Functional Description
The USB1T1103 transceiver is designed to convert CMOS
data into USB differential bus signal levels and to convert
USB differential bus signal to CMOS data.
To minimize EMI and noise the outputs are edge rate con-
trolled with the rise and fall times controlled and defined for
full speed data rates only (12Mbits/s). The rise, fall times
are balanced between the differential terminals to minimize
skew.
The USB1T1103 differs from earlier USB Transceiver in
that the V

terminals are now I/O terminals
rather than discrete input and output terminals. Table 1
describes the specific terminal functionality selection. Table
2 and Table 3 describe the specific Truth Tables for Driver
and Receiver operating functions.
The USB1T1103 also has the capability of various power
supply configurations, including a disable mode for V
CCIO
disconnected, to support mixed voltage supply applications
(see Table 4) and Section 2.1 for detailed descriptions.
Functional Tables
TABLE 1. Function Select
Note 1:
Signal levels is function of connection and/or pull-up/pull-down resistors.
Note 2:
For SUSPND
HIGH mode the differential receiver is inactive and the output RCV is forced LOW. The out-of-suspend signaling (K) is detected via
the single-ended receivers of the V
