Abstract
A broadband digital communications link, protocol and related I/O circuits are provided which use an embedded control channel and a frame structure for transferring control information between different sections of a broadband system, including within a personal computer. A dedicated bus within the personal computer is used to support a variety of devices using the broadband link, and clocking is performed with a combination of bit clocks and frame clocks that are adjustable to accommodate needs of disparate types of data, including data for an xDSL communications path, xDSL samples from different analog codecs for xDSL modems, and ATM cells for an ATM interfaces. The I/O circuits include multiple bus interfaces to make them more flexibly integrated into a variety of application environments.
