Procurement Notes
Verify the specific ordering suffix IRNQR against the manufacturer's official datasheet to confirm the package type and tape-and-reel quantity. Ensure the procurement documentation matches the exact part number to avoid substitution errors with similar family members like the TUSB564. Confirm RoHS compliance status through the latest production release notes.
Selection Notes
Select this component when designing systems requiring linear redriver performance for USB 3.1 Gen 2 speeds. Verify that the system power supply remains within the 3 V to 3.6 V operational window. Ensure the PCB layout accommodates the 40-pin WQFN footprint with appropriate thermal relief for the exposed pad. Check compatibility with upstream source drivers and downstream sink receivers for impedance matching.
Part Context
This device belongs to the TUSB1064 series of USB interface integrated circuits. It is designed to extend cable lengths and maintain signal quality in high-speed digital interfaces. The series includes variants tailored for different automotive or industrial qualifications, such as the TUSB1064-Q1. It serves as a critical component for maintaining eye diagram integrity in congested signal paths.
Replacement Considerations
Publicly documented parameter-equivalent substitutes include the TUSB564IRNQR. Verify functional pinout compatibility before replacement. Other generic alternatives may exist but require careful electrical characterization to ensure equivalent signal integrity performance at 10 Gbps.
