SN75LVPE802RTJT

Overview

The SN75LVPE802RTJT is a dual-channel SATA Express equalizer and redriver manufactured by Texas Instruments. It supports data rates up to 8 Gbps, compatible with SATA Gen 1/2/3 (1.5/3/6 Gbps) and PCIe Gen 1/2/3 (2.5/5/8 Gbps). The device operates from a single 3.3 V supply with an input voltage range of 3 V to 3.6 V. Typical operating current is 80 mA, resulting in power dissipation under 220 mW. It features selectable equalization and de-emphasis settings to compensate for interconnect losses. The component is housed in a 20-pin QFN package measuring 4 mm x 4 mm.

Feature Summary

• Supports SATA Express specifications including hot plug capability and out-of-band detection
• Provides selectable equalization and de-emphasis to compensate for channel loss
• Integrated output squelch maintains stable common-mode voltage during low input conditions
• Handles spread spectrum clocking transmission per SATA standards

Applications

• SATA Express signal conditioning
• PCIe signal integrity enhancement
• High-speed serial link redriving

Procurement Notes

Verify the specific RTJT suffix against the manufacturer's datasheet to confirm the tape and reel packaging configuration. Ensure the order matches the exact part number to avoid discrepancies in shipping format or moisture sensitivity level handling requirements.

Selection Notes

Select this component when designing systems requiring support for both SATA and PCIe signals at speeds up to 8 Gbps. The integrated equalization simplifies board layout by compensating for FR4 trace losses without external components. Verify that the system environment remains within the extended commercial temperature range of 0°C to 85°C.

Part Context

This part belongs to the SN75LVPE802 series of signal conditioners. The RTJT suffix indicates a specific packaging variant, typically a 20-lead QFN with a 4x4 mm body size. It is designed as a versatile solution for maintaining signal integrity in high-speed storage and expansion interfaces.

Replacement Considerations

Direct substitutes include other Texas Instruments SATA Express equalizers such as the SN75LVPE801DRFT. Verify pin compatibility and electrical parameters before substitution.
