Front end aims for multifunction market
The WM8214 is a novel high-speed, high-performance analogue front-end circuit for use in flatbed scanners and multifunction printers.
The WM8214 is a novel high-speed, high-performance analogue front-end (AFE) circuit for use in flatbed scanners and multifunction printers (MFPs) In both applications the WM8214 provides a single effective solution without the expense of incorporating analogue circuits in a complex, proprietary processor design

High-performance audio DAC drives novel CD player
Wolfson's high-performance stereo digital-analogue conversion technology is at the heart of two new CD players introduced by hi-fi specialist Rega Research.
Stereo DAC supports Direct Stream Digital
Wolfson Microelectronics has unveiled its first stereo DAC with support for the Direct Stream Digital (DSD) audio data format.
The highly integrated WM8214 features a 40Msample/s conversion rate, a new flexible clocking scheme, and backwards compatibility with current Wolfson WM819x products.
IDC's forecast for the worldwide MFP market shows growth from 14.74 million units in 2002 to 33.27 million units by 2007, a compound annual growth rate of 18% over the period.
Wolfson considers the need for higher scanning page rates will help fuel this growth.
Increasing the scan speed requires higher speed performance in the analogue front end.
Wolfson reckons that the WM8214 will meet the performance needs of new MFP products for the foreseeable future.
"Using a discrete AFE allows designers flexibility in design, lower cost and faster time to market", said David Milne, CEO of Wolfson.
"The WM8214 offers a simple, flexible, cost-effective yet high performance solution to one of the fastest growing consumer markets".
The WM8214 incorporates a 16bit ADC, flexible clamp control with programmable clamp voltage, one-, two- or three-channel operation, with a serial control interface.
The device operates at low power (390mW typical) on a single 3.3V supply, with input video signals from 0.25 to 2.5V (maximum).
The WM8214 is available in a 28-pin SSOP, pin compatible with the existing WM8199.
