IP4778CZ38

The IP4778CZ38 is designed as one kind of HDMI ESD protection, DDC buffering and hot plug control device that includes DDC buffering, slew rate acceleration and decoupling, Hot Plug control, backdrive protection, CEC slew rate control, optional multiplexing of DDC signals, and high-level ESD protection diodes for all HDMI signals. And this device can be used in wide range of applications such as (1)TV; (2)Projectors; (3)PC monitors; (4)HDMI buffer modules (extensions of HDMI cable length); (5)HDMI picture performance quality enhancer modules.

Features of the IP4778CZ38 are:(1)HDMI 1.3 compliant; (2)Pb-free and RoHS compliant; (3)Robust ESD protection without degradation after several ESD strikes; (4)Low leakage even after several hundred ESD discharges; (5)Very high diode switching speed (ns) and low line capacitance of 0.7 pF to ground and 0.05 pF between channels ensures signal integrity; (6)DDC capacitive decoupling between system side and HDMI connector side and drive cable buffering with capacitive load (> 700 pF); (7)Hot Plug control for direct connection to system GPIO; (8)CEC ringing prevention by slew rate limiter; (9)DDC and Hot Plug enable signal for multiplexing and backdrive protection; (10)All TMDS lines with integrated rail-to-rail clamping diodes with downstream ESD protection of ±8 kV in accordance with IEC 61000-4-2, level 4; (11)Matched 0.5 mm trace spacing.

The absolute maximum ratings of the IP4778CZ38 can be summarized as:(1)supply voltage: GND-0.5 to 5.5 V;(2)input voltage: GND-0.5 to 5.5 V;(3)electrostatic discharge voltage: -8 to +8 kV or -2 to +2 kV;(4)total power dissipation: 8 mW;(5)storage temperature: -55 to +125 °C.
