The schematics for the eZdsp
that accompanies this board. The schematics were drawn on ORCAD.
The schematics are correct for both the socketed and unsocketed version
of the eZdsp
Design Notes:
1. The TMS320F28335 X1/CLKIN pin is +1.8 volt input. The clock input is
buffered with a SN74LVC1G14 whose supply is +1.8 volts. This provides
+3.3 volts to the +1.8 volt clock translation. Refer to sheet 4 of the
schematics.
The TMS320F28335 supports +3.3V Input/Output levels
which are NOT +5V tolerant. Connecting the eZdsp to
a system with +5V Input/Output levels will damage the
TMS320F28335. If the eZdsp is connected to another
target then the eZdsp must be powered up first and
powered down last to prevent lactchup conditions.
