摘要：A simple clock source synchronous DDR data transfer mechanism may becombined with static bus state signaling to replace a complex bus (e.g. USB) with an easyto implement digital serial interconnect bus. This may eliminate various pull-up/pull-down resistors required in USB, and enable the interconnect bus to operate with little or
no leakage current when the bus is in an idle state, or data transmission state. Allrequired functionality may be implemented using only two signal pins. The interconnectbus may also enable silicon solutions for high speed USB that do not require a PLL, sincethe clock may be provided by the transmission source and may thus not need to berecovered from the serial data stream. The digital serial interconnect bus may provide aneasy reuse mechanism for USB silicon by enabling a designer to remove the analog PHYand replace it with a serial digital I/O transfer mechanism, while retaining the IP's USBtimers, and other protocol specific features.
