Hi Sharedoc
I have a question.
I saw your topics about Turbo PLL.
Could you explain IC name of PLL Circuit and Peak to Peak Voltage of 14.318MHz Wave?
And 600E and 600X has a same PLL Circuit?
I have a 600X Main Board for traning.
Always Thank you for your topics

IMI SG577. Original data sheet is no more available in the web, but equivalent spec can be downloaded
http://www.standardics.philips.com/prod ... ck2000.pdf
peak-to-peak 3,3V to my understanding (defined by Vref = pin#48)
I always drive reference clock outputs with at least 100ohm resistor for protection.

No, 600X uses different clock generator. I don't remember the code, but it is an IMI type as well. I have to check.
> I have a 600X Main Board for traning.
I have also one extra 600X board.

Good info on TurboPLL

I suspect the clock generator to be IMI C9714AYB.
Unfortunately I don't have data sheet
Maybe it is equivalent to this Philips type?
