DS90C124IV5X - 24-Bit FPD-Link II Deserializer | TI
MPN: DS90C124IV5X ✓ ActiveDS90C124IV5X Overview
An FPD-Link II deserializer is a link receiver within the broader category of interface ICs, serializers and deserializers, and data-conversion devices. It accepts a high-speed differential data stream, detects the embedded clock and data, reconstructs the parallel payload, and exposes it through digital output signals. The DS90C124 specifically performs the deserializer function within the broader DS90C124 serializer-and-deserializer family.
The device's 5 MHz to 35 MHz operating range supports multiple embedded-clock transmission rates, while its 24-bit parallel output width defines the maximum payload represented by one channel. DC-balanced signaling helps maintain a consistent digital signaling level through common-mode voltage variation. The FPD-Link II architecture is intended for point-to-point links carrying video or related high-speed digital data.
At the circuit level, the DS90C124IV5X separates link reception from system data processing. Differential input behavior reduces sensitivity to common-mode noise when the transmit and receive paths are implemented with controlled impedance. Because the device includes clock recovery and data reconstruction functions, the source and sink endpoints must be configured for compatible data rates and link formats.
Typical uses include video backplane links, industrial imaging systems, automotive display interfaces, medical imaging equipment, and other point-to-point systems that need a compact 24-bit deserializer. The device can be paired with a compatible FPD-Link II serializer when the system must transport parallel video data across a cable, PCB backplane, or balanced interconnect.
Designers should confirm the exact pin assignments, supply requirements, differential impedance, decoupling, and pinout in the manufacturer datasheet before routing a board. For LVDS-style links, use controlled-impedance differential pairs, maintain symmetry between the two conductors, and observe the receiver's input and return-path requirements to preserve data integrity.
This page combines the device's confirmed interface characteristics with application guidance, engineering design notes, and availability-focused sourcing information. It is intended to help engineers evaluate the DS90C124IV5X against the physical, protocol, and thermal constraints of a new high-speed interface design.

Typical Applications
DS90C124IV5X is suitable for 6 applications: Industrial Camera Video Link, Medical Imaging Data Transfer, Automotive Display Backplane, Video Backplane Interconnect, Digital Camera Sensor Interface, Test and Measurement Instrumentation.
Industrial Camera Video Link
The DS90C124IV5X fits a point-to-point industrial vision system where parallel image data must cross a cable or balanced PCB link. Its 24-bit parallel output width accommodates a full digital payload, while the 5 MHz to 35 MHz operating range supports a defined range of embedded-clock transfer rates. The deserializer receives a DC-balanced differential stream from a compatible transmitter, reconstructs the clock and data, and presents parallel information to an image processor. Engineers should use the exact timing budget, supply arrangement, and differential routing rules in the Texas Instruments manufacturer datasheet, because receiver tolerance and board loss can determine the reliable cable length.
Recommended
Medical Imaging Data Transfer
The DS90C124IV5X can serve as the receiving element of a high-speed digital imaging path when an image-acquisition subsystem and processing board are separated by a balanced interconnect. The 24-bit data width supports parallel transfer of pixel or imaging payload data, while DC-balanced differential signaling is suited to noise-controlled point-to-point links. The 5 MHz to 35 MHz range allows the system designer to select a link rate appropriate to the source, cable, connector, and processor interface. Before using the device in medical equipment, verify the exact temperature rating, isolation architecture, grounding method, and applicable regulatory requirements for the finished system.
Recommended
Automotive Display Backplane
The DS90C124IV5X is suitable for evaluating a compact digital video connection between an automotive display source and a graphics or display controller. Its 24-bit output width can reduce parallel routing compared with a direct point-to-point implementation, and its 5 MHz to 35 MHz range covers several embedded-clock transfer rates. DC-balanced differential signaling can improve signal integrity when the receiver and transmitter use properly terminated, impedance-controlled paths. For production automotive use, confirm the exact orderable part's temperature range and qualification status, then validate cable, connector, ground-offset, and electromagnetic-compatibility performance at the system level.
Recommended
Video Backplane Interconnect
The DS90C124IV5X is appropriate for a board-to-board video backplane that carries digital payload data over a balanced differential channel. The device's 24-bit parallel output reduces the number of source data signals that must be routed directly into the receiving logic, while its deserializer function handles the high-speed serial link and embedded clock. Within the 5 MHz to 35 MHz operating range, the transfer rate should be selected according to channel loss, connector transitions, clock tolerance, and receiver timing margin. Layout with symmetric differential pairs and uninterrupted reference planes, and consult the Texas Instruments manufacturer datasheet for exact propagation-delay and eye-opening requirements.
Recommended
Digital Camera Sensor Interface
The DS90C124IV5X can be used where a camera or image sensor uses a separate high-speed transmission link to an FPGA or digital controller. Its 24-bit deserializer output provides a parallel interface for pixel processing, while the 5 MHz to 35 MHz operating range allows the link rate to match sensor-output and processor requirements. DC-balanced differential reception is particularly useful across cable or backplane boundaries where common-mode voltage and amplitude may vary. The complete design must include a compatible serializer, suitable line termination, clock and data routing, and power filtering. Use the Texas Instruments manufacturer datasheet to establish receiver timing margin and the exact electrical limits before choosing connector and PCB materials.
Recommended
Test and Measurement Instrumentation
The DS90C124IV5X can provide a compact receive path for laboratory and industrial test systems that move parallel measurement or stimulus data between separate boards. The 24-bit width supports substantial parallel payload, while the 5 MHz to 35 MHz range provides a defined operating interval for selecting an appropriate transfer rate. DC-balanced differential signaling is useful in systems where the transmitting and receiving boards may experience ground-potential differences through cables or fixtures. Keep the receiver on a continuous reference plane, terminate the differential pair as directed by the manufacturer datasheet, and verify timing across temperature and cable tolerances. A compatible transmitter and deterministic clocking arrangement are essential for repeatable measurements.

Design Notes
Route the differential receiver inputs as a tightly coupled, length-matched pair over a continuous reference plane. Avoid stubs, test pads, and unnecessary layer changes that add impedance discontinuities. Keep the receiver path away from switching regulators, clocks, and high-current return paths. The Texas Instruments manufacturer datasheet's layout and input guidelines should be followed because differential tolerance and timing margin depend on the implemented interconnect as well as the device.
Assign separate, short connection paths to every required supply and ground pin, and place the required bypass capacitors directly at their associated device pins. Keep supply and return current paths short to reduce inductive transients and ground bounce. Confirm voltage levels, capacitor values, power sequencing, and exposed-pad connections from the manufacturer datasheet before release; incorrect supply routing can disrupt clock recovery and corrupt received data.
Treat the receive channel as a controlled-impedance differential link from transmitter output through connectors or backplanes to the DS90C124IV5X inputs. Validate worst-case cable length, connector transitions, skew, ground offset, and data rate with an eye or compliance measurement. The manufacturer's switching characteristics identify the acceptable data-eye opening, so installation-specific loss margins should be checked before declaring the link operational.
Compliance Information
Compliance status is not stated in the available product and listing information. Confirm RoHS, REACH, automotive qualification, lead-free, halogen-free, and conflict-minerals status with Texas Instruments for the exact orderable MPN.
