Stresses abovethoselisted under AbsoluteMaximumRatings

may cause permanent damageto the device. This is a stress

rating only; functional operation of the device at these orany

other conditions above thoseindicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

PACKAGE THERMAL PERFORMANCE

To reduce powerconsumption when using the ADV7614, the

user is advised to turn off unused sections of the part.

Due to printed circuit board (PCB)metal variation and, thus,

variation in PCB heat conductivity, the value of θJA may differ

for various PCBs.

The most efficient measurement solution is obtainedusing the

package surface temperatureto estimatethe die temperature

becausethis eliminatesthevarianceassociated with theθJA value.

The maximum junction temperature (TJ MAX)of 125°C must not

be exceeded. The following equation calculatesthe junction

temperature using the measuredpackage surface temperature

and applies only when no heat sinkis used on the device under

test (DUT):

TJ = TS + (ΨJT × WTOTAL)

where:

TS is the package surface temperature(°C).

ΨJT = 0.3°C/W for a 260-ball CSP_BGA.

WTOTAL = ((PVDD × IPVDD)+ (0.05 ×TVDD × ITVDD)+ (CVDD ×

ICVDD) + (DVDD × IDVDD) + (DVDDIO × IDVDDIO)).

Note that for WTOTAL, 5% of TVDD power is dissipated on the

part itself.
