Product Details
The MAX14980 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 MAX14980 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 MAX14980 is available in a small 42-pin, 3.5mm x 9mm, 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.
