THERMAL CHARACTERISTICS
The ADSP-21367/ADSP-21368/ADSP-21369 processors are
rated for performance over the temperature range specified in
Operating Conditions on Page
Table 43
JEDEC standards JESD51-2 and JESD51-6 and the junction-to-
board measurement complies with JESD51-8. Test board design
complies with JEDEC standards JESD51-9 (BGA_ED) and
JESD51-8 (LQFP_EP). The junction-to-case measurement com-
plies with MIL-STD-883. All measurements use a 2S2P JEDEC
test board.
The LQFP-EP package requires thermal trace squares and ther-
mal vias, to an embedded ground plane, in the PCB. Refer to
JEDEC standard JESD51-5 for more information.
