and DDCB_SDA.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated 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 power consumption when using the ADV7842, the
user is advised to turn off unused sections of the part.
Due to PCB metal variation, and therefore variation in PCB
heat conductivity, the value of θJA may differ for various PCBs.
The most efficient measurement solution is obtained using the
package surface temperature to estimate the die temperature
because this eliminates the variance associated with the JA θvalue.
The maximum junction temperature (TJ MAX) of 125°C must not be
exceeded. The following equation calculates the junction tempera-
ture using the measured package surface temperature and applies
only when no heat sink is used on the device under test (DUT):
( ) TJ = TS + Ψ JT ×WTOTAL
where:
TS is the package surface temperature (°C).
ΨJT = 0.5°C/W for the 256-ball BGA.
WTOTAL = (PVDD × IPVDD) + (0.4 × TVDD × ITVDD) +
(CVDD × ICVDD) + (AVDD × IAVDD) + (VDD × IVDD) +
(A × DVDDIO × IDVDDIO) + (VDD_SDRAM × I ) VDD_SDRAM
where:
0.4 reflects the 40% of TVDD power that is dissipated on the
part itself.
A = 0.5 when the output pixel clock is >74 MHz.
A = 0.75 when the output pixel clock is ≤74 MHz.
