Wolfson Provides Single Front-End Solution to Fast Growing Multi-Function Printer and Scanner Demand
SAN DIEGO & EDINBURGH, Scotland--(BUSINESS WIRE)--Sept. 27, 2004--Wolfson Microelectronics plc today announced a new addition to its portfolio of high-performance analog front-end (AFE) digitizer devices. This new, fast pipeline ADC converter is specifically ADVERTISEMENT
designed for use in high-speed, next-generation digital photocopier products. Digital photocopiers typically use odd/ even two output CCD sensors, either using one for monochrome operation or three for color implementations. Wolfson's latest AFE is designed to be used on a one per sensor basis. It may also find applications in very high-speed, flat-bed scanners.
The new 2-channel Wolfson WM8216 offers a 60 MSPS conversion rate, 10-bit resolution, dual channel operation and correlated double sampling. Power consumption is low at just 330mW typical. It provides a highly integrated solution, integrating all of the major analog signal conditioning and A-D conversion requirements of the interface between image sensor and the main digital architecture of a photocopier system onto a single mixed signal device. This includes a 9-bit programmable gain amplifier and an internal 4-bit DAC, for internal reference level generation, which may be used to reference CIS signals or clamp CCD signals. Alternatively, an external reference may be supplied. Both the analog and digital parts of this device operate from a 3.3V supply.
"Digital photocopiers are sold in a growing and highly-competitive market," said David Milne, CEO of Wolfson. "Good system partitioning between analog and digital parts of the architecture is vital and cost effective high speed data conversion is needed to keep performance up and costs down. The new WM8216 responds to these needs, giving designers the performance they require, within a highly integrated solution that remains straightforward to implement in their system."
Price and Availability
The WM8216 is available in a 32-pin QFN package, priced at $3.73 in quantities of 10,000.
