Re: Why McIntosh use CS8416?

nagaesan said:
McIntosh MCD500 has 192kHz24bit digital input RCA terminal.
I checked this Digital Interface Reciever IC, it was CS8416.
I wonder why McIntosh uses CS8416 conventional PLL DIR-IC, because ES9008S has very nice non PLL / Time stump based DIR circuit.

Do you know who it is?


My guess is they used it for convenience, since they needed to multiplex multiple SPDIF inputs.

The ES9008 has no provision to multiplex SPDIF.

Cheers!

TOS-Link reciever device of MCD500

Recieving OPT Device is this.
I do not know this is 4times speed(DVD-Audio 192kHz is OK)
or 2times speed(DVD-Video 96kHz)

But I already checked it, MCD500 can recieving 192kHz 24bit.
How I checked it, that I build up Audio PC, installed RME HDSP9632 sound-card.
RME HDSP9632 support 192kHz24bit
And I used "Adobe Audition" sound editting software.

OPA627 on ES9008S eva-board

Today I changed I/V OP-Amp on ES9008S eva-board AD797 to OPA627.

I think AD797 is a nice low noise good performance OP-Amp.
But I want more faster OP-Amp for I/V stage.
I changed I/V OP-Amp, AD797 to OPA627.
OPA627 is high slew rate and short settling time than AD797.
