Product Description
The AX88760 is a high performance and highly integrated USB/Ethernet and USB/USB connectivity solution which
contains an USB 2.0 hub, three downstream USB 2.0 transceivers, an upstream USB 2.0 transceiver, a 10/100M Ethernet
PHY, a 10/100M Ethernet MAC, a EEPROM controller, and a 24KB SRAM. The AX88760 is targeted for many
applications such as desktops, notebook PC’s, Ultra-Mobile PC’s, docking stations, game consoles, multifunction
printers, digital-home appliances, and any embedded system using a standard USB port.

2.2.3 Non-removable port setting
For a compound application or embedded system, downstream ports that always connected inside the
system can be set as non-removable based on the state of corresponding status LED, pin GREEN 1~3. If
the pin is pulling high during the initial stage (power on reset) the corresponding port will be set as
non-removable. (Feature Limitation: GREEN1 & GREEN2 should evade configuring both port #1 and #2
as non-removable by this strapping feature)
2.2.4 Clock source setting
The HUB controller supports optional 12/27 MHz clock source by SEL27_N pin.
Name
SEL27_N
Description
0: XI pin clock source can be 27MHz OSC-in
1: XI/XO clock source is 12MHz XTAL or OSC-in
