Diodes Incorporated PI5USB216Q2XUAEX

Overview

PI5USB216Q2XUAEX from Diodes Incorporated is an AEC-Q100 Grade 2 automotive-qualified USB 2.0 high-speed signal conditioner with symmetrical boost/pre-emphasis (4 settings), programmable receiver sensitivity (3 levels), integrated BC 1.2 CDP controller, and dual-mode configuration (pin or I²C). It compensates ISI loss in channels up to 5 m (or 10 m with cascaded units) and supports host/device-agnostic USB PHY extension in infotainment head units and active cables.

For engineers reviewing the PI5USB216Q2XUAEX datasheet, PI5USB216Q2XUAEX pinout, PI5USB216Q2XUAEX application, or PI5USB216Q2XUAEX equivalent, key selection factors include its 480.24 Mbps HS bit rate, 100 ps rise/fall time, 2.3–5.5 V supply range, AEC-Q100 qualification, and dual-mode configurability for robust USB signal integrity in automotive environments.

Technical Context

The PI5USB216Q operates as a transparent, non-inverting analog signal conditioner for USB 2.0 high-speed differential pairs only - it leaves LS/FS/OTG/BC signals unaltered. Its patented symmetrical D+/D− boost/pre-emphasis architecture maintains stable common-mode voltage while compensating both pre- and post-conditioner channel losses.

Configuration is supported in two mutually exclusive modes: pin-strapped (using BOOST, SEN/HS, SCL/CD, RSTN) or I²C (7-bit address 0x2C, 1 MHz max). Device attach (CD) and HS handshake success (HS) are actively detected and reported; BC 1.2 CDP functionality is enabled via CDP_ENZ low assertion.

Key Specifications

Pinout & Package

FAQ

What is the function of the SEN/HS pin?

The SEN/HS pin serves dual roles: during power-on reset, it acts as a 3-level input (VCC/floating/GND) to set receiver sensitivity level; after reset, it becomes an open-drain output asserting the HS flag upon successful high-speed handshake detection. This eliminates need for external GPIO monitoring of USB link state.

Can PI5USB216Q2XUAEX operate in both host and device configurations?

Yes - the PI5USB216Q2XUAEX is host/device agnostic. It conditionally processes only USB 2.0 high-speed differential signals regardless of direction, with no internal protocol awareness or role-dependent logic. It functions identically whether placed between host PHY and connector or device PHY and connector.

How does the BOOST pin configure pre-emphasis levels?

The BOOST pin accepts four external pull-down resistor values (0 Ω, ~1.8 kΩ, ~3.6 kΩ, >7.5 kΩ) to select corresponding boost/pre-emphasis strength. The setting is latched once at RSTN de-assertion and cannot be changed dynamically - ensuring deterministic analog behavior without runtime configuration overhead.

Is I²C communication required to use PI5USB216Q2XUAEX?

No - I²C is optional. The device defaults to pin-mode configuration if SDA and SCL/CD are not pulled high during power-up. Pin mode uses BOOST, SEN/HS, and CDP_ENZ for static setup, eliminating I²C bus dependency and simplifying designs where dynamic reconfiguration is unnecessary.
