Pin Function
System Interface Supply Voltage: Used to provide reference
supply voltage for system I/O interface signaling.
Edge Rate Control: A logic HIGH operates at edge rates for “full
speed” operation. A logic LOW operates edge rates for “low
speed” operation.
Receive Data: Output for USB differential data.
If OE# = 1, VP = Receiver output (+)
If OE# = 0, VP = Driver input (+)
If OE# = 1 VM, = Receiver output (-)
If OE# = 0, VM = Driver input (-)
CONNECT (Input): Controls state of VPU. Refer to VPU pin
description for detail.
Ground Reference.
Suspend: Active-High. Turns off internal circuits to reduce supply
current.
Output Enable: Active-Low. Enables the transceiver to transmit
data onto the bus. When not active, the transceiver is in the
receive mode.
Differential data lines conforming to the USB standard.
3.3V Reference Supply Output: Requires a minimum 0.1µF
decoupling capacitor for stability, 1µF recommended.4
Pull-up Supply Voltage Output: Used to connect 1.5kΩ pull-up
speed detect resistor. If CON = 1, VPU is high impedance.
If CON = 0, VPU = 3.3V.
USB Bus Supply Voltage: Used to power USB transceiver and
internal circuitry.
No connect.
