Overview
The SN75LVCP412CDRTJR is a dual-channel SATA Express redriver manufactured by Texas Instruments. It operates on a single 3.3 V supply with a maximum current consumption of 80 mA. The device supports data rates up to 3 Gbps and functions within an operating temperature range of 0°C to +85°C. Packaged in a 20-pin QFN (RTJ) format, it integrates automatic low-power mode capabilities to reduce energy usage during link idle periods.
Feature Summary
- Integrates automatic low-power mode that activates after 10 microseconds of link inactivity to conserve energy
- Provides high electrostatic discharge protection for eSATA connectors through IEC61000-4-2 level certification
- Designed to extend interconnect distances between SATA hosts and eSATA connectors
Applications
- Mobile computing platforms requiring extended battery life
- Desktop computer internal and external storage connections
- Workstation and server SATA expansion interfaces
Procurement Notes
Verify the specific suffix RTJR against the manufacturer datasheet to confirm reel packaging specifications. Ensure compatibility with the required 20-QFN footprint and thermal dissipation requirements. Confirm RoHS compliance status directly from the official documentation before integration into production designs.
Selection Notes
Select this component when designing systems requiring signal regeneration for SATA links exceeding standard trace lengths. The integrated low-power feature makes it suitable for battery-operated devices where power efficiency is critical during idle states compared to standard linear repeaters.
Part Context
This part belongs to the SN75LVCP4xx series of ultra-low power SATA redrivers. It complements other members like the SN75LVCP412 and SN75LVCP422, offering a specialized solution for mobile and desktop applications needing reliable signal integrity over extended copper interconnects.
Replacement Considerations
Direct substitutes include the SN75LVCP412 and SN75LVCP412A. Verify pinout compatibility and electrical characteristics against the original design requirements before swapping components.
