NXP Semiconductors PTN3222 1-Port eUSB2 to USB2 Redrivers

NXP Semiconductors PTN3222 1-Port eUSB2 to USB2 Redrivers are designed to perform translations between eUSB2 and USB2 signaling schemes. These robust devices are used in systems that have a eUSB2 interface on one side and a USB2 interface on the other side. NXP Semiconductors PTN3222 1-Port eUSB2 to USB2 Redrivers support a host repeater, device repeater, or dual role repeater function.

Features

  • 1-port eUSB2 to USB2 redriver functionality
  • Conforms to USB2 specification along with relevant ECNs
  • Conforms to eUSB2 specification v1.1
  • Supports host-only repeater, device-only repeater, and dual-mode repeater role
  • Supports all USB2.0 data rates
    • Low-speed operation (1.5Mbps)
    • Full-speed operation (12Mbps)
    • High-speed operation (480Mbps)
  • Supports RAP accesses for a select set of register accesses
  • Integrated and selectable pullup and pulldown resistors on both eUSB2 and USB2 ends
  • Signal Integrity (SI) configurability
    • eUSB2 – Tx de-emphasis, Rx equalization, Rx squelch threshold, Tx output swing
    • USB2 – HS disconnect detection threshold, Rx squelch threshold, Rx termination, Rx equalization, Tx de-emphasis, Tx slew rate, Tx output swing
  • Supports BC1.2 power provider CDP configuration capability in host mode
  • Low current consumption
    • Supports eUSB2 and USB2 power management
    • Implements Deep standby mode for lowest power consumption
  • Robustness features

    • USB2 data pins withstand short to GND for 24 hours
    • USB2 data pins withstand collision on DP/DN pins due to faulty USB devices
  • GPIOs and high-speed data pins are back power safe
  • I2C target interface supports standard mode, fast mode, and fast mode plus
  • Power supplies - VDD3V3, VDD1V8
  • ESD HBM 2kV CDM 500V
  • Operating ambient temperature range -40°C to +85°C
  • Available in WLCSP12 and QFN12 package

Applications

  • eUSB2 to USB2 repeater function in platforms (e.g., hosts, devices, hubs, routers, protocol bridges, etc.) with Standard A/ Standard B/ Micro-B/USB Type-C connector scenarios
  • Host-only repeater
  • Device only repeater
  • Dual role repeater (as determined dynamically in the application)
