这个是我参考ti的EZf2812设计的,附上电路图。
Design Notes:
1. The TMS320F2812 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.http://bbs.chinaecnet.com/uploadImages/ezf2812_techref.rar
