TUSB211ARWBRQ1

Overview

The TUSB211ARWBRQ1 is an automotive-grade USB 2.0 high-speed signal conditioner designed to compensate for AC and DC transmission channel losses. It supports data rates up to 480 Mbps with a supply voltage range of 2.3 V to 6.5 V. The device operates within a temperature range of -40°C to 105°C and features four selectable equalization levels configured via external pull-down resistors on the EQ pin. It utilizes a 12-pin X2QFN package measuring 1.6 mm by 1.6 mm.

Feature Summary

• Compensates for inter-symbol interference and signal loss in high-speed channels using edge boost and DC boost functions.
• Maintains signal integrity without altering packet timing or adding propagation delay.
• Supports daisy-chaining of multiple devices to extend cable length capabilities beyond standard limits.

Applications

• Automotive infotainment systems
• Active cables and cable extenders
• Backplane connections

Procurement Notes

Verify the specific ordering suffix to confirm the packaging quantity, as the RWB package is available in both large tape-and-reel (3000 units) and small tape-and-reel (250 units) configurations. Ensure the selected variant matches the required production volume and handling specifications for the assembly line.

Selection Notes

Select this component when operating in automotive environments requiring AEC-Q100 qualification and extended temperature ranges. Compare against the commercial TUSB211A if industrial grade performance is sufficient, noting that the Q1 variant supports a wider supply voltage range up to 6.5 V compared to the 3.3 V limit of some pin-compatible counterparts.

Part Context

This part belongs to the TUSB211A-Q1 family of USB 2.0 high-speed signal conditioners. It is pin-compatible with other members of the series, including the TUSB211, TUSB212, TUSB214, TUSB216, and TUSB217A, facilitating design upgrades or replacements within existing hardware architectures.

Replacement Considerations

The TUSB211QRWBRQ1 is a confirmed substitute within the same product family. Both parts share identical pinouts and functional characteristics, differing primarily in their operational status and availability timelines.

FAQ

How is the equalization level determined?

The equalization level is set by the value of the external pull-down resistor connected to the EQ pin. The setting is latched at power-up and cannot be changed dynamically during operation.

Does the device affect low-speed or full-speed signals?

No, the TUSB211ARWBRQ1 uses a patented design that leaves low-speed and full-speed signal characteristics unaffected while providing compensation only for high-speed signals.

What is the maximum number of devices that can be daisy-chained?

Up to four TUSB211A-Q1 devices can be daisy-chained to support high-loss applications and extend the effective cable length.
