描述 Description

The Si3066 is an integrated direct access arrangement (DAA) for use with an integrated DAA system-side module. It includes a V.32 quality codec, dc termination, ac termination, and an integrated hybrid, eliminating the need for an analog front end (AFE), isolation transformer, relays, optoisolator, and a 2- to 4-wire hybrid. It interfaces directly to the integrated system-side module and features Silicon Laboratories’ patented isolation technology. The Si3066 dramatically reduces the board space, component count, and cost required to implement a DAA compliant with the regulatory requirements of 49 different PTTs including FCC, JATE, China, and Korea.
