NXS0506GUX

Translators, Level Shifters Overview

The NXS0506GUX is a bidirectional dual-supply level translator with integrated auto-direction control, EMI filtering, and ESD protection. Designed for SD 3.0-compatible memory card interfaces, it bridges host systems operating at 1.1 V to 1.95 V with cards running at 1.7 V to 3.6 V. It supports SDR104, SDR50, DDR50, SDR25, SDR12, High-Speed (50 MHz), and Default-Speed (25 MHz) modes up to 208 MHz clock rates. The component utilizes a 16-terminal XQFN16 package (SOT1161-1) with a 0.4 mm pitch.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'X' corresponds to the required reel packaging configuration before finalizing procurement orders. Confirm that the XQFN16 package variant aligns with the target PCB footprint design constraints. Ensure compatibility with the specified 1.1 V to 1.95 V host supply voltage range during system integration planning.

Translators, Level Shifters Selection Notes

Select this component when interfacing 1.7 V to 3.6 V SD memory cards with low-voltage 1.1 V to 1.95 V hosts requiring SD 3.0 compliance. Choose the XQFN16 package for applications needing a 1.80 x 2.60 mm footprint. Consider the integrated EMI filter and auto-direction features to simplify circuit design and reduce external component count.

Translators, Level Shifters Part Context

The NXS0506 series includes variants such as NXS0506UP in a WLCSP16 package and NXS0506GU in an XQFN16 package. The NXS0506GUX specifically denotes the XQFN16 version. This family addresses the need for high-speed data translation in portable devices while maintaining signal integrity through integrated filtering and protection mechanisms.

Translators, Level Shifters FAQ

How does the device handle data direction?

The NXS0506GUX features an auto-direction sensing circuit that automatically determines if data is being transferred from the memory card to the host or vice versa, removing the need for manual direction control.

What is the function of the CLKFB pin?

The CLKFB pin provides a feedback clock signal on the host side to compensate for propagation delays introduced by the translator and PCB tracks, ensuring timing accuracy for data read-back from the memory card.
