SN75LVCP412RTJT

Overview

The SN75LVCP412RTJT is a dual-channel SATA redriver manufactured by Texas Instruments, designed to extend the reach of Serial ATA connections. It operates at data rates up to 3 Gbps and supports SATA Gen 1 and Gen 2 specifications. The device functions as a signal conditioner for host-to-eSATA connector interconnects, utilizing a single 3.3-V power supply. It features an automatic low-power mode that activates after link idle periods exceeding 10 microseconds, reducing power consumption to less than 20 mW. The component is housed in a 20-pin QFN package (RTJ) suitable for surface-mount installation.

Feature Summary

• Automatic low-power mode activation during link idle periods to conserve energy
• High electrostatic discharge protection meeting IEC61000-4-2 standards
• Support for SATA Gen 1 and Gen 2 data rate specifications

Applications

• Mobile computing platforms requiring extended battery life
• eSATA connector interface signal conditioning
• Host-to-drive interconnection distance extension

Procurement Notes

Verify the specific RTJ suffix indicates the 20-pin QFN package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration into production designs.

Selection Notes

Select this component when extending eSATA cable length beyond standard limits while maintaining strict power efficiency constraints. Ensure the design environment accommodates the 3.3-V supply requirement and the thermal characteristics of the QFN-20 package.

Part Context

This part belongs to the SN75LVCP series of high-speed serial interface redrivers. It complements other TI interface products like the SN75LVCP422, targeting notebook and desktop computer applications where signal integrity over copper traces is critical.

Replacement Considerations

Check for pin-compatible alternatives within the same family, such as the SN75LVCP412A, ensuring functional equivalence in low-power behavior and ESD protection levels.
