Default Dir1703?

Does BB still make a digital audio interface receiver?
Can't find it anywhere on the TI site.

Last thing I know that is that it was taken out of production because of some unlock bug. It's still a good receiver though, very low jitter specs. Me and my audio buddy experimented with it and it sounded ver nice.
Digi-Key still have them in stock.

Regards

If you want I can mail you the data sheet (300kb)

Thank you, I do have the datasheet.
I hope BB will produce a new version, the jitter as you say is very low.

I use this chip in my DIY dac with a pcm1730.

it works fine, any problem of locking in any sample frequency.

I use a 24,57 mhz cristal.

I use it with my cd player 44.1khz and with my dvd 48 khz and 96 khz.

I don't have to do any reset when changing of sampling frequency.

Excuse me for my poor english
