DESCRIPTION

PIN NO.

NAME(1)

RGT

RTZ

Output enable (CMOS level with respect to VCC(I/O), active LOW). Enables

the transceiver to transmit data on the USB bus input pad. Push pull,

CMOS.

Differential data receiver (CMOS level with respect to VCC(I/O)). Driven LOW

when input SUSPND is HIGH. The output state of RCV is preserved and

RCV

stable during an SE0 condition output pad. Push pull, 4-mA output drive,

CMOS.

Single-ended D+ receiver (CMOS level with respect to V). For external

detection of single-ended zero (SE0), error conditions, speed of connected

device. Driven HIGH when no supply voltage is connected to VCC(5.0) and

Vreg(3.3) output pad. Push pull, 4-mA output drive, CMOS.

Single-ended D– receiver (CMOS level with respect to VCC(I/O)). For

external detection of single-ended zero (SE0), error conditions, speed of

connected device. Driven HIGH when no supply voltage is connected to

VCC(5.0) and Vreg(3.3) output pad. Push pull, 4-mA output drive, CMOS.

Suspend (CMOS level with respect to VCC(I/O)). A HIGH level enables

SUSPND

low-power state while the USB bus is inactive and drives output RCV to a

LOW-level input pad. Push pull, CMOS.

Mode (CMOS level with respect to VCC(I/O)). A HIGH level enables the

differential input mode (VPO, VMO), whereas a LOW level enables a

MODE

single-ended input mode (VO, FSE0). See Table 5 and Table 6 input pad.

Push pull, CMOS.
