Hi!

I've just received a packet with twisted things in it :)
Since I am very exited about it, I am going to build it ASAP... as perfectionist I have some comments/questions:
- Buffalo WWW page states: "The Buffalo module requires two supply voltages. VA should be run at 6.6VDC and VD should be run at 5VDC. We offer a combination of the Buffalo and our Low Current Dual Power Supply (LCDPS) below.", manual recommends 6.6VDC and 6V. I guess 6V is "more recommended" :)
- I look at the Buffalo board schematics and I cannot figure it out where VA goes, I guess to DAC (is there a DAC chip datasheet available?)... but in schematics it points to nowhere :S
- I've noticed there are 2 REGs on the board, 2 are used for digital, right? How good PSU has to be (I have LCDPS)?
- Should I try to make analog PS as quiet as possible; since VA is (?) routed directly to DAC chip?

Thanks,
Matej

hello,

On the Buffalo there are four power supply terminal. VA, and GND, and VD and GND. I hope this answers your questions. :)

I would not change the VREGs unless you feel a special need. They work great,

Hi can someone tells me what masterclock, i can use when i read the datasheet, it tells me, if i use spdif input the clock must be 386x192= 74,112 mhz is this correct?
