Overview
The SN65LVPE502ARGER is a dual-channel USB 3.0 redriver and equalizer manufactured by Texas Instruments, designed to extend interconnect distances in high-speed serial links. It supports SuperSpeed data rates up to 5 Gbps and complies with the USB 3.0 specification revision 1.0. The device features programmable equalization, de-emphasis, and amplitude swing controls to optimize signal integrity across PCB traces or cables. It operates within a supply voltage range of 3 V to 3.6 V and draws a typical operating current of 120 mA. The component is housed in a 24-pin VQFN package suitable for surface mount applications.
Feature Summary
- Supports electrical idle conditions and low-frequency periodic signals (LFPS) required for USB 3.0 power management modes.
- Provides programmable signal conditioning including equalization, de-emphasis, and amplitude swing adjustment.
- Includes dedicated low-power modes such as sleep mode and low-power state when unplugged.
- Capable of functioning in USB compliance mode to verify transmitter adherence to voltage and timing specifications.
Applications
- Extending cable lengths between USB hosts and peripheral devices.
- Signal conditioning on high-density motherboard interconnects.
- USB 3.0 compliance testing setups for transmitter verification.
Procurement Notes
Verify the specific suffix 'ARGER' against the manufacturer's official datasheet to confirm pinout and packaging details. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for obsolescence notices as this family may have replacement recommendations from Texas Instruments.
Selection Notes
Select this component for designs requiring active signal regeneration for USB 3.0 SuperSpeed links. Ensure the design accommodates the 3 V to 3.6 V supply requirement and the thermal characteristics of the VQFN-24 package. Consider the programmable settings if trace loss compensation is necessary for the specific PCB stack-up.
Part Context
This part belongs to the SN65LVPE502CP series of dual-channel USB 3.0 redrivers. It serves as a signal conditioner to mitigate attenuation in high-speed differential pairs. Similar devices in the family include the SN65LVPE502A and SN65LVPE502CPRGER, which share functional capabilities but may differ in packaging or temperature ratings.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Texas Instruments for current recommended replacements if this component is marked as Not Recommended for New Designs (NRND).
