RGT RTZ PW RTZ
Output enable (CMOS level with respect to V
CC(I/O)
, active LOW). Enables
OE 1 1 3 1 I the transceiver to transmit data on the USB bus input pad. Push pull,
CMOS.
Differential data receiver (CMOS level with respect to V
CC(I/O)
). Driven LOW
when input SUSPND is HIGH. The output state of RCV is preserved and
RCV 2 2 4 2 O
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
VP 3 3 5 3 O
device. Driven HIGH when no supply voltage is connected to V
CC(5.0)
and
V
reg(3.3)
output pad. Push pull, 4-mA output drive, CMOS.
Single-ended D– receiver (CMOS level with respect to V
CC(I/O)
). For
external detection of single-ended zero (SE0), error conditions, speed of
VM 4 4 6 4 O
connected device. Driven HIGH when no supply voltage is connected to
V
CC(5.0)
and V
reg(3.3)
output pad. Push pull, 4-mA output drive, CMOS.
Suspend (CMOS level with respect to V
CC(I/O)
). A HIGH level enables
SUSPND 5 5 7 5 I 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 V
CC(I/O)
). A HIGH level enables the
differential input mode (VPO, VMO), whereas a LOW level enables a
MODE 6 6 I
single-ended input mode (VO, FSE0). See Table 5 and Table 6 input pad.
Push pull, CMOS.
(1) Terminal names with an overscore (e.g., NAME) indicate active LOW signals.
