Default SAA7220 queries


From this reclocking thread..


I did some more digging on the saa7220, and found what I wanted from an Analogue Device application note AN-207 which is posted elsewhere on the forum in regards to the ad1865 dac,


Saa7220 questions:-

-Is that pre-emphasis of +1.0db at 20Khz correct ?

-Anyone know the stopband attenuation of the saa7220 ? (I want to compare with other filters)

In the end if I 'upgrade' the saa7220 I will probably need to upgrade the tda1541a aswell.

I have thought about this module but I haven't received a response to what DAC is on the board http://www.obantec.co.uk/html/products_4.html

I doubt they will tell me!

Kind regards,
