1. A method of operating a high-speed data communication device, comprising:
detecting, on a data bus during a first time period, a start of a micro frame;
determining, during a second time period after the first time period, whether at least one data packet is contained in the micro frame; and
in response to determining that the micro frame discludes a data packet during the second time period, controlling active components, except a squelch detector, to be inactive during a third time period after the second time period.
