination values, and control timing against the manufacturer datasheet before releasing a replacement or second-source BOM.
