1. General description
2. Features
The IP4777CZ38 is designed for HDMI transmitter host interface protection. The
IP4777CZ38 includes DDC buffering and decoupling, hot plug detect, backdrive
protection, CEC slew rate control, and high-level ESD protection diodes for the TMDS
lines.
The DDC lines use a new buffering concept which decouples the internal capacitive load
from the external capacitive load. This allows greater design flexibility of the DDC lines
with respect to the maximum load of 50 pF specified in the HDMI 1.3 specification . This
buffering also boosts the DDC signals, allowing the use of longer HDMI cables having a
higher capacitive load than 700 pF. The CEC slew rate limiter prevents ringing on the CEC
line. The internal hot plug detect module simplifies the application of the HDMI transmitter
to control the hot plug signal.
The DDC, hot plug and CEC lines are backdrive protected to guarantee HDMI interface
signals are not pulled down if the system is powered down or enters standby mode.
All TMDS intra-pairs are protected by a special diode configuration offering a low line
capacitance of 0.7 pF only (to ground) and 0.05 pF between the TMDS pairs. These
diodes provide protection to components downstream from ESD voltages of up to 8 kV
contact in accordance with the IEC 61000-4-2, level 4 standard.
