Product Details

The MAX4952 quad-channel redriver is designed to redrive two full lanes of SAS or SATA signals up to 6.0GT/s (gigatransfers per second) and operates from a single +3.3V supply.

The MAX4952 features independent input equalization and output preemphasis. The MAX4952 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 MAX4952 is available in a small 42-pin, 3.5mm x 9mm TQFN package with flowthrough traces for ease of layout. This device is specified over the 0°C to +70°C operating temperature range.
