End of packet (EOP)
SE0 for approximately 2 bit times⁽¹⁾
followed by a J state for 1 bit time
SE0 for ≥ 1 bit time⁽²⁾ followed by a
J state for 1 bit time

D+ and D– < V_IL (max) for ≥ 8µs
Notes:
1. The width of EOP is defined in bit times relative to the speed of transmission.
2. The width of EOP is defined in bit times relative to the device type receiving the EOP. The bit time is approximate.
