The WM8143-10 integrates the analogue signalconditioning required by CCD sensors with a 10-bit ADC.The WM8143-10 requires minimal external circuitry andprovides a cost-effective sensor to digital domain systemsolution.

Each of the three analogue conditioning channelsincludes reset level clamp, CDS, fine offset level shiftingand programmable gain amplification. The three channelsare multiplexed into the ADC. The output from the ADC isfed to the output bus pins OP[9:0] via a 10/8 bitmultiplexer, enabled by the OEB signal.

The flexible output architecture of the WM8143-10 allows ten-bit data to beaccessed either on a ten-bit bus or via a time-multiplexedeight-bit bus. The WM8143-10 can be configured forpixel-by-pixel or line-by-line multiplexing operation. Resetlevel clamp and/or CDS features can be optionallybypassed. The device configuration is programmed eithervia a simple serial interface or via an eight-bit parallelinterface.

The serial/parallel interfaces of the WM8143-10 arecontrol compatible with those of the WM8144-10 andWM8144-12.
