SN65LVPE501RGER

Overview

The SN65LVPE501RGER is a dual-channel linear redriver and signal conditioner manufactured by Texas Instruments. It supports data rates up to 5 Gbps, making it suitable for PCI Express Gen II applications. The device operates on a single 3 V to 3.6 V power supply with a typical operating current of 120 mA. It features input equalization and output de-emphasis to extend interconnect distances. The component is housed in a 24-pin VQFN package (4x4 mm) and supports CML or LVCMOS inputs with CML outputs. Propagation delay is specified at 280 ps, and the operational temperature range spans from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent signal conditioning for two lanes
• Programmable equalization and de-emphasis capabilities to compensate for channel loss
• Supports low-power modes including sleep and standby states for energy efficiency
• Compatible with standard CML and LVCMOS logic families for flexible integration

Applications

• PCI Express Gen II link extension
• High-speed digital interconnect systems
• Signal integrity improvement in PCB traces

Procurement Notes

Verify the specific suffix 'RGER' against the manufacturer's official datasheet to confirm tape-and-reel packaging and lead-free status. Ensure the order quantity aligns with the factory reel size requirements. Confirm moisture sensitivity level handling procedures are followed upon receipt to maintain component reliability during assembly.

Selection Notes

Select this component when extending PCI Express Gen II links requiring dual-lane support. Compare propagation delay and power consumption against alternative redrivers if system latency or thermal constraints are critical. Verify that the 24-VQFN footprint matches the design layout and that the 3V-3.6V supply voltage aligns with the target platform.

Part Context

This part belongs to the SN65LVPE501 series of high-speed linear redrivers. It is functionally related to the SN65LVPE501RGET variant, differing primarily in packaging configuration. The series is designed to address signal degradation in high-speed serial interfaces, serving as a bridge between transmitters and receivers over lossy channels.
