1)我個CD CLock 是幾多PPm.
2)個CD CLock 是幾多DC Watt 工作電壓.因想加一隻獨立牛及穩厭給CD CLock.

1.以我所知是2ppm.
2.工作電壓是5V，如要加一隻獨立牛要用9V左右，另加一穩壓電源。

Modi 兄


多謝你提拱以上知訉.

我希望KK Sir 可以confirm.因我是叫人幫我做,自己唔夠班做.

順便一提,CD PLAYER 經摩改後.細陳生聽過說低音量多及我朋友Jeo拿回家聽也說量多.但是我自己覺得0K.有機會可否要Modi兄幫吓耳.指點下.

Dualxeon,

Sorry for latest reply, customer visit and meeting everyday.....need to get more $ for Q4 order.

For my clock, the Accuracy is 2ppm. Jitter is < 3 ps.
Accuracy is not more important in the clock, the most important thing is jitter as I explain in the CD course class I and II.

For the voltage, the TCXO device (siliver colour) is 5V, but I adding a post regualtor (super regulator) for TCXO, the supply voltage is 12V.

You can adding additional transformer + rectifier to this. No need extra LM317. Simple 8.5V AC transformer + full bridge rectifier + capacitor to my board is OK.


Hope this help.
