USB Combi HUB
7*USB + 2*PS/2 + 1*Serial (RS232, DB9)
USB Combi-HUB OVERVIEW
The USB Compound Hub and
peripheral controller is specifically designed for implementing a wide
range of USB hub devices including those with embedded functions such
as Ir remote controls, IrDA and wireless communications, monitor controllers
etc.. The device includes the USB repeater and hub controller blocks
together with an embedded EMCU micro-controller and many associated
peripheral blocks to perform the embedded functions. Included is support
for legacy devices such as PS/2 keyboards and mice, serial and parallel
ports and a master/slave Access Bus ( I2C ) controller for monitor applications.
Firmware is in a low-cost external OTP ROM which allows maximum flexibility
for many different product configurations.
With its 7 downstream
ports and support for self powered or bus powered power sources and
gang switched or per-port switched USB power management the USB Compound
Hub represents a very wide ranging and flexible solution for most USB
hub requirements whilst its low external part count keeps manufacturerp
roduct cost to a minimum.
The USB Compound Hub
wide ranging capabilities make it the ideal choice for application areas
such as stand-alone hub boxes ( self or bus powered ) with value added
functions such as Ir multi-media wireless remote and game-pad controllers,
USB monitor-hubs with extended Ir capabilities, USB keyboard hubs etc.
The USB Compound Hub uses 3.3 volt process technology which lowers power
consumption and reduces electrical noise emissions thus making it easier
for products using this device to conform to FCC and CE emission requirements.
