AT43312A
1255G–USB–05/06
The Serial Interface Engine’s
Tasks are:
Manage the USB communication protocol
USB signaling detection/generation
Clock/Data separation, data encoding/decoding, CRC generation/checking
Data serialization/de-serialization
The Hub Repeater is
Responsible for:
Providing upstream connectivity between the selected device and the Host
Managing connectivity setup and tear-down
Handling bus fault detection and recovery
Detecting connect/disconnect on each port
The Hub Controller is
Responsible for:
Hub enumeration
Providing configuration information to the Host
Providing status of each port to the Host
Controlling each port per Host command
