SN75LVPE802RTJR

Overview

The SN75LVPE802RTJR is a dual-channel SATA Express signal conditioner manufactured by Texas Instruments. It supports data rates up to 8 Gbps and operates from a single 3.3-V supply. The device integrates selectable equalization and de-emphasis capabilities, along with an integrated output squelch function. It features hot-plug capability and out-of-band (OOB) detection. The component is housed in a 20-pin QFN package measuring 4 mm x 4 mm. Typical power consumption is less than 220 mW, with lower consumption in auto low-power and standby modes.

Feature Summary

• Supports SATA Express specifications including SATA Gen 1, 2, and 3, as well as PCIe 1, 2, and 3 standards.
• Provides selectable equalization and de-emphasis settings to compensate for interconnect losses in FR4 trace materials.
• Incorporates an out-of-band detector that automatically squelches the output when input differential voltage falls below a threshold.
• Handles spread spectrum clocking transmission per SATA standard and supports hot-plug operations.

Applications

• SATA Express signal conditioning
• PCIe link extension
• High-speed serial interconnect compensation

Procurement Notes

Verify the specific suffix RTJR against the manufacturer datasheet to confirm the reel packaging quantity and tape-and-reel specifications. Ensure the order matches the exact part number variant required for the intended PCB layout and assembly process. Cross-reference the RoHS compliance status and humidity sensitivity level before procurement.

Selection Notes

Select this component for applications requiring dual-channel signal regeneration at speeds up to 8 Gbps. It is suitable for designs needing integrated equalization without external components. Consider the 3.3 V supply requirement and the 20-pin QFN package dimensions during the schematic capture and footprint design phases.

Part Context

This part belongs to the SN75LVPE802 series of SATA Express equalizers and redrivers. It is designed to extend the reach of high-speed serial links by compensating for channel loss. The device complements other interface buffers and repeaters in storage and expansion card architectures.
