The MAX14986 dual-channel redriver is designed to redrive one full lane of SAS or SATA signals up to 6.0GT/s (gigatransfers per second) and operates from a single +3.3V supply.
The MAX14986 features independent input equalization and output preemphasis. It enhances signal integrity at the receiver by equalizing the signal at the input and establishing preemphasis at the output of the device. SAS and SATA OOB (out-of-band) signaling is supported using high-speed amplitude detection on the inputs and squelch on the corresponding outputs. Inputs and outputs are all internally 50Ω terminated and must be AC-coupled to the SAS/SATA controller IC and SAS/SATA device.
The MAX14986 is available in a small 28-pin, 3.5mm x 5.5mm TQFN package with flow-through traces for ease of layout. This device is specified over the -40°C to +85°C extended operating temperature range.

Product Detail

The MAX14986 evaluation kit (EV kit) provides a proven design to evaluate the MAX14986 dual-channel buffer. The EV kit contains four sections: an application circuit, characterization circuit, and two calibration traces.
The application circuit (Figure 1a in the full data sheet) is designed to demonstrate the IC’s use in redriving Serial-Attached SCSI (SAS) and Serial ATA (SATA) signals. This section of the EV kit operates from an external +5V supply that is regulated by an on-board LDO to +3.3V, which powers the MAX14986 (U1) device. All traces in the application circuit are 100Ω differential controlled-impedance traces.
The characterization circuit (Figure 1b in the full data sheet) is provided for eye diagram evaluation using SMA connectors and 50Ω single-ended controlled-impedance traces. This section is powered by an external +3.3V supply.
