USB1T1104

USB1T1104 Universal Serial Bus Peripheral Transceiver with Voltage Regulator August 2004 Revised August 2005 USB1T1104 Universal Serial Bus Peripheral Transceiver with Voltage Regulator General Description The USB1T1104 is an Universal Serial Bus Specification Rev 2.0 compliant transceiver. The device provides an USB interface for Full-Speed (12Mbit/s) USB applications. The USB1T1104 provides excellent flexibility, allowing differential and single ended inputs while an integrated voltage regulator sets the I/O level to 1.65V to 3.6V. Utilizing an integrated 5.0V to 3.3V voltage regulator, the part can be powered directly from the USB host (VBUS) to minimize the power consumed from the local sources while used in devices with low supply voltages. The USB1T1104 provides 15kV ESD protection on the USB bus pins (D/D). This eliminates the need for any external ESD devices while providing excellent protection to larger and more expensive ASICs and USB controllers.

When not active the transceiver is in the receive mode (CMOS level is relative to VCCIO) 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. Single-ended D receiver output VP (CMOS level relative to VCCIO): Used for external detection of SEO, error conditions, speed of connected device; Driven HIGH when no supply connected to VCC and VREG. Single-ended D receiver output Vm (CMOS level relative to VCCIO): Used for external detection of SEO, error conditions, speed of connected device; Driven HIGH when no supply connected to VCC and VREG. Suspend: Enables a low power state (CMOS level is relative to VCCIO). While the SUSPND pin is active (HIGH) it will drive the RCV pin to logic “0” state. MODE input (CMOS level is relative to VCCIO). A HIGH selects the differential input MODE (Vpo, Vmo) whereas a LOW enables the single-ended MODE (Vo, VFSEO) see Table 2 and Table 4 Supply Voltage for digital I/O pins (1.65V to 3.6V): When not connected the D and D pins are in 3-STATE.

Functional Description The USB1T1104 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. The rise, fall times are balanced between the differential pins to minimize skew. Table 1 describes the specific pin functionality selection. Table 2, Table 3, and Table 4 describe the specific Truth Tables for Driver and Receiver operating functions. The USB1T1104 also has the capability of various power supply configurations to support mixed voltage supply applications (see Table 5) and Power Supply Configurations and Options for detailed descriptions.

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. 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 pins are 3-STATE and the USB1T1104 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 10 P A) and VCCIO such that device is in low power (suspended) state. Pins 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 and VCC(5V) is connected. In this mode the D and D pins are 3-STATE and the device is in low power state. A summary of the Supply Configurations is described in Table 5. TABLE 5.
