Overview
The SN75LVPE3101RGET is a dual-channel PCI Express 3.0 linear redriver manufactured by Texas Instruments. Designed for signal integrity enhancement, it supports data rates up to 8 Gbps across two independent channels. The device operates on a single 3.3 V power supply with a maximum voltage of 3.6 V and a minimum of 3 V. It features a propagation delay of 150 ps and functions within an operating temperature range of -40°C to +85°C. The component is housed in a VQFN-24 surface-mount package and is supplied in cut tape or reel formats.
Feature Summary
- Dual-channel architecture providing independent signal conditioning for high-speed serial links
- Linear equalization technology optimized for PCI Express 3.0 compliance and signal restoration
- Low-power design utilizing a single 3.3 V supply to minimize energy consumption in host systems
Applications
- PCI Express 3.0 interconnects requiring signal regeneration over lossy traces
- SATA Express interface implementations needing channel extension
- High-speed peripheral connectivity boards demanding low-latency signal buffering
Procurement Notes
Verify the specific ordering suffix RGET to confirm the VQFN-24 package and reel/cut-tape delivery format. Ensure compatibility with 3.3 V logic levels and check that the thermal performance meets the -40°C to +85°C industrial grade requirements for the target environment. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit components.
Selection Notes
Select this component when designing for PCI Express 3.0 speeds up to 8 Gbps where dual-channel linear redriving is required. It is suitable for applications needing low propagation delay and operation from a standard 3.3 V rail. Consider the VQFN-24 footprint constraints and ensure the PCB layout supports the specified thermal dissipation for the industrial temperature range.
Part Context
This device belongs to Texas Instruments' family of high-speed interface signal buffers and repeaters. It complements other redriver solutions like the SN75LVPE801 for SATA applications. The SN75LVPE3101 series focuses specifically on extending reach and maintaining signal quality for PCIe standards without the complexity of full retiming circuits.
Replacement Considerations
Direct substitutes are not explicitly listed in the provided source material. Engineers should evaluate other dual-channel PCIe 3.0 redrivers from Texas Instruments or third-party vendors, ensuring matching pinouts, voltage ranges, and data rate capabilities.
