My new stuff -- Super low jitter DAIR modular pin compatible with 8412/8414

wenye · 13th April 2006, 10:10 AM

It's a super low jitter modular design. I spend around half a year to design and I just finish the first sample.

I named it "Verse-dair".

Performance testing just finished in these few days, the result is very interesting.

I compare the spec with CD8414 as following

1. Jitter:

"Verse-dair"
from 10Hz-1MHz from carrier will be lower than 20ps RMS.

"CS8414"
from ???KHz--???MHz from carrier (no spec) , typical 200ps RMS.

2. Jitter attenuation range

"Verse-dair"
From 10Hz-1MHz from carrier >40dB

"CS8414"
From 20KHz -3dB ~ 1MHz -35dB linear attenuation curve (-6dB / double the frequency)

3. Receiving sampling range: same to CS8414

4. Functionally: pin function compatible with CS8414, pin out compatible with CS8412 in DIP-28 package

The modular on the photo is Mr. "Verse-dair"

Very interesting. What sample rates does it support?

wenye · 13th April 2006, 03:17 PM

The sampling range that "Verse-dair" can support from 8Khz to 96khz

Look like you did a nice job....

As this is a DIY Forum I have immediately 2 questions

1. How does it sound compared with a CS8412/14
2. Can you publish the circuit, so we now what you have been doing ?

thanks

Do you really expect an answer to that question Doede ?

Did you look at the pics carefully ?

chris719 · 13th April 2006, 06:05 PM

Looks like some kind of PLD or FPGA and most likely a commercial 'kit' type product.

That's a good point. Note the sticker over the chip

Wenye, if you need a volounteer for testing/evaluating the module you can send me one

I am curious how it compares to CS8412.

jleaman · 13th April 2006, 06:42 PM

Id like to point out , THAT board looks really good well done.
