Enhanced 2:1 Port Selector and 1:2 Port Multiplier for Serial ATA and Serial Attached SCSI

GENERAL DESCRIPTION The VSC7173 is a Serial ATA and Serial Attached SCSI multiplexer and buffer that implements a 2:1 port selector function for 1.5 Gbps and 3.0 Gbps links. This function is used when dual hosts, such as I/O controllers, must access single-port disk drives in high availability st

增強(qiáng)型2:1端口選擇器和1:2端口分配器，用于串行ATA和串行連接SCSI

VSC7173是一款串行ATA和串行連接SCSI分配器、緩沖器，可為1.5Gbps和3.0Gbps鏈路實(shí)現(xiàn)2:1容錯(cuò)切換。對(duì)于冗余、負(fù)載分配非常關(guān)鍵的高可靠性存儲(chǔ)子系統(tǒng)，這項(xiàng)功能非常適合雙主機(jī)(例如I/O控制器)必須連接單端口磁盤驅(qū)動(dòng)器的應(yīng)用。I/O控制器的輸出復(fù)用到串行ATA或串行連接SCSI驅(qū)動(dòng)器；串行ATA驅(qū)動(dòng)器的輸出經(jīng)過緩存，復(fù)制到I/O控制器。從一個(gè)I/O控制器切換至另一個(gè)時(shí)，串行ATA鏈路必須使用帶外數(shù)據(jù)(OOB)信號(hào)重新初始化，這將通過VSC7173透明傳輸。VSC7173提供驅(qū)動(dòng)遠(yuǎn)距離背板和外部電纜所需的預(yù)加重、高輸出擺幅，并具有可編程接收靈敏度。\n 除了上述功能，VSC71 \n? 用于串行ATA (SATA)和串行連接SCSI (SAS)鏈路的2:1端口選擇器和1:2端口分配器 \n? 符合1.5Gbps (具備3.0Gbps能力)串行ATA 1.0規(guī)范 \n? 透明傳輸，易于通過串行ATA模板測試 \n? 可編程接收靈敏度 \n? 帶預(yù)加重的高輸出擺幅 \n? 兼容于VSC7175和VSC7177的設(shè)計(jì) \n? 0.7W功耗 \n? 3.3V供電 \n? 32引腳7mm x 7mm QFP-N封裝;
