Hi roender,

The BIII DAC does accept "No Bandwidth". It's the DPLL BW Default switch setting.

Best regards,

Al

it is whird. Why does tackbon not generate BCLK via dividing MCLK?
Can it call "sync MCLK"?

In that case, I have to proudly declare that my setup is unlock free. Not a single unlock from power on till the end after almost one hour of listening.

My assumption is that it was much simpler to access the shifter supply on the chip by external connection rather than internal.
That is my understanding from ESS.

roender, nice job. Really like your setup. Just curious, can you try an spdif input with the DPLL set to "No Bandwidth" and DPLL Multiplier set to 1X to see if your setup still maintains lock? Thanks!

I just powered on the DVD player and voila, no unlocks!
The DAC switches automatically from I2S to SPDIF when it sees signal on D3 which is connected via TOSLINK

Hi Brian,

Just to clarify. In Buffalo III, when setting the DPLL BW to Default is the "No Bandwidth" selection in Register 11 being used, and Register 25 set to "Allow all settings", or is Register 25 set to "Use the best DPLL bandwidth settings". Thanks!

Al

roender, I think I misspoke. After looking at the ES9018 DS, and the Buffalo III manual in more detail, I don't think Buffalo III allows for the "No Bandwidth" setting. I think the "Default" dip switch selection sets Register 25 in the ES9018 to "Use the best DPLL bandwidth settings" which is the initial default setting.

You are right, BIII doesn't support DPLL "No Bandwidth" setting.
What confuse me is why DPLL is up and running in sync mode?
