Page 9: Chapter 1. Overview
USB3503 Ultra Fast USB 2.0 Hub on an RoHS compliant Printed Circuit Board (PCB). The EVB-USB3503 QFN is designed to demonstrate the unique features of this device using a low-cost PCB implementation with ganged port power control for the three downstream USB 2.0 ports. -
Page 10: Chapter 2. Hardware Configuration
Do not exceed 4 A total current consumption from the + 5 VDC power supply. The EVB-USB3503 QFN must be connected to an HSIC upstream host via the DATA (J5) and STROBE (J4) connectors using the provided U.FL coaxial cables. When removing these cables from the EVB for any reason, the provided HSIC Extraction tool must be used. -
Page 11: Usb3503 Configuration
2.1.2 USB3503 Configuration Default: I C configuration is bypassed by default on the EVB-USB3503 QFN evalua- tion board. The hub will use the internal default configuration and automatically transi- tion to the hub communication stage when it is powered on. -

EVB-USB3503 QFN Evaluation Board User’s Guide FIGURE 2-2: HUB_CONNECT SWITCH POSITIONS 2.1.3 Clock Source – 26 MHz Oscillator By default, a 26 MHz oscillator (Y1) is populated on the evaluation board as the clock source for the USB3503. The REFSEL[1:0] pins are used to select the frequency of the clock. -
Page 13: Power Source - Self-Powered
2.1.4 Power Source – Self-Powered The EVB-USB3503 QFN only supports self-powered operation and is powered by one +5 VDC regulated external power supply. The +5 VDC, 4 A power supply plugs into the board via a 2.1 mm connector (J3). The external power supply controls the on board +3.3 VDC voltage regulator and on board +1.8 VDC voltage regulator. -
