Description
The Si3038 is an integrated direct access arrangement (DAA) chipset that
provides a digital, programmable line interface to meet global telephone
line requirements. Available in two 16-pin small outline packages (AC’97
interface on Si3024 and phone-line interface on Si3014), 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 Si3038
dramatically reduces the number of discrete components and cost
required to achieve compliance with global regulatory requirements. The
Si3024 complies with the AC’97 2.1 specification.
