Overview
The SN75LVCP422DB is a two-channel SATA redriver manufactured by Texas Instruments, designed to restore signal integrity for high-speed serial data. It supports data rates up to 3 Gbps and operates from a single 3V to 3.6V power supply. The device draws a typical supply current of 55mA and functions within an operating temperature range of 0°C to 85°C. Housed in a 20-lead SSOP package with a width of 5.30mm, it serves as a buffer and line driver for eSATA applications. The component is currently active and available in tape-and-reel packaging.
Feature Summary
- Provides signal conditioning for two independent channels to compensate for trace loss
- Supports hot-plug capable connections with receiver detect functionality
- Integrates output squelch to maintain stable common-mode voltage during idle states
Applications
- eSATA host and device interfaces
- SATA Gen 1 and Gen 2 link extensions
- PCB trace loss compensation in storage systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and temperature grade. Confirm that the 20-SSOP footprint matches the target PCB design. Check for any recent lifecycle status changes or alternative package options before finalizing procurement plans.
Selection Notes
Select this component when designing for SATA speeds up to 3 Gbps requiring differential signal regeneration. Ensure the system voltage aligns with the 3V to 3.6V operational range. Consider the 20-SSOP package constraints for board space and thermal management requirements relative to the 55mA supply current.
Part Context
This part belongs to the SN75LVCP4xx series of SATA redrivers from Texas Instruments. It shares functional similarities with the SN75LVCP412 but is optimized specifically for 3 Gbps operation. It complements other interface ICs like the SN75LVPE802, which targets higher 8 Gbps speeds for SATA Express applications.
Replacement Considerations
The SN75LVCP422D (non-BR suffix) is a direct equivalent with identical electrical specifications but may differ in packaging quantity. Verify pin compatibility if substituting with family members like the SN75LVCP412.
