Abstract
The utility model relates to an equipment of an integrated concentrator and an integrated driver electronic component interface. The utility model comprises a universal series bus concentrator controller for controlling the operation of a universal series bus, a universal series bus upper serial port for coupling to the universal series bus concentrator controller, a universal series bus lower serial port for coupling to the universal series bus concentrator controller, and a transforming bridge from the universal series bus to the integrated driver electronic component, which is used for coupling to the universal series bus concentrator controller and wherein comprises an interface equipment for external device communication. The design simplifies the integrated concentrator and the integrated driver electronic component interface.
Description
Technical field
The utility model belongs to the interface group device of a kind of integrated hub (HUB) and integrated drive electronic unit (IDE) interface.
Background technology
At present, circuit design or integrated circuit board that integrated universal serial bus (USB) HUB and ATA/ATAPI (interface standard of IDE equipment) interface also do not occur.USB1.1 standard transmission speed originally is the highest has only 12Mbit/s, and the IDE devices transfer rate of ATA/ATAPI interface is all more than 33Mbyte/s, so both inconsistencies, people can not be with both combinations.Along with the release of USB2.0, the transfer rate of USB has significantly lifting, reaches 480Mbit/s, and integrated both advantages that will make of USB2.0 HUB and ATA/ATAPI interfacing equipment are more obvious.
Technical scheme
The purpose of this utility model is exactly to realize USB HUB function and storage facilities function on little integrated circuit board, realizes that power supply is shared, the USB resource sharing.Give full play to both advantages.The USB HUB here is the equipment that one road usb signal is converted to the multichannel usb signal.And USB TO IDE BRIDGE is the equipment that usb signal is converted to IDE parallel port signal.
In order to realize above purpose, we have carried out integrated to USB HUB and USB TO IDE BRIDGE, make under the function realization condition volume minimum.
The device of integrated hub and integrated drive electronic unit interface comprises:
The universal serial bus concentrator controller is used to control the operation of USB (universal serial bus);
The USB (universal serial bus) up going port is coupled to the universal serial bus concentrator controller;
The USB (universal serial bus) down going port is coupled to the universal serial bus concentrator controller;
USB (universal serial bus) is coupled to the USB (universal serial bus) collection to integrated actuator electrical subassembly Bridge
Line device controller wherein, comprises interface arrangement, to communicate by letter with external equipment.
Wherein, described up going port comprises: reset circuit makes by switch and resistance to pull down to low level and realize; Impedance matching resistance and filter capacitor.
Wherein, described down going port comprises at least one USB mouth and drop-down resistance.
Wherein, described USB (universal serial bus) comprises pull-up resistor to integrated actuator electrical subassembly Bridge.
By integration USB 2.0 HUB functions and storage facilities function, realize that power supply is shared, the USB resource sharing, IDE equipment uses more flexible.Give full play to both advantages.
The drawing explanation
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the up going port circuit of USB HUB chip;
Fig. 3 is the down going port circuit of USB HUB;
Fig. 4 is the importation of USB to IDE bridge differential signal.
Embodiment
Signal as can be seen from Figure 1, the USB up going port comes out to arrive I/O BAY from main frame, at first be converted into several down going port through USBhub controller, one of them down going port is supplied with USB to IDE bridge, other down going port offers the user and uses, and optical storage device obtains data-signal from USB to IDE bridge.The outside 5V power supply in power supply aspect is directly supplied with USB HUB, USB to IDE bridge, optical storage device.Four-headed arrow is represented signal flow as shown in Figure 1, and unidirectional solid arrow is represented power supply stream.
As shown in Figure 2, this is the up going port circuit of USB HUB chip, and SYSRSTB PIN pin (15PIN) is a USB HUB CHIP reset circuit, makes SYSRST pull down to low level by switch and realizes.The differential signal input of up going port is DMU (69PIN), DPU (71PIN).R133 (connecting DMU and up going port joint), R134 (connecting DPU and up going port joint) is an impedance matching resistance, R50 (connecting DPU and PIN74 RPU) is a pull-up resistor, is used for discerning USBHUB when initialization USB HUB CHIP.The R24 (connecting RSDMU and DMU) that connects RSDMU (PIN68) is to be used for compatible USB1.1 FULL SPEED and LOW SPEED USB device with the R23 that is connected RSDPU (PIN72) (connecting DPU and RSDPU).C153 (connecting DP signal and ground), C157 (connecting DM signal and ground) is a filter capacitor.VBUS is the bus voltage of USB.
Fig. 3 is the down going port circuit of USB HUB, and wherein the DM that marks among the figure (PIN78), DP (PIN80) are the differential signals of supplying with USB TO IDE BIRDGE.Other 3 down going port DN2, DN3, DN4 provide three USB mouths that use to the user.Wherein R34 (connecting DM and ground) is drop-down resistance to R39 (being connected PIN98 and ground), and these resistance are essential when down going port connects USB device.R25 (connecting PIN80 and PIN81) is the equipment of compatible USB1.1 to the effect of R31 (being connected PIN98 and PIN99).
Fig. 4 is the importation of USB TO IDE BRIDGE differential signal.DP (PIN13), DM (PIN15) are the differential signals from USB HUB.R52 (connecting DP and PIN10 RPU) is a pull-up resistor, and R53 (connecting DM and PIN16 RSDM), R54 (are connected the equipment that (DP and PIN 12 RSDP) are used for compatible USB1.1.
