power supply need three AC power input, two of which provide power to the CDPRO module,while the remaining one to provide power to the display board,CDPRO module power seq... is:
--------cdpro 5v---------cdpro 9v----
--------<4.5--------------1.25v-------
-------->=4.5v-----------9.00v-------
the boot sequence is requirements of CDPRO manuals;


Display is VFD dot matrix(80*16),use AT8051 driver cdpro module(via dsa protocol),ATmega8 driver vfd;function has been achieved follows:
seq play,shuffle play,play A time till B time;
pause play;
forward,backward;
repeat one/all;
close/open vfd;
support Philips standard remote control.


Digital output board using TI DIT4192(I2S to SPDIF conversion).
