Silicon Laboratories (NASDAQ:SLAB), which has seen much success
in the cellular chip market, has also focused its attention on the VoIP market. The company offers integrated solutions for
voice over ADSL applications, enabling the design of telephones with VoIP capability.
Silicon Labs offers its Si3216 wideband audio ProSLIC, which is
a CMOS subscriber line interface circuit for high voice quality VoIP application. As a testimonial to the value Silicon Labs

such as video telephony and VoIP Internet access equipment. The chip provides an analog telephone interface with the telephone
network.
Later in January 2005 Silicon Laboratories' Si3210 ProSLIC solution
and Si3050 voice direct access arrangement (DAA) was selected by Askey Computer Corporation. Askey, which manufactures cable
