Can be configured as follows:
Internal clock:
The clock for the transmitter is derived from the internal clock. The internal clock has an accuracy of
+/- 3.5ppm conforming to G.812 recommendations.
External clock:
The clock for the transmitter is derived from
2Mbps (or 1.5Mbps) signal
2MHz (or 1.5MHz) BITS clock
64Kbps (co-directional) present on the SMA connector

box.
Rx:
The clock for the transmitter is derived from the received signal and the jitter of the incoming signal is
suppressed.
