Micro Clock MKIII XB line art

The Micro Clock MKIII XB is the most accurate word clock we’ve developed to date. With only 0.6pS RMS of jitter at the BNC outputs, it has less than one third of the jitter of the standard Micro Clock MKIII! It boasts incredibly accurate crystal oscillators and superior quality galvanic isolation, both of which contribute to the extraordinarily low jitter measurement.
