USB1T1103 Universal Serial Bus Peripheral Transceiver with Voltage Regulator © 2005 Fairchild Semiconductor Corporation www.fairchildsemi.com USB1T1103 Rev. 1.0.4 4 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 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...

USB1T1103 Universal Serial Bus Peripheral Transceiver with Voltage Regulator © 2005 Fairchild Semiconductor Corporation www.fairchildsemi.com USB1T1103 Rev. 1.0.4 5 Power Supply Configurations and Options 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)....
