WM8143-10
10-bit/6MSPS CCD Signal Processor
Production Data June 1998 Rev 3f
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.

Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously
operating at or beyond these limits. Device functional operating limits and guaranteed performance specifications are
given under Electrical Characteristics at the test conditions specified
ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically
susceptible to damage from excessive static voltages. Proper ESD precautions must be taken during
handling and storage of this device.
As per JEDEC specifications A112-A and A113-A, this product requires specific storage conditions
prior to surface mount assembly. It has been classified as having a Moisture Sensitivity Level of 2
and as such will be supplied in vacuum-sealed moisture barrier bags.
