asynchronous reset input; when reset is active, the internal
switch to the 1.5 k
external resistor is opened, and all pins
DPn and DMn are three-state; it is recommended that you
connect to V
BUS
through an RC circuit; refer to the
schematics in the ISP1520 Hub Demo Board User’s Guide
analog or digital overcurrent detect selection input; a LOW
selects the digital mode and a HIGH (3.3 V) selects the
analog mode
crystal oscillator input (12 MHz)
crystal oscillator output (12 MHz)

test pin; connect to 3.3 V
analog supply voltage 1 (3.3 V)
ground supply
crystal and PLL supply voltage 4 (3.3 V)
ground supply
downstream facing port 3 D

no overcurrent protection selection input; connect this pin to
HIGH (3.3 V) to select no overcurrent protection; if no
overcurrent is selected, all OCn_N pins must be connected
to V
