MAX4952B

19-5126; Rev 0; 1/10 www.DataSheet4U.com TION KIT EVALUA BLE IL AVA A Dual 1.5/3.0/6.0Gbps SAS/SATA Redriver MAX4952B General 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 and SATA out-of-band (OOB) signaling are supported using high-speed amplitude detection on the inputs and squelch on the corresponding outputs. Inputs and outputs are all terminated in 50I internally and exhibit excellent return loss. The MAX4952B is available in a small, 20-pin, 4.0mm x 4.0mm TQFN package with flow-through traces for ease of layout. This device is specified over the 0NC to +70NC operating temperature range.
