Home Products DSL CO Pharos™
Pharos™ Family

Similar to the Maximus™ family, the Pharos™ family of chipsets offer high-performance, high integration, and is the longest reach ADSL PHY solutions for low-power, high-density, ATU-C line cards. The family consists of Pharos and Pharos III chipsets, both offering a full ADSL2/2+/2++ feature set for the next generation of high bandwidth services. In addition, Pharos III offers increased impulse noise protection (INP) and greater interleaver depth for the deployment of robust video and IPTV applications. Pharos differs from Maximus in that the line drivers are integrated with high density line cards. With its extensive feature set, Pharos is well suited for mini-DSLAM, RT, chassis-based DSLAM, and DLC equipment. With innovative eXtremeDSLMAX technology and multiple interfaces, Pharos offers the best in class solution for line cards enabling triple-play voice, video and data services.

The Pharos chipset consists of a monolithic single 12-port digital processor and two-port AFE with integrated line drivers that provide low-chip count, low-power, high-density implementations.
The digital processor offers performance and programmability for efficient and flexible line card solutions. The AFE device with on-chip line drivers is a highly integrated device that significantly reduces required external discrete components, thereby reducing overall Bill of Material (BOM) costs. The device features high-resolution analog-to-digital and digital-to-analog converter circuits, which provide the performance required for high bandwidth applications.
