摘要： 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.

摘要： A digital communications link and protocol is disclosed in connection with a digital controller section and an analog CODEC section of an xDSL modem mounted on a computer motherboard. The xDSL modem is configured on the motherboard with the digital and analog sections separated so as to improve noise performance in the analog front end sections. The digital communications link is characterized by an improved architecture which includes optimally selected data signal lines, an embedded control channel, a flexible data clocking mechanism, capability for providing multiple data channels, and a preselected operational and/or control word format. These features allow a computer motherboard fitted with the digital communications link to be easily adaptable and usable with a number of different combinations of digital and analog circuits associated with xDSL modems.
