49.5.5.2 USB DC Characteristics
49.5.5.2.1 USB Transreceiver DC Characteristics
The DC electrical specifications of the USB Transreceivers in the EP80579 (USBp0,
USBn0, USBp1, USBn1) are compliant with the USB v2.0 specification from April 27,
2000 (refer to Section 7.3.2 Bus Timing/Electrical Characteristics for more
information).
External resistors are not required on USBp0, USBn0, USBp1 and USBn1. The chip
integrates the 15 KΩ pull-down and provides an output driver impedance of 45 Ohm,
which requires no external series resistor.
49.5.5.2.2 USB LVTTL Inputs DC Characteristics
The DC electrical specifications for the LVTTL inputs are described in Table 49-31.
