MAX4951CTP+

The MAX4951CTP+ is a SATA I/SATA II bidirectional re-driver in 20 pin TQFN package. The dual-channel buffer is designed to re-drive serial-ATA (SATA) I and SATA II signals and is functional up to 6.0Gbps for next-generation data rates. The MAX4951 can be placed near an eSATA connector to overcome board losses and produce an eSATA-compatible signal level. The MAX4951 preserves signal integrity at the receiver by re-establishing full output levels and can reduce the total system jitter (TJ) by squaring up the signal. This device features channel-independent digital boost controls to drive SATA outputs over longer trace lengths or to meet eSATA specifications. SATA Out of Band (OOB) signalling is supported using high-speed amplitude detection on the inputs and squelch on the corresponding outputs. Inputs and outputs are all internally 50 ohm terminated and must be AC-coupled to the SATA controller IC and SATA device.
