Hi to all ah sir and ching,


I don't know much about electronic circuits but I like to upgrade my Cambridge 840c master clock to a OCXO clock with this http://item.taobao.com/item.htm?id=330093850
I know there is 1 clock X1 24.576Mhz on Dac DSP Circuit board with 4 pins, 2 clocks on servo circuit board X1 16.9344Mhz and X2 7.3728Mhz with 2 pins each.  Just want to see any ah sir can help me out, if I want to run 解碼和轉盆用上同步的Clock signal please help me with the following:
1) Should I get OCXO with 24.576Mhz?
2) Would OCXO 27.000Mhz work?
3) How to hook up, I think the OCXO has power input,  two output 1 being the clock signal and the other ground.  Which pin should it be connected to on DAC DSP X1?  How to connect to clocks on servo board.  Since the clocks on servo board only have 2 pins, does it matter which pin is connected to clock and ground?  Is the hook up below correct?

I think the circuits diagrams may not be too clear, I can send you the pdf file if required.  Please give me your email address.  Thank you very much in advance!
