Description
crystal oscillator input (12 MHz)
crystal oscillator output (12 MHz)
ground supply
downstream facing port 2 D connection (analog)
downstream facing port 2 D+ connection (analog)
test pin; connect to 3.3 V
supply voltage 1 (3.3 V) (analog)
ground supply
supply voltage 4 (3.3 V) (crystal and PLL)
ground supply
downstream facing port 3 D connection (analog)
downstream facing port 3 D+ connection (analog)
supply voltage 2 (3.3 V) (transceiver)
ground supply
downstream facing port 4 D connection (analog)
downstream facing port 4 D+ connection (analog)
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
output — green LED port indicator (open-drain) for
downstream facing port 4
