| 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.
