Abstract
High-speed data communication devices, e.g., repeaters, interfacing between a host and a peripheral operate such that high-speed components except for a host-side squelch detector are set or maintained in a deactivated state during an idle period of a micro frame. In an example, a start of a micro frame is detected on a data bus during a first time period. In a second time period after the first time period, the high-speed communication device determines whether at least one data packet is contained in the micro frame. When it is determined during the second time period that no data packet is contained in the micro frame, active components, except a squelch detector, are controlled to be inactive during a third time period after the second time period.
