MAX4952B
Dual 1.5/3.0/6.0Gbps SAS/SATA Redriver
Low-Cost MAX4952B Routes and Redrives the Signal Through Connectors
|
Status
Active: In Production.
Description
The MAX4952B dual-channel redriver is designed to redrive one full lane of SAS or SATA signals up to 6.0Gbps and operates from a single +3.3V supply. The MAX4952B is designed for commercial SAS or SAS/SATA applications, such as servers.
The MAX4952B features independent output boost and enhances signal integrity at the receiver by re-establishing full output levels. SAS/SATA out-of-band (OOB) signaling is supported using high-speed amplitude detection on the inputs and squelch on the corresponding outputs.
Inputs and outputs are all terminated in 50Ω internally and exhibit excellent return loss.
The MAX4952B is available in a small, 20-pin, 4.0mm × 4.0mm TQFN package with flow-through traces for ease of layout. This device is specified over the 0°C to +70°C operating temperature range.
