WM8143-12 - 12-bit/4MSPS CCD Signal Processor

General Description

The WM8143-12 integrates the analogue signal conditioning required by CCD sensors with a 12-bit ADC.

The WM8143-12 requires minimal external circuitry and provides a cost-effective sensor to digital domain system solution.

Key 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 WM8143-12 are control compatible with those of the WM8144-10 and WM8144-12. Features.
  • Reset level clamp.
  • Correlated double sampling (CDS).
  • Fine offset level shifting.
  • Programmable gain amplification.
  • 12-bit ADC with maximum 4 MSPS.
  • Simple clocking scheme.

WM8143-12 12-bit/4MSPS CCD Signal Processor Production Data Nov. 1999 Rev 4 Description The WM8143-12 integrates the analogue signal conditioning required by CCD sensors with a 12-bit ADC. The WM8143-12 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[11:0] via a 12/8 bit multiplexer, enabled by the OEB signal. The flexible output architecture allows twelve-bit data to be accessed either on a twelve-bit bus or via a timemultiplexed eight-bit bus.
