High Performance Four-Channel AFE with Sensor Timing Generation and LVDS/CMOS Data Output
The CS82L44 is a front-end device for CCD and CIS sensors. The CS82L44 processes and digitizes the analog sensor signals at pixel conversion rates of up to 24 MSPS per channel.
The signal processing for each channel includes reset level clamping (RLC), correlated double sampling (CDS), and programmable polarity, gain and offset adjustment. Voltage references may be generated by an internal DAC or else provided externally.
The output data is available in a variety of digital formats via CMOS or LVDS data interfaces.
The CS82L44 incorporates an RGB LED driver with programmable current sinks and timing control. White LEDs are also supported.
The 3.3 V supply may be provided directly, or else generated using an on-chip LDO. An additional LDO provides a 3.4 V supply for an external sensor.
The CS82L44 is available in a commercial-grade 0.4 mm pitch, 40-pin QFN package for operation from –40° to +85°C.
