Description
The WM8143-10 integrates the analogue signal conditioning required by CCD sensors with a 10-bit ADC. The WM8143-10 requires minimal external circuitry and provides a cost-effective sensor to digital domain system solution. Each of the three analogue conditioning channels includes reset level clamp, CDS, fine offset level shifting and programmable gain amplification. The three channels are multiplexed into the ADC. The output from the ADC is fed to the output bus pins OP[9:0] via a 10/8 bit multiplexer, enabled by the OEB signal. The flexible output architecture allows ten-bit data to be accessed either on a ten-bit bus or via a time-multiplexed eight-bit bus. The WM8143-10 can be configured for pixel-by-pixel or line-by-line multiplexing operation. Reset level clamp and/or CDS features can be optionally bypassed. The device configuration is programmed either via a simple serial interface or via an eight-bit parallel interface. The serial/parallel interfaces of the WM8143-10 are control compatible with those of the WM8144-10 and WM8144-12.
