REFSEL[0]

Input,

CMOS

N/A

This signal, along with REFSEL[1] and

REFSEL[2]

selects one of the available

reference frequencies as defined in

Table 5-10.

Note: This signal must be tied to VDDIO

when in ULPI 60MHz REFCLK IN mode.

REFSEL[1]

Input,

CMOS

N/A

This signal, along with REFSEL[0] and

REFSEL[2]

selects one of the available

reference frequencies as defined in

Table 5-10.

Note: This signal must be tied to VDDIO

when in ULPI 60MHz REFCLK IN mode.

N/A

ULPI bi-directional data bus.

REFSEL[2]

Input,

CMOS

N/A

This signal, along with REFSEL[0] and

REFSEL[1]

selects one of the available

reference frequencies as defined in

Table 5-10.

N/A

D- pin of the USB cable.

VDD33

Power

N/A

3.3V Regulator Output. A 2.2uF (<1 ohm

ESR) bypass capacitor to ground is

required for regulator stability. The bypass

capacitor should be placed as close as

possible to the USB3320.
