1. General description
The ISP1561 is a Peripheral Component Interconnect (PCI)-based, single-chip Universal
Serial Bus (USB) Host Controller. It integrates two Original USB Open Host Controller
Interface (OHCI) cores, one Hi-Speed USB Enhanced Host Controller Interface (EHCI)
core, and four transceivers that are compliant with Hi-Speed USB and Original USB. The
functional parts of the ISP1561 are fully compliant with
Specification”,
“Enhanced Host Controller Interface Specification for Universal Serial
Local Bus
Specification”.
Integrated high performance USB transceivers allow the ISP1561 to handle all Hi-Speed
USB transfer speed modes: high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed
(1.5 Mbit/s). The ISP1561 provides four downstream ports, allowing simultaneous
connection of USB devices at different speeds.
The ISP1561 provides three downstream port status indicators, GoodLink along with
green and amber LEDs, to allow user-rich messages of the root hub downstream ports
status, without requiring detailed port information to be reflected in internal registers.
The ISP1561 is fully compatible with various operating system drivers, such as Microsoft
Windows standard OHCI and EHCI drivers that are present in Windows 98 Second
Edition (SE), Windows Millennium Edition (Me), Windows XP and Windows 2000.
The ISP1561 directly interfaces to any 32-bit, 33 MHz PCI bus. It has 5 V tolerant PCI pins
that can source 3.3 V. The PCI interface fully complies with
Specification”.
The ISP1561 is ideally suited for use in Hi-Speed USB host-enabled motherboards,
Hi-Speed USB host PCI add-on card applications, mobile applications, and embedded
solutions.
To facilitate motherboard development, the ISP1561 can use the available 48 MHz clock
signal to reduce the total cost of a solution. To reduce the ElectroMagnetic Interference
(EMI), however, it is recommended that the 12 MHz clock is used in PCI add-on card
designs.
