POWER, GROUND, and NO CONNECTS
48 MHz Clock Input Selection
48 MHz external input clock select. When the hub is clocked from an external
clock source, this pin selects either 24 MHz or 48 MHz mode.
‘0’ = 24 MHz
‘1’ = 48 MHz
VDD Core Regulator Filter Capacitor
This pin must have a 1.0 μF (or greater) ±20% (ESR <0.1 Ω) capacitor to
VSS.
3.3 V Power
PLL Regulator Filter Capacitor
This pin must have a 1.0 μF (or greater) ±20% (ESR <0.1 Ω) capacitor to
VSS.
Ground Pad / ePad
The package slug is the only VSS for the device and must be tied to ground
with multiple vias.
No Connect
No signal or trace should be routed or attached to these pins.
