MAX4951CTP+T

Signal Buffers, Repeaters, Splitters Overview

The MAX4951CTP+T is a dual-channel bidirectional re-driver designed for serial-ATA (SATA) I and SATA II signals, supporting data rates up to 6.0Gbps. It operates from a single +3.3V supply with typical operating current of 90mA and standby current of 7mA. The device features internal 50Ω input/output termination resistors and channel-independent digital boost controls. Key electrical parameters include a propagation delay of 240ps, output rise/fall time of 60ps, and ESD protection rated at ±5.5kV via the Human Body Model. It functions within an operating temperature range of 0°C to +70°C.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify that the component matches the exact part number MAX4951CTP+T, including the lead-free suffix. Confirm the package type is 20-pin TQFN with an exposed pad. Ensure the supplier provides documentation confirming compliance with RoHS standards and the specified 0°C to +70°C operating temperature range before finalizing procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when signal integrity degradation due to board losses requires re-driving SATA signals near connectors. It is suitable for designs needing independent channel boosting to accommodate longer trace lengths or specific eSATA requirements. Ensure the design accommodates the required AC coupling capacitors and proper power-supply decoupling near the VCC pins.
