Jitter measurement of a typical isochronus USB transport .

 

 

jitter1

This is the jitter present on the word clock of the transport before even the spdif transmission to the dac.

Jitter measurement,present on the wordclock of the converters of Kassandra dac, using the USB transport.

jitter2

Jitter distribution measurement, of word clock synchonising the 24 converters of the Kassandra DAC, with the internal reclocker enabled, using the same USB converter.

jitter3

Jitter distribution, after double reclocking of the wordsync clock.
