Ok, I found something in Europe.
RS Components in Spain seems to be a good solution for me.
The price of the caps is much more expensive than on the US, but it's the cheapest I've found in Europe. Customs don't ask me for money, as this is the EU.
Btw, the VAT in Spain is only 16%.
Done.

Carlos or anyone:

I've finally got all the parts to build a Veroboard version of Carlos's reclocker. One potential SNAFU is that I accidentally ordered the SMD (TO-243) version of the 78L09 reg, not TO-92 (or larger). In the datasheet, Panasonic does not seem to diff. between the two WRT performance/elec. specs -- both can supposedly deliver 100mA. My question: can this small SMD reg. adequately power the mostly-through-hole-component-based reclocker circuit?

If you are going to use 3 or 4 74HC74 chips I would recommend a TO220 reg.
Otherwise you should be ok with TO-92 or SMD.

And if you give your VAT number, you can even be surprised with 0% VAT (as you are an individual)
It happened to me in some orders from Spain, Deutchland and Netherlands

Thx for your reply ...

Yeah, I was thinking the same thing. I'm, initially, going to use only one 74HC74 as I want to reclock just the awful SPDIF line. The reason for that is that my current outboard DAC has a better I/V than that in my Philips CDB-650 CDP, which is mostly stock. But once the THS4032s arrive, I'll move to the Philips 650 for all-in-one CD playback. And I can't wait for that !

Hehe... I hadn't read this entire thread... made my morning

Carlos: re your PCB reclocking module in this thread ... I assume the BCK buffer (the first 74HC74 on the board with the BCK label) is there just for generic convenience or NOS. I'm pretty sure that with your Philips CD-160 you're not using the garbage spewed out by the SAA7220 and, instead, using a clean clock divided by two -- correct?

As far as divide-by-two circuits, someone (perhaps you) recommended the low-skew Tom Napier design. Anything better than this?

Thx,
-h_m

Yes, I'm using divide by 2 directly from the clock.
In this board the first 74HC74 is used for BCK reclocking but you can easily cange it for divide by 2 by shunting pins 2 to 5.



Better, why? Doesn't it work well?

Because the Napier design has been out for a while, I'm always on the lookout for "new and improved"! Yup -- I do know about Tent's divide-by-2 that you attached. In fact, I'm using Tent's PS/decoupling suggestions -- ferrite bead, 10uF cap --for the Napier design.

Note the error in Guido's schematic: pins 2 and 6 should be connected togheter (not 2 and 5) !

Ops... yes, that's right.

Hi Carlos --

Just a quick note to say thanks for the board design. I built a version of it, using 3 PLLs and a couple component changes, to use with Guido's XO-DAC in my PCM2707->TDA1541A DAC.

Credit where credit is due, and I appreciate you making your IP available here for others to borrow at will.

Best Regards,
John

Thanks for your kind words, John.
Several members here have made suggestions to the final layout, so this is open for all to use at will, there's no IP here and nothing new, it's a simple reclock module, which may be handy in many situations.
Use and enjoy.

This unit has worked v. well for me! So has Elso's KC, which couples nicely with Carlos' reclocker.

I personally don't see any reason to buy one of the for-sale modules. Maybe they are a tad better (??) but you don't learn anything with them. The DIY designs evolve and improve over time, too.

I have done this CI to install it under a CD/DVD ROM drive .

To day the 75176 is replaced by a LTC 485 ( better signals) ,the " SPDIF output is a differential TX+,TX- link charged by a 150R .

I check it with a PLEXTOR 130A DVD drive .
The Oscillator is a TENT 33,... Mhz ,the regulators are Audiocom vers 1 regulators ,capas are
OSCON
I have good results
