Introducing OTTO2
 
1 Attachment(s)
I think a picture is worth a thousand words.

I will just say it works beautifully - and I have tested it with signals up to 100Mhz master clocks. :)

We have a small qty available very soon, and more to come thereafter.

This cct can be used to switch between DSD sources and PCM or between two PCM sources etc.

The concept is simple. You have a common four channels(A) and two sets of 4 switched channels(B1 and B2). The set that is selected is dependent on the state of the "S" input. The OE(bar) input must be low (jumper to GND) for the output to be enabled.

Pretty easy.

The MUX works with a VCC input of 3.3V to 7V(max) I recommend 5-5.5V the signals that are used should be equal to or less than VCC.

Cheers!

Some features:

-Less Than 0.25 ns−Max Delay Through Switch
-No Circuit Bounce

If I get this right I can use this fi. to switch between two I2S sources?

Russ White 26th July 2012 10:45 AM

Yes. :) OR two DSD sources - or a DSD and a PCM source.

Your welcome. :) I try.

Nice...
 
This is exactly what a lot of people will be looking for, especially as DSD capable computer interfaces become more available.
Looks like it also is set up for U.FL, right?

Russ White 26th July 2012 01:37 PM

No current version (first batch) has no UFL support. We will probably add UFL pads on the next run of PCBs after these are gone. These will be pretty inexpensive.

Exactly, people like me :)

@Russ: Do you know already how much it going to cost?

Russ White 26th July 2012 02:19 PM

Brian and I talked yesterday about it and we are looking at $29.
