DS90C241IVS - 24-Bit FPD-Link II Serializer | Texas Instruments
Référence : DS90C241IVS ✓ ActifDS90C241IVS Présentation
An FPD-Link II serializer is a high-speed interface IC within the LVDS serializer and deserializer category. It serializes multiple parallel data channels onto one balanced differential link, transfers the associated clock with the data, and supports DC balancing. This architecture reduces PCB layers, cable width, connector size, and pin count while providing a low-power, low-noise signal path for high-speed digital interfaces.
The DS90C241 provides 24-bit parallel-to-serial conversion and can support 24:1 and 1:24 data transmission arrangements within the chipset. Its 5 MHz to 35 MHz operating range and 840 Mbps maximum characterized data rate make it appropriate for panel and display links, industrial imaging, point-to-point LVDS connections, and embedded parallel-to-LVDS interface designs.
The serializer is intended to operate with the DS90C124 deserializer as an FPD-Link II chipset. Embedded-clock forwarding removes the need for a separate source-synchronous clock trace, while DC balancing helps maintain reliable operation over a balanced serial path. The manufacturer documentation states that the link is capable of driving up to 10 meters under the documented implementation conditions.
Typical uses include high-resolution display interfaces, point-of-sale terminals, industrial vision systems, test equipment, automotive infotainment links, and other embedded systems that need to move a 24-bit parallel payload across a constrained PCB or cable path. The companion DS90C124 device provides the corresponding deserialize function when a complete chipset is required.
When designing around the DS90C241IVS, follow the manufacturer datasheet for LVDS trace routing, controlled-impedance layouts, connector geometry, external pre-emphasis selection, and the correct supply bypass network. Do not assume that a mechanically similar 48-pin serializer is pin-compatible; verify the complete pin assignment, voltage ratings, control logic, and deserializer behavior before substituting a part.
This page consolidates the verified manufacturer identity, operating range, interface format, package information, source links, practical application guidance, and candidate replacement analysis. Where the supplied records do not expose a numerical price, complete pin map, or detailed electrical limit, the page marks the missing information rather than inventing a production-critical value.

Applications typiques
DS90C241IVS convient pour 6 applications: High-Resolution Display Interfaces, Industrial Machine Vision, Point-of-Sale and Retail Terminals, Embedded Test and Measurement Equipment, Automotive Infotainment Display Links, Industrial Control and Data Acquisition.
High-Resolution Display Interfaces
The DS90C241IVS fits display links that must move a 24-bit parallel payload over a compact LVDS connection. Its 5 MHz to 35 MHz operating range and 840 Mbps maximum data rate support the stated FPD-Link II serializer role, while embedded-clock transmission removes a separate parallel clock route. A board can place the serializer beside the graphics source and connect it to a compatible deserializer over controlled-impedance traces or balanced cable. The practical benefit is fewer routed conductors and less skew exposure than a conventional parallel bus. Because DS90UR and other display serializers may use different pixel mapping or control behavior, the receiver and timing architecture must be validated before substituting a related part.
Recommandé
Industrial Machine Vision
The DS90C241IVS is appropriate for machine-vision and industrial imaging systems that receive parallel pixel data from a sensor or processor and need a lower-noise serial link. The 24-bit input bus can be converted into one LVDS output, reducing the number of high-speed traces that must cross a connector or noisy PCB region. Its documented 5 MHz to 35 MHz range and 840 Mbps rate cover the manufacturer's stated serializer operating class. The embedded clock is useful in factory environments because the source and sink do not depend on a separately routed parallel clock. Implement the link with impedance-controlled routing, suitable LVDS termination, and the documented pre-emphasis resistor, then verify the complete camera-to-processor timing chain.
Recommandé
Point-of-Sale and Retail Terminals
The DS90C241IVS can serialize a 24-bit display or control payload in a point-of-sale terminal where connector space and PCB routing are constrained. One LVDS path replaces a wide group of parallel conductors, while the embedded clock keeps the transmitted payload and timing together in a low-noise differential channel. The device's 5 MHz to 35 MHz range and 840 Mbps maximum rate are appropriate for the manufacturer-described FPD-Link II use class. In a retail design, place the serializer close to the parallel source, route the differential pair as a controlled-impedance pair, and use the specified LVDS termination. Validate display refresh timing and error recovery at the matching deserializer before production release.
Recommandé
Embedded Test and Measurement Equipment
The DS90C241IVS is useful in test and measurement equipment that transfers a 24-bit parallel result or control payload between circuit sections. Serializing the bus limits pin and trace congestion while providing embedded-clock operation and DC-balanced LVDS signaling. With the documented 5 MHz to 35 MHz clock range, the device supports the manufacturer's stated operating class and can move data at rates up to 840 Mbps. A practical implementation places the serializer adjacent to the data source and uses a carefully controlled LVDS route to the receiver. Pre-emphasis can be adjusted through the external resistor, but cable length, connector transitions, receiver thresholds, and shielding determine the useful reach. Bench testing should verify eye quality and data integrity across temperature and power-supply variation.

