Overview
The SN75LVCP412CDRTJT is a dual-channel SATA 3 Gbps redriver and signal conditioner manufactured by Texas Instruments. Designed for surface-mount installation in a QFN package, it operates on a single 3.3 V supply with a maximum current consumption of 55 mA. The device supports data rates up to 3 Gbps and functions within an ambient temperature range of 0°C to +85°C. It integrates automatic low-power mode capabilities to reduce energy usage during link idle periods, making it suitable for mobile computing platforms where power efficiency is critical.
Feature Summary
- Integrates automatic low-power mode that activates after 10 microseconds of link inactivity to conserve battery life in mobile applications
- Provides enhanced electrostatic discharge protection compliant with IEC61000-4-2 standards for reliable eSATA connectivity
- Functions as a dual-channel signal conditioner to extend interconnect distances between host systems and external storage
Applications
- Mobile computing platforms requiring extended battery life
- eSATA connector interfaces for external storage devices
- Notebook and desktop computer expansion solutions
Procurement Notes
Verify the specific suffix RTJT against the manufacturer datasheet to confirm the exact reel quantity and tape specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm the operating temperature range aligns with your system's thermal design constraints before finalizing procurement orders.
Selection Notes
Select this component when designing SATA links requiring signal regeneration over longer traces or cables. Compare its 55 mA supply current against other LVCP series variants to optimize power budgets. Verify that the QFN package footprint matches your PCB layout constraints and that the 3.3 V logic levels are compatible with your host controller interface.
Part Context
This part belongs to the SN75LVCP4xx series of ultra-low power SATA redrivers from Texas Instruments. It complements the broader portfolio of high-speed interface solutions designed for mobile and computing applications. The device addresses signal integrity challenges in Serial ATA environments while prioritizing power efficiency for portable electronics.
Replacement Considerations
The SN75LVCP412A serves as the primary functional equivalent within the same product family. Verify pinout compatibility and electrical parameters against the official datasheet before substitution.
