Hi-Speed Universal Serial Bus hub controller

Rev. 02 — 04 May 2004

Product data

1. General description

The ISP1520 is a stand-alone Universal Serial Bus (USB) hub controller IC that

complies with Universal Serial Bus Speciﬁcation 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 IC 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 conﬁgured 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.
