HS Differential Transmitter
The HS transmitter is always operated on the UTMI parallel interface. The parallel data on the interface is
serialized, bit stuffed, NRZI encoded, and transmitted as a dc output current on DP or DM, depending on
the data. Each line has an effective 22.5-
load to ground, which generates the voltage levels for
signaling.
A disconnect detector is also part of the HS transmitter. A disconnect on the far end of the cable causes
the impedance seen by the transmitter to double, thereby doubling the differential amplitude seen on the
DP/DM lines.
Table 7-6 lists the characteristics of the HS differential transmitter.
