The Si3036 is an integrated direct access arrangement (DAA) chipset that provides a digital, programmable interface to a telephone line. Available in two 16-pin small outline packages (AC'97 interface on Si3024 and phone-line interface on Si3012), the chipset eliminates the need for an analog front end (AFE), an isolation transformer, relays, opto-isolators, and a 2- to 4-wire hybrid. The Si3036 dramatically reduces the number of discrete components and cost required to achieve compliance with FCC Part 68 and JATE. The Si3024 complies with the AC'97 2.1 specification.
