Signal Description
OSC1
Oscillator Input. Input to the inverting 6 MHz oscillator
amplifier.
OSC2
Oscillator Output. Output of the inverting oscillator
amplifier.
LFT
PLL Filter. For proper operation of the PLL, this pin should
be connected through a 2.2 nF capacitor in parallel with a
100
resistor in series with a 10 nF capacitor to ground
(VSS).
SELF/BUS
Hub Power Mode. Input signal that sets the bus or self-
powered mode operation. A high on this pin enables the
self-powered mode, a low enables the bus-powered mode.
LPSTAT
Local Power Status. In the self-powered mode, this is an
input pin that should be connected to the local power sup-
ply through a 47k
resistor. The voltage on this pin is used
by the chip for reporting the condition of the local power
supply. In the bus-powered mode, this pin is not used.
DP0
Upstream Plus USB I/O. This pin should be connected to
CEXT through an external 1.5k
pull-up resistor. DP0 and
DM0 form the differential signal pin pairs connected to the
Host Controller or an upstream Hub.
DM0
Upstream Minus USB I/O.
DP[1:4]
Port Plus USB I/O. This pin should be connected to VSS
through an external 15k
resistor. DP[1:4] and DM[1:4] are
the differential signal pin pairs to connect downstream USB
devices.
DM[1:4]
Port Minus USB I/O. This pin should be connected to VSS
through an external 15k
resistor
