System Interface Supply Voltage (1.6V to 3.6V). Provides reference supply
voltage for system I/O interface signals.
Edge Rate Control. A logic HIGH operates at edge rates for “fullspeed”
operation. A logic LOW operates edge rates for “lowspeed” operation.
Receive Data. Output for USB differential data. (see
If OE# = H, VP = Receiver output (+)
If OE# = L, VP = Driver input (+) (see
If OE# = H, VM = Receiver output (-)
If OE# = L, VM = Driver input (-) (see
CONNECT (input). Controls state of V
Ground Reference
Suspend (active-high). Turns off internal circuits to reduce supply current.
Output Enable (active-low). Enables transceiver data transmission onto the bus.
When not active, the transceiver is in the receive mode. (see
Differential data lines. (see
3.3V Reference Supply Output. Requires a 1.0µF decoupling capacitor for
stability.
Pull-up Supply Voltage Output. Used to connect 1.5kΩ pull-up speed detect
resistor. If CON = 0, V
USB Bus Supply Voltage (4V to 5.5V). Supplies power to the USB transceiver
