Overview
The SN75LVCP412ARTJR is a dual-channel SATA 3 Gbps redriver and signal conditioner manufactured by Texas Instruments. It operates from a single 3.3 V supply with a typical current consumption of 55 mA. The device supports data rates up to 3 Gbps and features an automatic low-power mode that reduces power dissipation to less than 20 mW during link idle periods exceeding 10 microseconds. It is housed in a 20-pin QFN package (RTJR) rated for commercial temperatures from 0°C to +85°C. The component includes high ESD protection, certified to IEC61000-4-2 standards with 8 kV contact discharge and 15 kV air discharge tolerance.
Feature Summary
- Ultra-low power operation with automatic low-power mode activation during link idle states
- High electrostatic discharge (ESD) protection capability for eSATA connector environments
- Dual-channel architecture designed for SATA host and eSATA interconnect extension
Applications
- Mobile computing platforms requiring extended battery life
- eSATA external storage connectivity solutions
- Desktop computer expansion cards and workstations
Procurement Notes
Verify the specific RTJR suffix corresponds to the 20-pin QFN package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified commercial temperature range of 0°C to +85°C for the target application environment.
Selection Notes
Select this component for applications requiring signal regeneration over SATA interconnects where power efficiency is critical. The automatic low-power mode distinguishes it from standard redrivers by actively conserving energy during inactive periods. Verify that the 3 Gbps data rate specification meets the system's bandwidth requirements without necessitating higher-speed alternatives.
Part Context
This device belongs to the SN75LVCP4xx series of low-voltage CMOS signal conditioners. It complements other members like the SN75LVCP412 and SN75LVCP422 within Texas Instruments' interface portfolio. The series targets mobile and general-purpose computing applications needing reliable SATA signal integrity with minimal power impact.
Replacement Considerations
The SN75LVCP412A serves as the primary functional equivalent within the same product family. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement part supports the required 3 Gbps data rate and low-power operational modes.
