    摘要: A receiver for a serial link port that is enhanced by a clock-data-recovery loop connected to the forwarded clock signal lane. The receiver includes a phase interpolation means controlled by a phase position logic which gets its update signal from local phase update signals of the clock-data-recovery loop via a digital low pass filter. The receiver also provides a global phase update source selection logic to control which clock-data-recovery loop is distributing phase update information, and which clock-data-recovery loop is receiving phase update information based on the clock analysis block.

The communication interface device includes high-speed sampling logic to capture high-speed data from the high-speed bus using a high-speed sampling clock and SBC sampling logic to capture SBC samples from the high-speed bus using an SBC sampling clock. The SBC sampling clock is slower than the high-speed sampling clock. The communication interface device also includes an SBC finite state machine (FSM) to detect a received SBC command in response to a static pattern persisting for a predetermined number of the SBC samples and command decoding logic to decode the received SBC command.
