Reduced BOM Schematic for CYUSB332x family of HX3 USB 3.0 HUB Controller

Last Updated: 
Oct 17, 2014

The CYUSB332x family is designed to support two advanced featured of the HX3 USB 3.0 HUB, ACA-Dock and SharedLink.

ACA-Dock : Supported in CYUSB3324-88LTXC and CYUSB3328-88LTXC parts

SharedLink : Supported in CYUSB3328-88LTXC and CYUSB3328-88LTXC parts

  1. Reduced BOM Schematic for CYUSB3328-88LTXC :

    This Schematic replicates the complete functionality of CY4613 DVK , except for certain optional features such as External EEPROM, Optional Port Status Indicator LEDs, Overvoltage Protection IC, Reset Button and Mode Select Jumper Blocks and and Diodes for additional ESD/EMI protection.

    The features supported by this design are:

    • 2 Downstream (DS) USB 3.0 ports, 2 DS SuperSpeed ports, 2 DS USB 2.0 (Shared link on 2 DS ports)
    • Supports Battery Charging v1.2 on USB 3.0 and USB 2.0 ports
    • Supports Ghost Charging™ on USB 3.0 and USB 2.0 ports
    • Supports individual DS port power control - supplies current up to 2.1A per Downstream port
    • ACA-Dock feature
  2. Reduced BOM Schematic for CYUSB3324-88LTXC:

    This Schematic implemented the ACA-Dock functionality but not the ShardLink feature of HX3. This design excludes optional features such as External EEPROM, Optional Port Status Indicator LEDs, Overvoltage Protection IC, Reset Button and Mode Select Jumper Blocks and and Diodes for additional ESD/EMI protection.

    The features supported by this design are:

    • 4 Downstream (DS) USB 3.0 ports
    • Supports Battery Charging v1.2 on all Downstream ports
    • Supports Ghost Charging™
    • Supports individual DS port power control - supplies current up to 2.1A per Downstream port
    • ACA-Dock feature

Both Reduced BOM designs continue to support HX3 configuration through the Blaster Plus utility , when used with either an external EEPROM or an I2C Master.
