USB MultiSwitch Hub
Highlights USB 2.0 Compatible 4-Port Hub with two
upstream host port connections
-Provides electronic reconfiguration and reassignment of any of its 4 downstream ports
to either of two upstream host ports (“on-thefly”)
-Allows multiple USB hosts to share peripherals and enables a user to dynamically assign
host ownership
-Embedded Mode -8 (predefined, OEM
programmable) configurations for port assignment
are selectable via three external control signals
-Peripheral Mode -Dedicated select pin for every
downstream port (total of 4), selectable edge or level
triggered in order to support a wide range of possible
switch configurations and styles -Each host has a dedicated Single Transaction Translator (Single-TT) for supporting FS/
LS devices, or can also operate in Multi-TT
mode where each downstream port has a
dedicated Transaction Translator. Downstream ports can be disabled or defined as
non-removable Switching hub can be configured as compound
device for support of �embedded’ USB peripherals Multiple LED modes for maximum implementation
flexibility
-USB Mode -2 Single-color LEDs for each
downstream port (total of 8 LEDs) …
