IN Brief:
- APXpress offers selectable 4, 8, 16 and 32 Gbps link rates, with more than 500 independent virtual data channels.
- APIX transmits high-resolution video and control information, including 4K streaming and configurations of up to four displays per lane.
- ISELED and ILaS combine individually controlled lighting, sensors and selected actuators using a shared local network.
Inova Semiconductors will demonstrate APXpress, APIX and ISELED/ILaS connectivity at electronica 2026, linking high-speed robotic data, distributed displays and local lighting controls. The Munich-based chip developer specifies selectable APXpress rates of 4, 8, 16 and 32 Gbps, allowing different electronics architectures to share a high-capacity serial link.
APXpress organises traffic into more than 500 independent virtual data channels, with bandwidth and latency settings assigned to individual channels. A robotic system can consequently carry camera images, sensor information and control traffic over the same link while giving those streams different transport allocations. The quoted gigabit rates describe physical link capacity, not bandwidth available simultaneously to each logical channel. Transport overhead and the combined traffic load affect usable application throughput.
Inova will connect sensors and cameras through an APXpress network in a robot control demonstration. Image streams can produce sustained bursts of data, whereas command messages and feedback often need predictable handling. Setting channel priorities and allocations can help separate their requirements without giving every peripheral dedicated cabling. The response time at an actuator nevertheless includes sensor acquisition, processing and the receiving controller as well as network transfer.
As more devices share a connection, the engineering calculation expands beyond the nominal link rate. Data encoding, payload size, scheduling and possible simultaneous transfers determine whether a proposed traffic mix fits the available capacity. Bursts from several cameras can fill queues at the same instant, so capacity planning must account for peak combinations of traffic as well as average transfer rates. Diagnostic and fault handling must also match the device topology, particularly where a disrupted link could affect several functions. Inova’s individually controlled channel parameters give designers a mechanism for organising these loads; end-to-end timing also depends on the attached sensors, processing hardware and chosen system configuration.
APIX tackles the movement of high-resolution video to remote screens and display controllers. The technology supports 4K video streaming, integrated display control and daisy-chain arrangements of up to four displays per lane. Multiple screens can therefore be arranged around a central processing unit with fewer separately routed connections. Display resolution, refresh requirements and cable length influence the amount of data and signal margin that the physical implementation must support.
A chained display layout also changes the wiring and fault considerations. Each receiver needs suitable power and signal integrity, and the position of a failed connection can determine which downstream screens lose communication. Integrating display control into the video link can simplify the higher-level architecture, although panel interfaces and device-level limits must be checked for the selected APIX parts. The Munich setup will demonstrate those display connections alongside the more general APXpress data network.
A separate car door demonstration connects individually controlled RGB lighting with sensors and selected actuators using ILaS, which extends Inova’s ISELED lighting concept. The LEDs are pre-calibrated and incorporate temperature compensation to manage colour variation, while the shared local cabling carries commands for multiple connected functions. This approach addresses the dense local wiring associated with ambient lighting and control elements rather than the gigabit traffic carried by APXpress.
ILaS uses a segmented daisy-chain architecture with diagnostic and fault protection functions. Segmenting the chain can help identify and contain a connection problem, while temperature compensation addresses a different physical effect — changes in light output as LEDs heat during operation. The local network is relevant to industrial panels as well as vehicle interiors, where several indicators and controls may occupy a confined space.
The Munich demonstrations will run in Hall C5, stand 259, from 10 to 13 November. APXpress covers mixed high-volume data, APIX addresses display transport, and ILaS combines smart lighting with nearby sensing and actuation. Their different physical rates and network layouts give electronics developers distinct options for distributing functions across automotive and robotic assemblies.
