1 / 54 page Rev. 1.2 12/00 Copyright © 2000 by Silicon Laboratories Si3035-DS12 Si3035 3 . 3 V FCC/JATE D IR ECT A C C ESS A R RAN G E MENT Features Complete DAA includes the following: Applications Description The Si3035 is an integrated direct access arrangement (DAA) chipset 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 Si3035 dramatically reduces the number of discrete components and cost required to achieve compliance with FCC Part 68. The Si3035 interfaces directly to standard modem DSPs and supports all FCC and JATE out-of-band noise requirements. International support is provided by the pin compatible Si3034.
