[hpsdr] More Janus results<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV><FONT face=Arial size=2>I've now completed testing the prototype Janus
board at both 96k and 192k and the results are very good.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This image is at 96kHz (Janus
96.jpg)</FONT></DIV>

<DIV><FONT face=Arial size=2>and this at 192kHz (Janus 192k.jpg)</FONT></DIV>

<DIV><FONT face=Arial size=2></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></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.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<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>
