Description

PI3AUX221 is an interface chip between the discrete Graphics Processing Unit (GPU) and the Display Port (DP) connector. The device is ideal for applications that require support of Dual-Mode Display Port. It integrates the support function for Display Data Channel (DDC) in HDMI mode and includes the functions of level translation, mux function, over-voltage protection, backdrive protection and inversion of Hot Plug Detect (HPD). The level translation function allows a wide range of voltage between 1V to 5V. The device eliminates the requirement of many discrete components, and it is available in a space-saving 12-pin ultrathin 0.65mm high 2x2 mm QFN package.

Feature(s)

  • AC-coupling of AUX signal or DC-level translated Display Data Channel (DDC) signal controlled by the SEL pin
  • Bi-directional level translation of 100KHz DDC signals
  • Inverted level translation of HPD signal from DisplayPort Connector to GPU
  • Protection function to prevent signal propagation across AUX1 and AUX2A/B when either VREF1 or VREF2 voltage is invalid
  • Protection function to prevent signal propagation from HPD2 to HPD1 when VREF1 is invalid
  • Protection on AUX1 from over-voltage condition of AUX2A and AUX2B
  • Leakage current between VREF1 and VREF2 limited to 100nA 0MHz, -3dB Bandwidth for AUX switches
  • Complies with DisplayPort 2.0
  • Complies with HDMI 2.1
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
  • Halogen and Antimony Free. “Green” Device (Note 3)
  • For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/
