Lattice Semiconductor ( LSCC), the chipmaker, reduced its fourth-quarter revenue outlook because of softer demand in its communications business.

Lattice shares fell 4.9% to $6.27.

The company's previous outlook was for fourth-quarter earnings of 28 cents to 36 cents a share on revenue of $3.26 billion to $3.54 billion in the quarter.

Analysts expect profit of 48 cents a share in the quarter on revenue of $3.41 billion.
