SE
:

The Amazon
-
SE offers cost
-
effective ADSL2/2+ Modem/Router solutions.

Amazon
-
SE (PSB
50601) comes with a variety of hardware interfaces and it is assembled in a LQFP package

which enables a system board to be built on a

2

layer only PCB. Together with complete
software packages, the

Amazon
-
SE system solution supports data, voice and video
equipment to access the internet at greatest speed

and convenience. Focused on cost
sensitive market segment, Amazon
-
SE is an ideal ch
oice for broadband users

from residential
to SOHO (Small Office/Home Office) environments.
