Abstract
The circuits and methods described herein provide technical solutions for technical problems facing USB links. To reduce or eliminate effects associated with a USB link entering a low-power mode, initial link acquisition may be performed while the spread-spectrum-clocking (SSC) modulation is disabled. Following the initial link acquisition, the SSC modulation may be enabled dynamically in a later stage. This delayed enablement of the re-timers provides improved performance over solutions in which the SSC modulation is constantly enabled, including reducing the complexity of the timing training process and enabling a faster USB link re-establishment. This reduced link acquisition period may enable the system to enter power saving modes more frequently, and may reduce latency involved in exiting power saving modes. This may maintain or improve total USB transmission speeds and may reduce USB-related power consumption for USB connected devices.
