The LS4k is a high-speed CMOS system-on-chip (SoC) line-scan image sensor optimized for applications requiring short exposure times and high accuracy line rates.
The CMOS line sensor array utilizes active CMOS pixels with pinned photodiodes to deliver high image quality whilst maintaining the size, cost, and integration advantages of the CMOS technology.
Windowing or sub-sampling allows achieving a maximum line rate of more than 80,000 lines-per-second (lps) for 500-pixel window.
The line-rate, image sub-sampling, windowing, binning, exposure time, gain, and other image processing features are controlled via the sensor configuration register.
The LS4k incorporates an SPI port to communicate with an external host device and three high-speed LVDS ports for data output.
The reference voltages are generated on-chip from an internal band-gap reference. No external components are required. A power-down mode is available for low current consumption when the device is inactive.
