US11/881,281 USB integrated bidirectional digital isolator channel across an interface between two USB devices Alternatively, the physical layer component 450 a may be split, or both components 450 a and 450 b may be split.Äetecting completion of the transmission of the digital signal by monitoring the digital signal for a transition from a non-idle state to an idle state. 5, into the CDR component 510 and the XCVR component 520. In some applications, it may be necessary or beneficial to split the physical layer component 450 b, as shown in FIG. The CDR component 510 and the XCVR component 520 together may form the physical layer component 450 b shown in FIG. The isolator channels 430 may isolate and transmit the USB digital signal in the determined direction as described above with relation to FIG. However, the USB hub controller 420 continues to inherently provide the USB digital signal direction and determine the transmission direction to convey to the isolator channels 430. In this embodiment, the isolator channels 430 are connected between the CDR component 510 and the XCVR component 520. 5, a second high speed USB isolator component 500 includes a physical layer component 450 a as well as a clock data recovery (CDR) component 510 and a transceiver (XCVR) component 520.
