4 to 1 Image Aggregation with CrossLink-NX

Connect Dissimilar Image Sensor Sources with Minimal Latency

Optimized for Video Applications ‐ New video applications in areas of artificial intelligence, machine vision, robotics, drones, virtual reality and automobiles require input from multiple sensors. These sensors can include video cameras, but increasingly non-traditional sensors such as radar, lidar, and sonar are used in these applications as well.

Connect Multiple Image Sensor Data - Lattice CrossLink-NX Family can interface to multiple MIPI CSI-2 compatible sensors and aggregate data to a single CSI-2 output stream, providing an ideal method for combining these dissimilar sensor sources while utilizing MIPI CSI-2 Virtual Channels.

Complete Reference Design - This 4 input to 1 output image aggregation reference design for the CrossLink-NX Family creates a sensor aggregator design where four image sensor data are aggregated and output through HDMI.


  • CSI-2 4 lanes x 4 channel inputs at 371 Mbps/lane inputs
  • Camera sensors are configured by CrossLink-NX using I2C interface
  • RAW10 data are converted to RGB888 on all channels
  • Output image can be changed by the on-board switch
