如何用SAA7220给SAA7310GP加数字输出????
请上个图!!谢谢!!!改天发个图给你
我制作过,改天发个图给你,现在上班没带过来.我也要图纸,麻烦老卢给一份,谢谢.
bbf_814@tom.com你的CD机显示板图纸有吗?
以下是引用阿卢在2005-7-5 15:03:00的发言:我用7310加7220就有同轴输出了,不用动原线路,在7310的1至4脚引出线接上7220的相应脚就行了,并将7310的26脚接7220的晶振输入脚就行了<img src="attachments/dvbbs/2005-7/20057515313747.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/2005-7/20057515313747.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
能给个我吗?

谢谢。
我明天将图纸传组你

很好,谢谢碰碰车!
唉
资料很不清楚,有点遗憾。不好意思,现在我才看到
不好意思,现在我才看到,我也没有弄过。你还是问鬼版好一点。pdf地址在这里http://www.alldatasheet.com/datasheet-pdf/view/PHILIPS/SAA7220.html看能不能帮到你了。呵呵
回楼上
谢谢,不过打不开!这里有SAA7220的资料下载,复制连接再粘贴到浏览器才能打开
http://www.tiking.com/compment.asp?compment=PHILIPS\SAA7220.pdf55555555SAA以前看过一下
先粗调聚焦线圈在零位(目测),然后调节时测另外一个地方的电压,调 至规定值。。。具体忘了。如果你找到老的菲利浦CD机的维修手册应该有讲。另外一个,我曾试过,但也忘了。请教小鬼头
聚集线圈怎样调?是不是应有个测试点?调节光功率应有作用,正常RF网波是1.2V左右!因手头没有资料,不敢乱调,光功率电阻顺时针方向调是不是光功率变大?回楼上的,这个配置一般有两个微调
一个调聚焦线圈的偏置(零位),一个调光头功率。。。。但IC内有已有光头功率自动控制的功能,可能调节范围比较小。。。。不知道调节他的效果是不是象CDM12。1那些光头那样不直观。我知道的就这些
碰碰车,你好!
你可不可以给我一个TDA5708,SAA7210,SAA7220的整个电路图,我想把CD机重新调一下,但找不到RF信号调整点!正在研究中,相信很快会有结果!!
可以参考7220的pdf啊
可以参考7220的pdf啊。文件太大我传不上来啊,我截图给你看吧<img src="attachments/dvbbs/2005-7/200572153726749.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/2005-7/200572153726749.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
查了一下手头的资料
证实SAA7310可以和SAA7220相接。但没有直接的相接图。我觉得里面的关键是之间接好四条线,一是系统时钟线(需将SAA7310的晶体振荡电路取消,改为使用SAA7220的,并将信号送到7310),二至四是I2S的三条线,五是EF误差信号。后面的4条线均是从7310送至7220。
