PI5USB216XUAEX

Signal Buffers, Repeaters, Splitters Overview

The PI5USB216XUAEX is a USB 2.0 High-Speed signal conditioner designed to boost signals and insert pre-emphasis to compensate for inter-symbol interference (ISI) loss in channels before and after the device. It supports data rates up to 480 Mbps with a wide supply voltage range of 2.3V to 5.5V and 5.5V tolerance on USB ports. The component operates within an industrial temperature range of -40°C to +85°C, consumes 22mA typical active current, and features ESD protection rated at 2kV HBM and 1kV CDM. It is housed in a 12-contact X2QFN (XUA) package.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix 'E' confirms lead-free and green status compliant with RoHS directives. Confirm the 'X' suffix indicates tape and reel packaging. Ensure the design accommodates the required 12-contact X2QFN footprint and validates the 2.3V to 5.5V operating voltage against system power rails.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when signal integrity degradation over long channels requires compensation. Verify if pin-based configuration suffices or if I2C programmability is needed for dynamic adjustment. Consider the integrated BC 1.2 controller if host charging functionality is required without additional external circuitry.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI5USB216 family of USB 2.0 signal conditioners manufactured by Diodes Incorporated. It serves as a high-speed repeater specifically optimized for USB 2.0 applications where signal loss occurs due to PCB trace length or cable extensions.

The automotive-compliant variant is available under the separate datasheet for the PI5USB216Q.

Signal Buffers, Repeaters, Splitters FAQ

How is the BOOST/PRE-EMPHASIS level configured?

In pin mode, it is selected via an external pulldown resistor at the BOOST pin. In I2C mode, it is initialized by writing to the corresponding register.

What is the function of the SEN pin?

In pin mode, the SEN pin configures receiver sensitivity levels (High, Medium, Low). After reset, it functions as an output flag indicating High-Speed mode detection.

How is the BC 1.2 CDP controller enabled?

The controller is enabled by pulling the CDP_ENZ pin low. If left open, an internal 500k pull-up resistor keeps the controller disabled.
