board at both 96k and 192k and the results are very good.</FONT></DIV>

<DIV><FONT face=Arial size=2>What is really pleasing is at 192k there is no sign
of the 48k clock feeding the TLV320 Codec which was a problem with my
breadboard. The total lack of spurs is a credit to Lyle's PCB layout
skills!</FONT></DIV>

<DIV><FONT face=Arial size=2>By using the automatic calibration function on the
AK5394A chip I've also been able to reduce the DC offset by a futher 10dB.

<DIV><FONT face=Arial size=2>All the other Janus board functions check out OK so
looks like we have a 100% functional Alpha PCB.</FONT></DIV>