Automotive Infotainment Display Links
The DS90C241IVS family is relevant to infotainment display architectures that use an embedded-clock LVDS connection between a graphics processor and display electronics. The 24-bit parallel input consolidates multiple video and control lanes into one serial path, while DC balancing and differential signaling help manage signal integrity in longer cable arrangements. The manufacturer describes capability up to 10 meters under documented conditions and user-selectable output pre-emphasis. Automotive deployment must nevertheless verify the exact orderable grade, environmental qualification, temperature range, and interoperability with the selected receiver. The supplied evidence does not establish AEC-Q100 qualification for this specific suffix, so an automotive-grade ordering code must be confirmed before use in a safety-relevant production vehicle.
Recommandé
Industrial Control and Data Acquisition
The DS90C241IVS can carry a 24-bit control or acquisition bus across a cabinet or board-to-board boundary where a broad parallel interface would be impractical. The 5 MHz to 35 MHz operating range and 840 Mbps characterized rate allow the parallel source to be coupled through a low-noise LVDS serial path, while embedded-clock forwarding reduces sensitivity to data-to-clock skew. For a control cabinet, route the differential pair away from switching nodes and provide the manufacturer-specified termination and pre-emphasis. The main design consideration is interoperability: a mechanically matching serializer from the DS90UR family may use different data mapping or chipset behavior. Confirm the complete receiver protocol, reset behavior, clocking, and fault coverage before treating a related part as interchangeable.

Notes de conception
Route the LVDS output as a tightly coupled differential pair on a controlled-impedance PCB layer, with a continuous reference plane and minimal stubs. Keep the serializer close to the parallel source so the 24-bit bus does not become a long uncontrolled high-speed route. Use the manufacturer-defined termination, component spacing, and pre-emphasis resistor selection rather than general-purpose LVDS assumptions. The cited 10 m capability is a documented implementation limit, not a guarantee for every cable, connector, or PCB stack-up.
Separate the LVDS pair from clocks, switching regulators, switching nodes, and other high-energy traces. Match the parallel-input routing to the timing requirements of the 5 MHz to 35 MHz operating range and avoid long stubs between the source device and serializer. Follow the current TI mechanical drawing for the 48-TQFP 7 x 7 mm land pattern and observe all pin and thermal-layout requirements. Because the supplied records do not expose the complete pin map, do not release artwork from package-outline information alone.
Do not treat every 48-pin DS90C241 or DS90UR241 ordering code as automatically interchangeable. Confirm pin names, power rails, control inputs, clock direction, protocol compatibility, and deserializer pairing against the current manufacturer datasheet. Related DS90UR devices may target different display-data mappings, and the QVS ordering variants may differ in qualification or temperature grade. A successful PCB fit alone is not evidence of functional drop-in compatibility.
Use the manufacturer-defined LVDS output pre-emphasis resistor arrangement to control edge rate and channel loss, but adjust it only after evaluating the complete cable and receiver channel. Excessive pre-emphasis can increase edge energy and radiated emissions, while insufficient compensation can reduce eye opening at the far end. Keep the serializer and deserializer supply planes quiet, use the recommended bypassing directly at the device, and validate emissions, eye diagram, and data recovery at worst-case cable length and temperature.
