ADV7170/ADV7171
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADV7170/ADV7171 feature proprietary ESD protection circuitry, permanent
damage may occur on devices subjected to high energy electrostatic discharges. Therefore, pr oper
ESD precautions are recommended to avoid performance degradation or loss of functionality.

PACKAGE THERMAL PERFORMANCE
The 44-PQFP package used for this device takes advantage of
an ADI patented thermal coastline lead frame construction. This
maximizes heat transfer into the leads and reduces the package
thermal resistance.
The junction-to-ambient (
four-layer PCB is 35.5 C/W. The junction-to-case thermal resis-
