Hi Eurah The LM9833 could work with that sensor. Key parameters to consider are the necessary sample rate (4 MHz) and the ability to capture CIS waveforms with pixel counts up to 10296. The LM9833 can sample a single input at up to 6 MSPS and can support line lengths up to 16383. However the LM9833 is a highly integrated device intended to provide a complete scanning solution from sensor to USB1.1 interface. This level of integration makes the device challenging to design around and the USB1.1 interface will limit data throughput. A better choice would be the LM98714 . This also has the needed capabilities to support that sensor, and when interface to an FPGA or other data processing device can give much better data throughput. Please take a look at the LM98714 datasheet and see if it will meet your needs. Best regards, Jim B
