Silicon Integrated Systems (SiS) disclosed its financial information for September, showing revenue of NT$462 million ($14.4 million). A monthly high for the company during 2009, its September revenue marked a 4.74% increase from the prior month and 4.84% year-over-year. SiS' revenue hit NT$1.34 billion in the third quarter -- a 23.75% sequential growth. The company's first three quarters totaled NT$2.91 billion, which is down 39.34% from last year.

SiS' PC chipset business accounts for some 65% of its revenue, with about 60% company from the notebook market and 5% from desktops. Representing about 30% of the company's revenue is its Xbox chipset business, with shipments spurting some 30% sequentially in the third quarter -- though, that growth is expected to drop off in the fourth quarter.

Recognizing the inevitable impact from Intel's move to one chip solutions -- which SiS expects to be the standard late next year -- the company has turned its focus to touchscreen controllers and USB 3.0 IC development.
