Product details

Signal integrity budget for 6 Gbps serial links

The MAX4951CTP+ is a single-channel eSATA buffer and re-driver that reconditions the signal at the cable midpoint or receiver end, compensating for PCB trace and connector losses that would otherwise close the eye at 6 Gbps. Rated for a maximum data rate of 6 Gbps, it meets the eSATA 3.0 physical-layer requirement and provides enough margin for the 1.5 Gbps and 3 Gbps backward-compatible modes. The 240 ps typical propagation delay sets the timing budget for the link — the total round-trip latency through the re-driver plus the cable delay must stay within the SATA link-layer timeout window.

ROHS3 compliant per the manufacturer's declaration, with no exemptions listed — suitable for EU RoHS and similar global restricted-substance regulations.

Frequently asked questions

What is the MAX4951CTP+ used for?

It is a single-channel eSATA buffer and re-driver that restores signal integrity on serial links running at up to 6 Gbps, typically placed at the cable midpoint or near the receiver to compensate for PCB and connector losses.

What package does the MAX4951CTP+ come in?

The tube packaging is the standard delivery format.

What compliance documentation does Analog Devices provide for MAX4951CTP+?

Analog Devices declares the MAX4951CTP+ as ROHS3 compliant with no exemptions. Standard compliance documentation includes the RoHS certificate of compliance and material declaration; REACH and conflict-minerals reports are available on request.
