ams OSRAM CSG8K & CSG14K CMOS Image Sensors
ams OSRAM CSG8K and CSG14K CMOS Image Sensors are high-speed devices in a 20mm x 22mm LGA package for machine vision and video applications. Consisting of 3.2µm pipelined global shutter pixels, the image array allows exposure during read-out while performing true CDS (Correlated Double Sampling) operation. These image sensors feature sixteen sub-LVDS data output channels, each running at up to 1.25Gbit/s, resulting in frame rates of 140fps (CSG14K) or 231fps (CSG8K) in full resolution. Programmable using the SPI interface, the row-windowing or row-subsampling modes allow higher frame rates. A programmable on-chip sequencer generates all internal exposure and read-out timings. External triggering and exposure programming is also possible. The dual exposure HDR (High Dynamic Range) mode can achieve an extended optical dynamic range. The image sensor also integrates black-level clamping.
