Oct 16 (Reuters) - Chipmaker Xilinx Inc forecast current-quarter revenue largely below Wall Street's estimates as it expects lower revenue at its industrial and aerospace businesses.

Xilinx shares fell 4.5 percent after the company said it expects current-quarter revenue to be up or down 2 percent sequentially.

The forecast implies a third-quarter revenue range of $586.9 million to $610.9 million. Analysts on average were expecting revenue of $607.8 million, according to Thomson Reuters I/B/E/S.

The industrial, aerospace and defense business units accounted for 38 percent of Xilinx's revenue in the second quarter.

"After four consecutive growth quarters in industrial and aerospace and defense, we expect this category to decline sequentially," Chief Financial Officer Jon Olson said on a call with analysts.
