General description
The ISP1520 is a stand-alone Universal Serial Bus (USB) hub controller IC that complies
with
Universal Serial Bus Specication Rev. 2.0. It supports data transfer at high-speed
(480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s).
The upstream facing port can be connected to a Hi-Speed USB host or hub, or to an
Original USB host or hub. If the upstream facing port is connected to a Hi-Speed USB
host or hub, then the ISP1520 will operate as a Hi-Speed USB hub. That is, it will support
high-speed, full-speed and low-speed devices connected to its downstream facing ports. If
the upstream facing port is connected to an Original USB host or hub, then the ISP1520
will operate as an Original USB hub. That is, high-speed devices that are connected to its
downstream facing ports will operate in full-speed mode instead.
The ISP1520 is a full hardware USB hub controller. All Original USB devices connected to
the downstream facing ports are handled using a single Transaction Translator (TT), when
operating in a cross-version environment. This allows the whole 480 Mbit/s upstream
bandwidth to be shared by all the Original USB devices on its downstream facing ports.
The ISP1520 has four downstream facing ports. If not used, ports 3 and 4 can be
disabled. The vendor ID, product ID and string descriptors on the hub are supplied by the
internal ROM; they can also be supplied by an external I2C-bus EEPROM or a
microcontroller.
The ISP1520 is suitable for self-powered hub designs.
An analog overcurrent detection circuitry is built into the ISP1520, which can also accept
digital overcurrent signals from external circuits; for example, Micrel MOSFET switch
MIC2026. The circuitry can be congured to trip on a global or an individual overcurrent
condition.
Each port comes with two status indicator LEDs.
Target applications of the ISP1520 are monitor hubs, docking stations for notebooks,
internal USB hub for motherboards, hub for extending Intel Easy PCs, hub boxes, and so
on.
