Hello All,
I'm trying to find out if the DSP56374 is "5 Volt" tolerant on the input
EXtal pin. The DSP56371 is according to the UG - but I'm not sure if the
DSP56374 is as I'd like to use an external XO. All other inputs are 5V
tolerant - but I can't find anything on the clock. Does anybody know?
brgrds,
Paul

Hello Paul,
According to DSP56374's datasheet, EXTAL is not 5V tolerant (see page 6,
table 3, note 1 and page 7, table 7), however it would be simple to adapt
voltage levels with a two resistor voltage divider.
Regards,
Pablo
