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

GENERAL DESCRIPTION The VSC7177 is a Serial ATA and Serial Attached SCSI multiplier/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 storage

增强型2:1端口选择器，用于串行ATA和串行连接SCSI

VSC7177是一款串行ATA和串行连接SCSI分配器/缓冲器，可为1.5Gbps和3.0Gbps链路实现2:1端口选择功能。对于冗余、负载分配非常关键的高可靠性存储子系统，这项功能非常适合双主机(例如I/O控制器)必须连接单端口磁盘驱动器的应用。I/O控制器的输出复用到串行ATA或串行连接SCSI驱动器；串行ATA驱动器的输出经过缓存，复制到I/O控制器。从一个I/O控制器切换至另一个时，串行ATA链路必须使用带外数据(OOB)信号重新初始化，这将通过VSC7177透明传输。VSC7177提供驱动远距离背板和外部电缆所需的预加重、高输出摆幅，并具有可编程接收灵敏度。\n 可通过驱动外部I/O \n• 用于串行ATA (SATA)和串行连接SCSI (SAS)链路的2:1端口选择器 \n• 符合1.5Gbps (具备3.0Gbps能力)串行ATA 1.0规范 \n• 单边带端口选择 \n• 符合串行ATA II：端口选择规范1.0，包括容错控制 \n• 透明传输，易于通过串行ATA模板测试 \n• 可编程接收灵敏度 \n• 带预加重的高输出摆幅 \n• 兼容于前期设计(VSC7173和VSC7175)，提供增强的互联性和信号预加重 \n• 0.6W至0.8W功耗(取决于工作模式) \n• 3.3V供电 \n• 32引脚7mm x 7mm QFP-N封装;
