ESCRIPTION
The 303DL chip set is an integrated direct digital access
arrangement (DAA) chip set that provides a digital, low-
cost, solid-state interface to a telephone line. 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- to 4-wire hybrid. The
303DL dramatically reduces the number of discrete
components and cost required to achieve compliance
with FCC Part 68. The 303DL interfaces directly to
standard modem DSPs and supports all U.S. FCC and
JATE out-of-band noise requirements.
