Eyenix ISP has a 4-lane MIPI-CSI2 RX interface for connecting image sensors and a 4-lane MIPI CSI-2 TX interface for connecting to EZ-USB™ CX3.

Infineon EZ-USB™ CX3 enables USB 3.0 connectivity to EN801/EN805 using a MIPI-CSI2 interface with data speed up to 1 Gbps per lane.

Key features of the kit:

• Bandwidth: 4x CSI-2 lanes, 1 Gbps per lane
• Color formats supported: YUV422 8-bit
• USB camera protocol: UVC
• Supported resolutions:
  
  • 720p @30/50fps
  • 1080p @25/30fps
  • 1080p @50/60fps
  • 1440p @25/30fps (supported by EN805 + IMX335)

Eyenix EN801/EN805 ISP has the following features:

• RGB interpolation
• WDR
• Digital noise reduction
• Adaptive contrast enhance (ACE)
• Histogram equalizer for defog
• Lens shading compensation
• Down and up scaler
