THERMAL CHARACTERISTICS
The ADSP-21363 processor is rated for performance to a maxi-
mum junction temperature of 125°C.
Table 33
through
Table 36
airflow measurements comply with
JEDEC standards JESD51-2 and JESD51-6 and the junction-to-
board measurement complies with JESD51-8. Test board and
thermal via design comply with JEDEC standards JESD51-9
(Mini-BGA) and JESD51-5 (Integrated Heatsink LQFP). The
junction-to-case measurement complies with MIL- STD-883.
All measurements use a 2S2P JEDEC test board.
Industrial applications using the Mini-BGA package require
thermal vias, to an embedded ground plane, in the PCB. Refer to
JEDEC Standard JESD51-9 for printed circuit board thermal
ball land and thermal via design information. Industrial applica-
tions using the LQFP package require thermal trace squares and
thermal vias, to an embedded ground plane, in the PCB. The
bottom side heat slug must be soldered to the thermal trace
squares. Refer to JEDEC Standard JESD51-5 for more
information.
To determine the Junction Temperature of the device while on
the application PCB, use:
