NEW YORK (TheStreet) -- Shares of Silicon Image Inc. are falling by 26.41% to $4.96 on heavy volume in mid-morning trading on Thursday, after the company issued a sales warning for fiscal 2015. The company, which provides connectivity solutions that enable the reliable distribution and presentation of HD content for mobile consumer electronics and personal computer markets, said it's expecting a year-over-year revenue decline of approximately 10%. Silicon said the drop in revenue is due to "a reduction in mobile design wins at one of its largest customers."
