DESCRIPTION

Silicon Laboratories’ broad array of mixed-signal communication devices brings

unsurpassed integration, performance and value to broadband access and voice

telephony solutions. These integrated circuits provide global compliance using a single

hardware solution while reducing the PCB footprint and total solution bill-of-materials.

Optimized for customer premise equipment (CPE) applications, these best-in-class

solutions address global telecom standards through a high degree of programmability.

Additionally, these products are designed using standard digital CMOS. This reduces

power and cost while increasing system performance and flexibility through increased

integration without sacrificing system performance.
