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.
SYSTEM BENEFITS
• Small footprints save board space and discrete component cost
• Requires only 3.3 V and 5 V power supplies and eliminates the need for costly
additional power supplies
• Reduces system power consumption
• Line voltage/current monitoring for remote system provisioning and fault detection
• Globally compliant solutions enable a single design for all countries
• PCM/SPI or GCI digital interfaces for FXS and FXO ports
APPLICATIONS
• ADSL/cable modems
• Integrated access devices (IADs)
• PBX systems
• Voice over IP (VoIP) gateways and routers
