Table 1 describes the specific terminal functionality selection. Table 2 and Table 3 describe the specific Truth Tables for Driver and Receiver operating functions. 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 termi- Functional Tables Table 1.

Internally the circuitry limits leakage from D+ and D- terminals (maximum 10µA) 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. 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). 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 10µ A). 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. A summary of the Supply Configurations is described in Table 4. 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 Table 4.

Fairchild Semiconductor has evaluated this device using the IEC 6100-4-2 representative system model depicted in Figure 5. Under the additional standards set forth by the IEC, this device is also compliant with IEC 60749-26 (HBM) and IEC 60749-27 (MM). Since the differential terminals of a USB transceiver may be subjected to extreme ESD voltages, additional immunity has been included in the D+ and D- terminals without compromising performance. The USB1T1103 differential terminals have ESD protection to the following limits: ■ 15kV using the contact Human Body Model Additional ESD Test Conditions ■ 8kV using the Contact Discharge method as specified in IEC 61000-4-2 For additional information regarding our product test methodologies and performance levels, please contact Fairchild Semiconductor.
