好老明兄!我补上一张陶瓷04的图吧!
是54LS04DMQB,军用陶瓷的
<img src="attachments/dvbbs/2005-4/2005430141831854.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-4/2005430141831854.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
顺便给你看看我早年做的CS8412+TDA1311的解码
<img src="attachments/dvbbs/2005-4/2005430141929285.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-4/2005430141929285.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
里面用的TDA1311A
<img src="attachments/dvbbs/2005-4/200543014200644.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-4/200543014200644.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
给你看看背面吧!我是用电池供电的,也可以用单端5V,我为了试验,并了好多电容上去,效果不错,虽然太乱不好看!而且你看我的布线,所有的地线和+V,都不是同一根线的!要分开来,就是绞成成的那一股线!然后板上的各部分滤波也严格分开!这一点很重要!要不信噪比等一些指标不会高的!呵呵
