Overview
The SN75LVCP412ARTJT is a dual-channel SATA 3 Gbps redriver and signal conditioner manufactured by Texas Instruments. It operates from a single 3.3V supply with a typical current consumption of 55mA. The device supports data rates up to 3Gbps and features an automatic low-power mode that activates after link idle periods exceeding 10 microseconds, reducing power consumption to less than 20mW. It is housed in a 20-pin RTJ QFN package (4mm x 4mm) and is rated for operation within a commercial temperature range of 0°C to 85°C.
Feature Summary
- Integrates automatic low-power mode to extend battery life in mobile platforms during link idle states
- Provides high electrostatic discharge protection on high-speed pins compliant with IEC61000-4-2 standards
- Supports SATA Gen 1 and Gen 2 specifications for reliable signal regeneration
Applications
- Mobile computing platforms requiring extended battery endurance
- eSATA connector interconnects for external storage devices
- Server and workstation internal SATA channel extension
Procurement Notes
Verify the specific suffix ARTJT corresponds to the 20-pin RTJ QFN package configuration. Confirm the manufacturer source is Texas Instruments or an authorized distributor. Ensure the component status is listed as active or recommended for new designs. Check for RoHS compliance documentation if required for the target assembly process.
Selection Notes
Select this component when designing systems requiring SATA 3Gbps signal integrity over PCB traces. The integrated low-power mode makes it suitable for portable devices where energy efficiency is critical. Compare against the SN75LVCP422 if higher data rate support is not required but similar functionality is needed. Ensure the design accommodates the 3.3V supply voltage and thermal requirements for the QFN package.
Part Context
This part belongs to the SN75LVCP4xx series of high-speed signal conditioners designed for SATA applications. It complements other members like the SN75LVCP412 and SN75LVCP422, offering a balance of performance and power efficiency. The series addresses the need for signal regeneration in modern computing architectures connecting host controllers to storage drives.
Replacement Considerations
The SN75LVCP412A is a related variant within the same product family. Verify pinout compatibility and electrical specifications before substitution. Other members of the LVCP4xx series may offer different packaging or feature sets.
