Transceiver macrocell architecture allowing upstream and downstream operation
View Patent ↗A system wherein a signal over a Universal Serial Bus (USB) interface is received by a receiver component. A mixed signal block utilizes a mixed signal interface to transmit the signal to a processor block.
1. A method of connecting a Universal Transceiver Macrocell Interface (UTMI) macrocell to a plurality of peripheral devices, the UTMI macrocell including a mixed signal block and a digital block, the mixed signal block including a Universal Serial Bus (USB) interface, and the digital block including a UTMI interface, the method comprising:
providing a mixed signal interface to connect the mixed signal block and the digital block;
providing a first connection to the peripheral devices via a hub controller connected to the UTMI interface; and
providing a second connection to the peripheral devices via a hub repeater connected to the mixed signal interface, wherein the second connection bypasses the hub controller.
2. A hub system for providing connection to a plurality of peripheral devices, the hub system comprising:
a Universal Transceiver Macrocell Interface (UTMI) macrocell including:
a mixed signal block including a Universal Serial Bus (USE) interface;
a digital block including a UTMI interface; and
a mixed signal interface connecting the mixed signal block and the digital block;
a hub controller connected to the USB interface;
a hub device including:
a transaction translator connected to the hub controller; and
a hub repeater connected to the mixed signal interface and operatively coupled to the transaction translator; and
a plurality of ports connected to the hub repeater, wherein the plurality of ports can be coupled to the plurality of peripheral devices.
3. A method of connecting a Universal Transceiver Macrocell Interface (UTMI) macrocell to a plurality of host controllers, the UTMI macrocell including a mixed signal block and a digital block, the method comprising:
providing a mixed signal interface to connect the mixed signal block and the digital block;
providing a first UTMI connection to a first host controller used in a first speed operational mode; and
providing a second UTMI connection to a second host controller used in a second speed operational mode,
wherein the UTMI macrocell can determine whether the first host controller or the second host controller is to be used.
4. A host system for providing connection to a plurality of host controllers, the host system comprising:
a Universal Transceiver Macrocell Interface (UTMI) macrocell including:
a mixed signal block including a Universal Serial Bus (USB) interface;
a digital block including a UTMI interface; and
a mixed signal interface connecting the mixed signal block and the digital block;
a first UTMI interface for connecting the UTMI macrocell to a first host controller; and
a second UTMI interface for connecting the UTMI macrocell to a second host controller.
