Abstract
The invention discloses a method for improving SATA signal integrity and relates to an SATA signal transmission technology. A Redriver IC is arranged between an SATA controller and an SATA connector, then, the SATA connector is externally connected with a hard disk or other SATA devices; attenuated SATA signals are subjected to secondary amplification and repairing through the Redriver IC. The signal integrity of the SATA signals is guaranteed, no problems can be caused when the lengths of externally connected Cables are different, and the reliability of the externally connected SATA hard disk is improved.
Description
Technical field
The present invention relates to SATA signal transmission technology, a kind of method improving SATA signal integrity degree.
Background technology
Signal integrity refers to signal quality on the transmit path, and transmission path can be common metal wire, can be optics, it is also possible to be other mediums.Signal has good signal integrity and refers to when at needs when, has the voltage level numerical value that must reach.The signal integrity of difference is not caused by a certain single factors, but in design on board level, many factors causes jointly.Generally, in server system or PC, being all motherboard design, transmission signal is all copper cash.General server or PC all can have one or more SATA interface, connect the equipment of one or more hard disk and other SATA interface.
Along with universal, the development of various data clouds of PC, the quantity of server and PC gets more and more.At present the main board function of server or PC gets more and more, and the SATA interface on mainboard is more and more remote from control chip, and the most present high speed signal is more and more, and the crosstalk to the SATA signal on mainboard also gets more and more.Cable line also can be used on hard disk or other equipment to connect additionally due to SATA interface is received, the longest integrity degree on signal of Cable line affects the biggest.When SATA signal is disturbed, hard disk or other equipment being connected to SATA interface can be caused to occur abnormal, the various problems such as cause that server system goes wrong.
Summary of the invention
The present invention is directed to current needs and the weak point of prior art development, it is provided that a kind of method improving SATA signal integrity degree.
A kind of method improving SATA signal integrity degree of the present invention, the technical scheme solving the employing of above-mentioned technical problem is as follows: the described method improving SATA signal integrity degree, one Redriver IC is mainly set between SATA controller and SATA connector, then by SATA connector external hard drive or other SATA device；By Redriver IC, the SATA signal of decay is carried out secondary amplify and repair, improve the integrity of SATA signal.
Preferably, described SATA connector also can external Cable line, described hard disk or other SATA device are connected on SATA connector by Cable line.
Preferably, described Redriver IC uses the PI3EQX3851B of PERICOM.
The method of a kind of SATA of improvement signal integrity degree of the present invention compared with prior art has the beneficial effect that the present invention increases a Redriver IC between the controller and the adapter of SATA of SATA, the SATA signal of decay is amplified again, ensure the signal integrity degree of SATA signal, and do not have any problem when ensure that the Cable line that spreading degree differs outside, improve the reliability of external SATA hard disc, improve the reliability of SATA device, it is further able to ensure the reliability of product, and reduces the maintenance cost of product.
Figure of description
Accompanying drawing 1 is the schematic block diagram of the described method improving SATA signal integrity degree.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, a kind of method improving SATA signal integrity degree of the present invention is further described.
The proposed by the invention method improving SATA signal integrity degree, increases the IC of a redriver in the middle of the controller of SATA and the adapter of SATA, the SATA signal of decay carries out secondary and amplifies and repair.Method provided by the present invention can improve the integrity degree of SATA signal, improves the reliability of external SATA hard disc, thus ensures the stability of system disk and associated server and PC product, improves product quality.
Embodiment:
A kind of method improving SATA signal integrity degree described in the present embodiment, mainly arranges a Redriver IC, then by SATA connector external hard drive or other SATA device between SATA controller and SATA connector；By Redriver IC, the SATA signal of decay is carried out secondary amplify and repair, so improve the integrity of SATA signal, and then improve the external hard disk of SATA connector or the reliability of other SATA device.
Improve in the method for SATA signal integrity degree described in the present embodiment, as shown in Figure 1, described SATA connector also can external Cable line, described hard disk or other SATA device are connected on SATA connector by Cable line.In this enforcement, due to SATA connector external Cable line, described Redriver IC to be arranged near SATA connector one end, it is ensured that SATA connector can ensure that the intensity of SATA signal after connecting Cable line.
Improve in the method for SATA signal integrity degree described in the present embodiment, one Redriver IC is set between described SATA controller and SATA connector, described Redriver IC uses the PI3EQX3851B of PERICOM, the signal of decay can be amplified again by this Redriver IC, it is ensured that the signal integrity degree of SATA signal.
Above-mentioned detailed description of the invention is only the concrete case of the present invention; the scope of patent protection of the present invention includes but not limited to above-mentioned detailed description of the invention; suitably change that it is done by any that meet claims of the present invention and any person of an ordinary skill in the technical field or replace, all should fall into the scope of patent protection of the present invention.
