自本刊今年第一期起刊登了笔者改装VCD积累的一点心得以后,不断收到来自全国各地的电话和信件,现针对大家提出的共性问题再作一点补充。1.关于DA—XCLK 从CD-DSP引出的时钟信号必须注意其晶振频率的大小,当其值为11.28MHz或16.93MHz才可引用,并且要用单线或同轴电缆传送,否则有时会出现其它问题。一般DSP连 Since the publication of the first issue of this year, I have accumulated a little bit of experience in converting VCDs and have continuously received calls and letters from all over the country. 1. About DA-XCLK The clock signal from CD-DSP must pay attention to its crystal frequency, its value is 11.28MHz or 16.93MHz can be quoted, and it should be transmitted by single wire or coaxial cable, or sometimes there will be other problem.
