IP4776CZ38

Fully integrated HDMI interface with level shifter, ESD and

backdrive protection

Rev. 6 — 7 January 2011

Product data sheet

1. General description

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.

2. 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

3. Applications

The IP4776CZ38 is designed for HDMI receiver and transmitter port protection, level

shifting and backdrive protection e.g.:

Graphics card

Set-top box

DVD

Digital media adapter

Game console
