The list of communications chip makers warning of revenue shortfalls this week is complete now.

PMC-Sierra

(PMCS)

said Thursday that revenue for the quarter ending July 1 will fall to a range of $93 million to $95 million.

PMC-Sierra also said that it will lose 7 cents to 9 cents a share. According to

Thomson Financial/First Call

, analysts had been expecting revenue of $102 million and a loss of 2 cents a share.

PMC-Sierra attributed the shortfall to continued weakness during the quarter. So far this week,

Applied Micro Circuits

(AMCC)

,

Vitesse

(VTSS)

and

Xilinx

(XLNX) - Get Report

have said that revenue would be less than expected.

Altera

(ALTR) - Get Report

stuck by its guidance, but said it would take a $115 million charge, mostly for inventory overhang.

Broadcom

(BRCM)

warned in early June.

PMC-Sierra also said that it would take charges for goodwill, deferred stock compensation, and slow moving or impaired inventory in the quarter. The company didn't divulge the amount of the charges.

The telecommunications industry -- and its chip suppliers -- has been weighed on by a slowdown in spending that has all but halted demand and created massive inventories throughout the supply chain.
