about SAA7310P

[haitaku13gou]

Hello,
I'm looking for SAA7310P.
Last "P" means DIL package.
So, please tell me CD players useing SAA7310P.

I have junk CD99, and I want fix this old good CDP.....

 

[haitaku13gou]

I find marantz CD50 at yahoo auction in japan.
This may be has SAA7310P,
and there are many photos of inside of CD50,
but I can't detect surely it has SAA7310P.
"motherboard" of CD50 is a same one of marantz CD40, CD60.
Anybody own CD40,50,60, please give me information.

 

[weissi]

hi!

yes, the cd50 uses a saa7310 -- but not in a dil package
I think they are very rare... sorry....

 

[haitaku13gou]

Thanks weissi.
SAA7310P are rare?
Looks like they are hard to find.
Well, I'll find SAA7210.
Do you know which CDP has this device?

Marantz CD42, CD52, CD 72 for sure. In DIP.

Marantz CD42, CD52, CD 72 for sure. In DIP.

Strange, my Marantz CD62 has an SMD version

 

[haitaku13gou]

Thanks, arniel, Bricolo.
ok, I'll find CD42,52,62.
But I think if I get CD50, I can make a QFP-DIL converter board.
It seems not hard work.

SMD version?
Data sheet not say anything about such package!

 

[haitaku13gou]

Marantz CD42, CD52, CD 72 for sure. In DIP.

Is this comment about 7310 or 7210?

 

[haitaku13gou]

Sorry, I did crazy response.
SMD version = QFP.
And I found picture of CD72.
CD72 has SMD(=QFP) version!!

arniel, are you sure?
CD42,52,62,72 all seems QFP version saa7310.

I think you're right... I was getting confused with the digital filter!
The CD42 is very similar to the CD72 in most parts...

 

[haitaku13gou]

Thanks�@arniel.
I'm getting have an idea transplanting SMD-version saa7310 to my marantz CD99. But I'm afraid of other device is broken.
Other device means IR2339(compareter), MN4264P-15(RAM).
I broke these devices by adding 20V!!
So, it's more safer solution getting CD880(having very similer�@devices to CD99) than getting CD50(has SAA7310 SMD version).
I don't know what happen when install SAA7310, and CD50 may be not have other necesary devices.

 

[arniel]

Please don't take this the wrong way, but is it really worth the effort? Depending on where you inserted the current, chances are every IC on the mainboard is broken!

 

[haitaku13gou]

Exactly!
But there is a little hope.
I added 20V to saa7310, compareter and DRAM, but not to other devices. CD99 has several boards, and I tried separate power supply between servo system and signal processing one.
I added high voltage to only one board.
But, of course, other boards connected by signal line, it is possible many other ICs damaged!!!!

 

[haitaku13gou]

After that.....

Hello, everyone.
After that, I get marantz cd650, and it has SAA7310PB and DRAM.
So I transplanted SAA7310PB and DRAM to my cd99.
And I can repair my CD99.
By the way, comparetor is not damaged.
Thanks all.

Mmm, a marantz 650, never heard of. Is it the philips 650 sold as marantz in japan??? If so, you should have found a 7210 in there (or a M4xxx chip). I think there are some small differences between 7210 and 7310, check the datasheets.

regards,

 

[haitaku13gou]

Thanks for reply, guido.
I don't know phillips CD650.

But may be you right.
There are many marantz CDPs in Japan,
but they have phillips devices.

my marantz cd650 has devices like this,

CDM2
SAA7210P/A
SAA7220P/A
TDA1541

SAA7310 is a SMD version of SAA7210, isn't it?
I did mistake.
My CD650 has not SAA7310P/B, but SAA7210P/A.
My CD99 originaly had SAA7210P,
and I change this device to SAA7210P/B.
My original CD99 sometime has trouble when TOC reading,
but after change decorder/controler to SAA7210P/A,
my CD99 reads correctly TOC.

Yep, that's a philips CD650, also sold as magnavox (got that one myself). 7310 is NOT 7210 in smd, it is a more advanced version of 7210. Differences can be found in the datasheets.

Dunno much of the differences between the P, P/A and P/B versions of 7210. Maybe that P/B is just broken...
Did you try it in the 650?

Congrats you got it working.

 

[haitaku13gou]

Sorry, I did mistake moreover.
My CD99 has SAA7210P, and I change it to SAA7210P/"A" from
CD650.
So, I tryed it in CD99.
CD650 is just a donner.
CDM2 is in my junk box.

Sounds something different when TOC reading
between SAA7210P and SAA7210P/A.
SAA7210P/A sounds like read TOC again and again until success.
But SAA7210P gives up immediately.
