CMOS image sensor enables functionality for industrial camera design

The X-Class image sensor platform enables a new dimension in camera design by supporting multiple CMOS pixel architectures within the same image sensor frame.

This allows a single camera design not only to support multiple product resolutions, but also different pixel functionality, such as larger pixels that trade resolution at a given optical format for higher imaging sensitivity, designs optimised for low noise operation to increase dynamic range, and more.

By supporting these different pixel architectures through a common high bandwidth, low power interface, camera manufacturers can leverage existing parts inventory and accelerate time to market for new camera designs.

The initial devices in the X-Class family, the XGS 12000 and XGS 8000, are based on the first pixel architecture to be deployed in this platform – an advanced 3.2 µm global shutter CMOS pixel that features superior imaging performance, high image uniformity, and low noise.

The XGS 12000 provides 12 MP (4096 x 3072 pixel) resolution in a one-inch optical format to supply the imaging detail and performance needed for modern machine vision and inspection applications.

The device is planned to be available in two speed grades – one that fully utilises 10GigE interfaces by providing full resolution speeds up to 90 fps, and a lower price version providing 27 fps at full resolution that aligns with the bandwidth available from USB 3.0 computer interfaces.

The XGS 8000 provides 4k / UHD (4096 x 2160 pixels) resolution in a 1/1.1 inch optical format and is also planned to be available in two speed grades (130 and 75 fps), making the device ideal for broadcast applications.

The package dimensions of both devices combine with a low thermal profile enabled by the low-voltage, low-power architecture of the X-Class interface to make them fully compatible with compact 29 x 29 mm2 camera designs.

“As the needs of industrial imaging applications such as machine vision inspection and industrial automation continue to advance, the design and performance of the image sensors targeting this growing market must continue to evolve,” said Herb Erhardt, Vice President and General Manager, Industrial Solutions Division, Image Sensor Group at ON Semiconductor.

“With the X-Class platform and devices based on the new XGS pixel, end users have access to the performance and imaging capabilities they need for these applications, while camera manufacturers have the flexibility they require to develop next-generation camera designs for their customers both today and in the future.”

The XGS 12000 and XGS 8000 will begin sampling in the 2Q2018, with production availability scheduled for the 3Q2018. Both devices will be available in 163-pin LGA packages in monochrome and color configurations.

Additional devices based on the 3.2 µm XGS pixel as well as products based on other pixel architectures are planned for the X-Class family in the future.
