DS90C241QVSX - 840Mbps 24-Bit LVDS Serializer | Texas Instruments
N.º da peça: DS90C241QVSX ✓ AtivoDS90C241QVSX Visão geral
An FPD-Link II serializer is a high-speed interface IC used within parallel-to-serial display and control links. Its function hierarchy is serializer, high-speed interface IC, interface converter, and semiconductor. By embedding clock information into the transmitted data, the DS90C241QVSX eliminates a separate source-synchronous clock path across a board-to-board or cable connection. LVDS signaling provides a low-power and low-noise transfer environment and allows narrow data paths to replace wider parallel buses.
The principal interface features include 24 parallel inputs, one LVDS serial output, a 5 MHz to 35 MHz operating range, and an 840 Mbps data rate. DC-balanced signaling reduces the magnitude of the differential transition current over long links, which supports cleaner electromagnetic behavior. The serializer is intended for the transmit side of an FPD-Link II chipset, with the DS90C124 or compatible deserializer providing the receiving function.
The DS90C241QVSX supports transparent transfer of 24-bit parallel data and associated control signaling through the serial link. Embedded clock information allows the receiving endpoint to recover the transmission timing. This architecture can reduce connector pin count, cable width, PCB routing width, and the number of layers needed when a wide parallel bus would otherwise need to cross a system boundary.
Typical applications include flat-panel display controllers, industrial panel interfaces, automotive display links, medical imaging equipment, video-processing systems, and other embedded platforms that transfer wide parallel pixel or control data over a compact high-speed serial connection. The device can also serve as the serializer element in a point-to-point serializer-deserializer link.
A primary design consideration is the relationship between pixel-clock frequency, transmitted data rate, transmission distance, connector characteristics, and the receiving deserializer. PCB differential-pair routing should be controlled, and the power and ground connections must support this high-speed interface without introducing excessive return-path discontinuity. Use the pin-description table and timing diagrams in the manufacturer datasheet when assigning tracks and validating signal integrity.

Aplicações típicas
DS90C241QVSX é adequado para 6 aplicaçãos: Flat-Panel Display Interface, Industrial Panel Control Link, Automotive Display and Control, Medical Imaging Equipment, Video Processing Systems, Embedded Control and Data Transfer.
Flat-Panel Display Interface
The DS90C241QVSX fits the transmit side of a wide-panel FPD-Link II connection because it accepts 24 parallel LVCMOS data bits and serializes them at up to 840 Mbps. Its 5 MHz to 35 MHz pixel-clock range accommodates many embedded display timing plans while reducing the number of traces and connector contacts crossing the display boundary. The embedded clock architecture avoids a separate source-synchronous clock conductor, and the DC-balanced LVDS output supports reliable data transfer over a compact board-to-board or cable connection.
Recomendado
Industrial Panel Control Link
The DS90C241QVSX is suitable for industrial panel-control systems that carry pixel data and control information across a narrow high-speed link. A 24-bit parallel interface can be consolidated into one LVDS serial path operating at up to 840 Mbps, reducing connector size and PCB routing demand. The device's 5 MHz to 35 MHz operating range provides a defined clock window for industrial timing, while the related DS90C241IVS ordering variant offers an industrial-temperature-family option when system requirements demand that grade.
Recomendado
Automotive Display and Control
The DS90C241QVSX can support compact automotive display or control links where a 24-bit parallel bus must cross a wiring or connector boundary. Its single LVDS serial output carries data at up to 840 Mbps and includes clock recovery information, allowing the receiver to reconstruct timing without a dedicated clock wire. DC-balanced signaling limits differential transition current and supports cleaner transmission through a constrained harness. Automotive deployment still requires confirmation of the exact ordering code's temperature rating, qualification status, and system reliability requirements.
Recomendado
Medical Imaging Equipment
The DS90C241QVSX is useful in medical imaging and diagnostic-control equipment that must transfer a wide parallel data stream over a compact high-speed connection. The 24-bit parallel input and 840 Mbps LVDS output provide a clear migration path from a wide internal bus to a space-efficient serial link. Embedded clock information simplifies point-to-point clocking between transmitter and receiver, while the DC-balanced output supports low-noise transfer over a controlled board-to-board connection. Medical-system qualification remains a system-level requirement and must not be inferred from the serializer alone.
Recomendado
Video Processing Systems
The DS90C241QVSX fits video-processing boards that receive a 24-bit parallel pixel stream from a local controller and transmit it over a short high-speed link. Serialization at up to 840 Mbps can consolidate the parallel bus into a controlled differential pair, helping reduce board-space use and connector pin count. The 5 MHz to 35 MHz pixel-clock range lets the system designer select an operating point matched to resolution and refresh requirements. Signal-integrity validation should include the cable or PCB channel, connector, receiver thresholds, and clock-recovery performance.
Recomendado
Embedded Control and Data Transfer
The DS90C241QVSX can serialize control, synchronization, and payload data between embedded circuit boards when a point-to-point topology is acceptable. Its 24-bit parallel input allows the transmitting processor or FPGA to present a conventional parallel bus, while the 840 Mbps LVDS link carries the combined stream with embedded clock information. This arrangement reduces the number of long parallel traces crossing a module boundary and supports cleaner routing through a connector. Designers must preserve the documented pin assignments and validate the command protocol independently because the serializer remains transparent to the transported data.

Principais diferenciais
- Direct 24-bit LVDS serialization in one interface IC (vs DS90C241QVSX/NOPB)
- Compact serialized link replaces a wide parallel boundary (vs DS90C241QVS/NOPB)
- Industrial-family ordering option (vs DS90C241QVSX)
Notas de projeto
Route the LVDS serial output as a controlled differential pair with closely matched length and geometry. Keep the pair over a continuous reference plane, minimize vias and stubs, and avoid interfaces that force the pair to cross split planes. The manufacturer datasheet describes DC-balanced signaling and optimized edge rate for reduced EMI; preserving that balance at the PCB and connector transitions helps retain the intended noise and interference performance.
Separate the 24-bit LVCMOS input bus from sensitive analog or clock-sensitive circuitry where practical, and use the shortest practical routing from the source device to the serializer. Maintain the documented clock and data timing relationship at the input. The embedded-clock output reduces the need for a long separate clock trace, but the parallel inputs still require controlled skew because their serialized timing becomes part of the received data stream.
Do not treat a related suffix as automatically interchangeable without checking the ordering table. DS90C241QVSX/NOPB, DS90C241QVS/NOPB, DS90C241IVS, and DS90C241QVSX/E7002353 differ in ordering or qualification details even though their documented interfaces use the same 48-TQFP family. Confirm temperature grade, reel orientation, lead-finish designation, qualification, and lifecycle status before changing the BOM.
Informações de conformidade
The exact ordering code should be checked against the manufacturer product page and datasheet for RoHS, REACH, lead-free, halogen-free, conflict-minerals, and automotive qualification declarations.
