問CD workshop送套件.

1)電源瀘波
欠電阻.要買幾多數席.幾大V數,焊接時那一個零件要分十∕一.怎樣分.

2)綠燈
可在那裡另購買多D.

3)74HC Chip
應加在CD那裡.加後有什麼妀進

Hello

Ans your question below:

Q1
Admin will send the conneciton diagram to you by Email.

Q2.
You can ask Admin to arrange.

Q3.
Any CDP/DVD have build on board, adding a buffer will make the switching time faster and sharper

KK, 請問是否只需要將Chips放在原有的上面做並聯便可 ???

Louis,

Don't. Please make sure your circuit connection first.
If possible, please post your CDP photo at here.

KK.

DUALXEON

Resistor 1*10Mohm, 2W (You may buy a few more for safe)

For +/- you need to make sure the choke connect with the same orientation as in the circuit diagram

Thanks

can I to know is it  filter will work 100V to 220V
 樓主| DUALXEON 發表於 2006-4-13 00:30:55 | 顯示全部樓層

May I to know anyone finish this work.

Dualxeon,

Please tell me about your value of the resistor.
Should be 10M 1W.

NOT 10 ohm!!!!!

KK.

Louis,

Your 74HC04 is not using in the Digital out.

This 74HC04 is use as oscillator work together with the Crystal

如果並聯在這麼沒有幫助的話, 這裡換CLOCK又有沒有幫助呢?
kk_ho 發表於 2006-4-19 00:18:25 | 顯示全部樓層
Louisla,

First, I assume that logic gate is for clock oscillator.

From the point of view of electronic circuit theory, the crystal itself cannot oscillate, it need something to make it oscillate, that IC form a simple loop back oscillation for the crystal.

If you parallel it, it can improve the jitter a little bit.

Hope this help.

KK.Ho
