Features

such as staggered HDD spin-up, power management control, hot plug capability and support for legacy software. The XRS10L140 acts as a retimer, maintaining independent signaling domains between the drives themselves and the external interconnect. The high-speed serial input features selectable equalization adjustment and the high-speed serial output features selectable pre-emphasis to compensate for ISI (Inter-Symbol Interference) and increase maximum cable distances. XRS10L140 meets tight jitter.
