c'mon guys, lets put our heads together to control a STA310 ac3 decoder

[elnec]

Hi all,

can somebody sent me schematic and details for sta310?

Regrads,
Elnec

Hi,TriLithium,Can you email the newly STA310 datasheet to me?
many thanks!

Hi,TriLithium,Can you email the newly STA310 datasheet to me?
many thanks!

I believe still only the preliminary datasheet is available. I'll be testing my implementation of the STA310 (based on the preliminary data) in the upcoming weeks (currently testing the analog part of my preamp). So i'll post my results then.

Hi,H0rus
How can i configuration the internal audio PLL?
AU_PLL_FRACL_192 and the like.
Thanks!

 

[TriLithium]

Nothing has to be done to the PLL fraction registers. These will be set by the MCU when a stream is detected. I have never had to modify them.

 

[sz_ahong]

How can i change the system clock?
After hard reset the system clock is running at 47.25MHz

 

[sz_ahong]

Now my STA310 can working!

 

[TriLithium]

Good to hear, another DIY STA310 is able to work. Very nice.

 

[sz_ahong]

What about the STA310 sound quality?
I want use sta310 + PCM1792 + OPA2134 build a HI-FI AV receiver.
Dose anybody give me some suggest?
Thanks!
My english is poor!

 

[TriLithium]

That will be just fine. No normal AV receiver will sound like that, only the $1500+ brands will be in that game.

The setup on my pictures were with a PCM1798 and OPA134. Pretty similar. It sounded fine on the 2 channels that I made.
Just make sure you make the traces as short as possible on the analogue side with proper short grounds. Opamps work at their best with it.

 

[H0rus]

Nice one
sz_ahong,

I cant wait to test mine (I'm using sta310 + PCM1792 + LM4562) but got quite some analog mixing/tone to debug first.
(And just smoked part of my power supply..arg crappy temporary heatsink mount)

 

[sz_ahong]

Oh,It looks like well, I will try it!
Now my DAC is WOLFSON WM8746,It`s not so good.
Thanks!

HI all,

Can someone help me buy sta310 ?

 

[sz_ahong]

Hi,elnec, I can help you buy 1 or 2 chipset.
Email to me!

 

[elnec]

guys, it is possible that i can add hdd interface for this project?

 

[sz_ahong]

Yes,I think so!
you need write ATAPI protocol, then send data to STA310 via parallel or I2C port.

 

[elnec]

Hi ahong,
regarding ATA interface,, that i can do using atmega128 but the missing link is that i don't know how to use parallel interface of sta310

so help?

note : input port of sta310 use i2s inteface

 

[krzemyk]

Hope topic isn't dead.

Anyone get full working code for STA310?

I'm working on it hard, but for now it doesn't work

 

[H0rus]

I've been trying to get it to work too. I'v been able to get the beep and noise generators to work with my dacs (PCM1792). However havent been able to decode any music via the S/P-dif input.
Attached is my sta310 init routine, if you provide yours we can compare them.

 

[krzemyk]

I will publish mine next week if I don't make it works by myself.
