Is Pioneer PE8001A legatolink dac just a PCM1716?

Hi!

I have been searching the net to find the datasheet of the PE8001A dac in my Pioneer cd-player without finding it. Then I found the datasheet of the BB PCM1716 and both the pin layout and the internal block diagram is identical.

Is the Pioneer dac just a PCM1716 with pioneer wrapping?

I hope not, haven`t heard much good things about the 1716!

Anybody know if this is the same chip?

Thanks

I think so but i have no proof. There are no differences that i can see at least.

Does Legato link not refer to the filter part of the conversion process rather than the actual DAC used? Same as what others call up-sampling. That's what I thought. The filter uses a Pioneer proprietary algorithm, aka Legato Link, for the up-sampling/interpolation and then feeds the ordinary DAC with that data. In the Hi-Bit version it simply means that the DAC chip is more than 16 bits...

Hi!
Thanks for answering!

UrSv and hjelm, you are probably right. The "High bit" chip in this player is a 16 pin dip chip infront of the dac. Pioneer was ahead of time and had this upsampling chip in way before everybody else started raving about it!

I guess that the datasheet for the 1716 is valid for the Pioneer dac aswell.

Thanks
