PI2EQX6812ZHE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX6812 is a low-power SAS2, SATA, and XAUI signal ReDriver featuring four differential channels or two lanes. It supports data rates up to 6.5Gbps with adjustable receiver equalization, transmitter amplitude, de-emphasis, and input threshold levels. The device operates on a single 1.2V ± 0.05V supply, drawing typical active current of 95mA per channel. It includes 50-Ohm I/O termination, Mux/Demux capabilities, loop-back features, and full OOB support. Configuration is managed via pin strapping or I2C control. Power management includes standby mode (1mA typical) and automatic slumber mode (10mA per channel typical).
