When not active the transceiver is in the receive mode (CMOS level is relative to VCCIO) 2 2 RCV O Receive Data Output: Non-inverted CMOS level output for USB differential Input (CMOS output level is relative to VCCIO). Driven LOW when SUSPN is HIGH; RCV output is stable and preserved during SE0 condition. 3 3 Vp/Vpo I/O Single-ended D receiver output VP (CMOS level relative to VCCIO): Used for external detection of SE0, error conditions, speed of connected device; Terminal also acts as drive data input Vpo (see Table 1 and Table 2). Output drive is 4 mA buffer. 4 4 Vm/Vmo I/O Single-ended D receiver output Vm (CMOS level relative to VCCIO): Used for external detection of SE0, error conditions, speed of connected device; Terminal also acts as drive data input Vmo (see Table 1 and Table 2).

While the SUSPND terminal is active (HIGH) it will drive the RCV terminal to logic “0” state. No Connect Supply Voltage for digital I/O terminals (1.65V to 3.6V): When not connected the D and D terminals are in 3-STATE. This supply bus is totally independent of VCC (5V) and VREG (3.3V), and must never exceed the VREG (3.3) voltage. For VCCIO disconnected the O/O terminals are HIGH Impedance and the VPU (3.3V) is turned off. Vbus monitor output (CMOS level relative to VCCIO): When Vbus ! 4.1V then Vbusmon HIGH and when Vbus 3.6V then Vbusmon LOW. If SUSPND HIGH then Vbusmon is pulled HIGH. Data , Data : Differential data bus conforming to the USB standard. Terminals are HIGH Impedance for bus powered mode when Vbus 3.6V. For ByPass Mode then HIGH Impedance when VREG/ Vbus VREG minimum. 10 11 NC No Connect — 12 NC No Connect 11 13 VREG (3.3V) Internal Regulator Option: Regulated supply output voltage (3.0V to 3.6V) during 5V operation; decoupling capacitor of at least 0.1 PF is required.

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 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 controlled 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 also has the capability of various power supply configurations, including a disable mode for VCCIO disconnected, to support mixed voltage supply applications (see Table 4) and Section 2.1 for detailed descriptions. The USB1T1103 differs from earlier USB Transceiver in that the Vp/Vm and Vpo/Vmo terminals are now I/O terminals Functional Tables TABLE 1.

Internally the circuitry limits leakage from D and D terminals (maximum 10 PA) and VCCIO such that device is in low power (suspended) state. Terminals Vbusmon and RCV are forced LOW as an indication of this mode with Vbusmon being ignored during this state. • Disable Mode: VCCIO is not connected. VCC is connected, or VCC and VREG are connected. 0V to 3.3V in this mode D and D are 3-STATE and VPU is HIGH Impedance (switch is turned off). The USB1T1103 allows external signals up to 3.6V to share the D and D bus lines. Internally the circuitry limits leakage from D and D pins (maximum 10PA). The three modes of power supply operation are: • Normal Mode: Regulated Output and Regulator Bypass 1. Regulated Output: VCCIO is connected and VCC(5.0) is connected to 5V (4.0V to 5.5V) and the internal voltage regulator then produces 3.3V for the USB connections. 2. Internal Regulator Bypass Mode: VCCIO is connected and both VCC(5.0) and VREG(3.3) are connected to a 3.3V source (3.0V to 3.6V). In both cases for normal mode the VCCIO is an independent voltage source (1.65V to 3.6V) that is a function of the external circuit configuration. • Sharing Mode: VCCIO is only supply connected. VCC and VREG are not connected. In this mode the D and D terminals are 3-STATE and the USB1T1103 allows external A summary of the Supply Configurations is described in Table 4. TABLE 4.
