The MAX4986CTO+ from Maxim Integrated Products is a SAS/SATA single lane 2:1/1:2 multiplexer/demultiplexer plus redriver with equalization in 42 pin TQFN package. This multiplexer/demultiplexer equalizes and redrives SAS/SATA or SATA-only signals up to 6.0Gbps and operates from a single +3.3V supply. It features independent input equalization and output preemphasis and enhances signal integrity at the receiver by equalizing the signal at the input and establishing preemphasis at the output of the device. SAS/SATA and SATA-only out-of-band (OOB) signalling is supported using high-speed amplitude detection on the inputs and squelch on the corresponding outputs. Inputs and outputs are internally 50 ohm terminated and must be AC coupled to the SAS/SATA controller IC and SAS/SATA device. It is used at PC servers, workstations, desktops and docking stations.
