AI Technical Summary

Problems solved by technology

[0004] Although there is already a USB3.0to SATA adapter (USB3.0 to SATA adapter) on the market, it is realized through a USB3.0to SATA bridge IC (USB3.0 to SATA bridge chip), which is relatively high in cost and not flexible enough in scalability
In addition, the existing eSATAp interface technology has strong limitations, and can only realize the conversion function between USB2.0 and eSATA

Embodiment Construction

[0016] refer to figure 1 , a combination interface of USB3.0 and eSATA proposed by the present invention includes a chip U1 and a connector J1.

[0017] The connector J1 is used to connect an external storage device, and is realized by using a USB3.0 interface. Connector J1 includes pins VBUS, D-, D+, GND, StdA_SSRX-, StdA_SSRX+, GND_DRAIN, StdA_SSTX-, StdA_SSTX+. Among them, VBUS is connected to the power supply, GND is grounded, D- and D+ are used to connect external USB2.0 storage devices to receive USB2.0 signals, StdA_SSRX-, StdA_SSRX+ are used to connect external USB3.0 storage devices to receive USB3.0 signals, StdA_SSTX -, StdA_SSTX+ is used to connect external USB3.0 storage devices to transmit USB3.0 signals.

[0018] In this embodiment, the USB3.0 interface specifically adopts USB3.0typeA (type A), and its interface specification is shown in Table 1.

Abstract

The invention provides a USB3.0 and eSATA combined interface comprising a chip and a connector. The connector is used for being connected with an external storage device; the chip is a multiplexer and comprises three address units and a level input end, a first address unit port A is connected with the connector, a second address unit port B is connected with a USB3.0 transceiving end, a third address unit port C is connected with an SATA3.0 transceiving end, and the level input end is used for a chip to be connected in to control level. The USB3.0 interface is taken as an eSATA signal and USB3.0 signal common interface, and the chip judges whether peripherals are eSATA or USB3.0 devices and switches out corresponding signals, so that the problem that one PC (personal computer) or laptop needs to be configured with multiple interfaces resulting in size increase is solved; thus, by the eSATA comb with USB3.0 interface, more space can be saved, and the PC is more compact and lighter.

Description

technical field [0001] The invention relates to the field of interface technology, in particular to a combined interface of USB3.0 and eSATA. Background technique [0002] At present, PCs and notebooks are equipped with USB3.0 interface to meet the needs of users for high-speed data storage. Currently commonly used storage device interfaces include USB3.0 (Universal Serial Bus 3.0, Universal Serial Bus 3), USB2.0 (Universal Serial Bus 2.0, Universal Serial Bus 2), eSATA (extenal Serial Advanced Technology Attachment, external serial Advanced Technology Attachment), eSATAp (Power eSATA, an external Serial Advanced Technology Attachment that can provide power) and so on. [0003] Contrary to the wide variety of storage device interfaces, PCs and notebooks are getting smaller and smaller, and there is not enough space to place a wide variety of storage interfaces, which leads to limitations in the choice of storage devices. In response to this situation, interface conversion ...
