Description
The Si3035 is an integrated direct access arrangement (DAA) chipset that
provides a digital, lo w-cost, solid-state in terface to a t elephone lin e.
Available in two 16-pin small outline packages, it eliminates the need for an
analog front end (AFE), an isolation transformer, relays, opto-isolators, and
a 2- t o 4-wire hybrid. T he Si3 035 dra matically red uces the num ber of
discrete c omponents an d c ost required t o achieve c ompliance with F CC
Part 6 8. The Si3 035 int erfaces d irectly to s tandard modem DSPs and
supports all F CC an d J ATE o ut-of-band noi se req uirements. International
support is provided by the pin compatible Si3034.
