However, the USB is idle without being suspended, meaning there has been no USB activity for a frame interval (1 ms for low or full speed, or 0.125 ms for high speed), but short keep alive packets may be occurring within each frame to keep the USB from suspending. 2 The busy USB supply current values are for the device running at a fixed continuous data rate at 50% duty cycle, alternating J and K states. Supply current values are specified with a USB-compliant load present. 3 VUVLO3+ is the UVLO threshold, VDD1 or VDD2 rising. 4 These specifications are guaranteed by design and characterization. 5 CMTI is the maximum common-mode voltage slew rate that can be sustained while maintaining specification compliant operation. VCM is the common-mode potential difference between Side 1 and Side 2. The transient magnitude is the range over which the common mode is slewed. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. 6 Output voltage for UD+ or UD− > 0.8 VDD1 (other output ≤ 0.3 V), and output voltage for DD+ or DD− > 0.8 VDD2 (other output ≤ 0.3 V). 7 UD+ and UD− ≤ 0.3 V or DD+ and DD− ≤ 0.3 V.
