The Santa Clara, California-based company now expects revenue in the quarter to September 30 to be in the range of $71m to $73m, down almost 15% on the previous three months, and way below the $86m to $92m it originally predicted.

PMC-Sierra said that generally improved availability of semiconductor components is causing a reduction in orders. Despite the dip in sales, the company said it still expects revenue for the first nine months to be between 23% and 33% up on the same period last year.
