The IP4776CZ38 is designed for HDMI host-interface protection. The IP4776CZ38 includes level shifting for the DDC channels and backdrive protection for HDMI as well as high-level ESD protection diodes for the TMDS signal lines.

The level shifting function is required when the receiver operates at a supply voltage lower than the external devices to protect the I/Os against overvoltages. The IP4776CZ38 contains four N-channel MOSFETs to provide this level shifting function.

Furthermore, all TMDS intra-pairs are protected by a special diode configuration offering an ultra low line capacitance of 0.7 pF only. These diodes provide protection to downstream components from ESD voltages up to ±8 kV contact according to the IEC 61000-4-2, level 4 standard.

Features and benefits

  • Pb-free and RoHS compliant, Dark Green
  • Integrated high-level ESD protection, level shifting and backdrive protection
  • All TMDS lines with integrated rail-to-rail clamping diodes with downstream ESD protection of ±8 kV according to IEC 61000-4-2, level 4 standard
  • Matched 0.5 mm trace spacing
  • Bidirectional level shifting N-channel FETs provided for DDC clock and data channels
  • TMDS lines with ≤ 0.05 pF matching of capacitance between the TMDS pairs
  • Ultra low line capacitance of 0.7 pF per channel
  • HDMI 1.3 compliant
  • Backdrive protection
  • 38-pin TSSOP lead-free package

Applications

  • The IP4776CZ38 is designed for HDMI receiver and transmitter port protection, level shifting and backdrive protection e.g.:
    • TV
    • Graphics card
    • Set-top box
    • DVD
    • Digital media adapter
    • Game console
