Overview
The SN65LVPE501RGER, produced by Texas Instruments, is a dual-channel, single-lane PCI Express (PCIe) Gen II redriver and signal conditioner. This device is designed to support data rates of up to 5.0 Gbps and complies with the PCIe specification revision 2.1. It is engineered to minimize signal degradation effects such as crosstalk and inter-symbol interference (ISI), thereby extending the interconnect distance between devices. The SN65LVPE501RGER operates from a single 3.3V supply and features programmable equalization, de-emphasis, and output amplitude control to ensure robust signal integrity in various applications.

Q & A
- What is the primary function of the SN65LVPE501RGER?
The SN65LVPE501RGER is a dual-channel, single-lane PCIe Gen II redriver and signal conditioner designed to support data rates up to 5.0 Gbps.
- What are the supported PCIe speeds for this device?
The device supports both PCIe Gen I (2.5 Gbps) and Gen II (5.0 Gbps) speeds.
- What is the operating voltage range for the SN65LVPE501RGER?
The operating voltage range is 3.0 to 3.6 volts.
- What kind of ESD protection does the SN65LVPE501RGER offer?
The device offers ESD protection with HBM: 3000 V, CDM: 1500 V, and MM: 200 V.
- What are the typical power consumption modes of the SN65LVPE501RGER?
The device has typical power consumption of 330 mW in active mode, 5 mW in auto-low power mode, and less than 1 mW in sleep mode.
- Does the SN65LVPE501RGER support electrical idle and beacon signals?
- What is the package type of the SN65LVPE501RGER?
The device comes in a 24-pin RGE (QFN) package.
- What are some common applications for the SN65LVPE501RGER?
- How does the SN65LVPE501RGER handle receiver detection?
The device performs receiver detection (Rx.Detect) on both channels indefinitely until remote termination is detected, and this feature can be disabled by driving the EN_RXD pin low.
- What is the purpose of the sleep (shut-down) mode in the SN65LVPE501RGER?
The sleep mode is a low power state triggered by setting the RST pin low, reducing device power to less than 1 mW.
