PTN36241G Block Diagram


  • Supports USB 3.0 specification (SuperSpeed only)
  • Compliant to SuperSpeed USB 3.0 standard
  • Support of two channels
  • Pin out data flow matches USB 3.0 Micro-AB/Micro-B receptacle pin assignments
  • Two control pins to select optimized signal conditions
    • Receive equalization on each channel to recover from InterSymbol Interference (ISI) and high-frequency losses, with provision to choose equalization gain settings per channel
    • Transmit de-emphasis on each channel delivers pre-compensation suited to channel conditions
    • Output swing adjustment
  • Integrated termination resistors provide impedance matching on both transmit and receive sides
  • Automatic receiver termination detection
  • Low active power: 189 mW/105 mA (typical) for VDD = 1.8 V
  • Power-saving states:
    • 1.8 mW/1 mA (typical) when in U2/U3 states
    • 0.9 mW/0.5 mA (typical) when no connection detected
    • 3.6 μW/2 μA (typical) when in Deep power-saving state
  • Excellent differential and common return loss performance
    • 14 dB differential and 15 dB common-mode return loss for 10 MHz to 1250 MHz
  • Flow-through pinout to ease PCB layout and minimize crosstalk effects
  • Hot Plug capable
  • Power supply: VDD = 1.8 V (typical)
  • Compliant with JESD 78 Class II
  • Very thin X2QFN12 package: 1.25 mm × 2.1 mm × 0.35 mm, 0.4 mm pitch
  • ESD protection exceeds 7000 V HBM per JDS-001-2012 and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
  • Operating temperature range: -40 °C to 85 °C
  • Smart phones, tablets
  • Active cables
  • Notebook/netbook/nettop platforms
  • Docking stations and AIO platforms
  • USB 3.0 peripherals such as flat panel display, consumer/storage devices, printers or USB 3.0 capable hubs/repeaters
